Parking & Trailhead Information for Devil's Thumb Lake Hike
The parking at Hessie Trailhead is limited, so be sure to take some time to review these details before departing for your hike. Boulder County offers a shuttle that runs from Nederland every 15-20 minutes on weekends during the Summer months and on some holidays. For full details on the Hessie Trailhead Shuttle, please see the Boulder County page for the shuttle service. This shuttle departs from the RTD Park-n-Ride in Nederland.
Directions to Hessie Trailhead
At the roundabout in Nederland, Colorado, drive south onto CO-119/South Bridge St. Take a right onto Eldora Road which will take you to Elodora Colorado. The road continues through Eldora, and changes to Eldorado Road. It proceeds out of town and changes its name to Hessie Road. About 3/4 of a mile outside of Eldora, the road will split, 4th of July Road goes to the right, and Hessie will turn to the left. The 2WD Hessie Trailhead Parking area is at this split. Do not park alongside the road, as you will likely be fined. If the parking area is full, then go back to Nederland for the shuttle (weekends and holidays). There is parking for 4WD vehicles further up the dirt road and closer to the beginning of the official trail. It's important to know that rains can quickly flood this segment of Hessie Road.
The Hike: Devils Thumb Lake Trail
Most hikers will begin the hike up to Devils Thumb lake at the Hessie 2WD parking area. From here, pick up the trail that runs along the north side of the 4WD dirt road. The trail will run alongside a small pond, keeping to the right-side of the 4WD segment of Hessie Trailhead road until it arrives at the official trailhead. Moose frequent the wetlands on this segment of the trail, so be alert--you may get a chance to snap some photos of them. At approximately 1/2 mile from the shuttle drop, a sign marks the site of the old mining town of Hessie, Colorado. A bit further up, the trail will cross a footbridge over Middle Boulder Creek. Soon after the bridge, you'll find the official trailhead signage that provides a quick-reference map. Because this is a longer hike into demanding terrain, we recommend Trails Illustrated: Indian Peaks Wilderness map for this hike.
The Hike: Devil’s Thumb Lake Lake Trail
After crossing the bridge near the trailhead, the trail climbs the mountainside via an old mining road. After 1/4 mile, the forest gives way to a meadow and opens up to views breathtaking views of Rocky Mountain scenery. At the first intersection, both trails will lead to Devil's Thumb, and both options are approximately the same length. So, which one is best? The right-hand Devils Thumb Bypass trail was created for Spring and Early Summer hikers because the main Devil's Thumb segment can get thick with mud and drenched with water during the early snowmelt. Otherwise, the left-hand Devils Thumb Trail will be the most scenic.

Small waterfalls and cascades are spotted along the trail as it makes its way along Middle Boulder creek. Indian Peaks is also famous for its wildflowers in the early and mid-summer. If you've taken the Devils Thumb (main trail) then you'll encounter a second intersection with signage that points left to Lost Lake and King Lake, and right for Devils Thumb Lake, Jasper Lake, and Woodland Lake. Taking the right-hand trail will lead up to Devils with more small waterfalls, cascades, and wildflowers. The next intersection will have a left-hand trail that leads to Woodland Lake and a right-bearing trail that leads to Devils Thumb and Jasper Lakes. This is where the bypass trail joins up to the main trail from the southeast. And here is where the terrain becomes much more steep and challenging.
![]()
About 1/2 mile before the side-trail for Jasper Lake, a trail sign will point the way northeast to Diamond Lake. However, Diamond Lake is best accessed via the 4th of July Trailhead. Jasper Lake is every bit as beautiful as Devils Thumb Lake and is worth stopping to take in the views. However, be mindful of the weather, especially during the Summer months when afternoon thunderstorms can explode onto the scene without much warning.

It's just 1 mile from Jasper Lake up to Devils Thumb Lake. The lake is named after the tower of rock prominent upon the ridge above its waters. The Thumb can be seen from many miles away when driving Hwy 40 near Winter Park, Colorado.

Trail Map for Lost Lake Hike

The Hike: Lost Lake Trail
If taking the shuttle, it will drop you off at the 2WD parking area. From here, hikers will follow a trail for that runs along the north side of the 4WD dirt road. The trail runs past a small pond and will keep to the right-side of the 4WD Hessie Trailhead road until it arrives at the official trailhead. Keep your eyes peeled for Moose who frequent these waterlogged meadows along this lowland segment of the trail. At approximately 1/2 mile from the shuttle drop, a sign marks the site of the old mining town of Hessie, Colorado.

Soon, the trail will cross the North Fork of Middle Boulder Creek via a footbridge and a large sign will map and describe the several trails and destinations that can be accessed from this point. Hikers will continue on this old mining road as it leads uphill towards both Lost Lake and the intersection for the trails that lead to Devil's Thumb Lake, Jasper Lake, Woodland Lake, King Lake, and Bob and Betty Lakes. This trail profile will describe the route to Lost Lake only.
The next 1.2 miles climbs by way of switchbacks over rocky and steep terrain. Wildflowers pepper the trailsides and the riparian zone along Middle Boulder Creek. At the first trail intersection (Devils Thumb and Devils Thumb Bypass Trails), a sign will mark the way to Lost Lake and give distances and point the direction to the other destinations. Here the trail to Lost Lake will go left and cross another footbridge. Soon, a waterfall and set of cascades will come into view. The trail will make its way to a second intersection and sign. Here, the trail for Lost Lake departs, once again, to the left.

From this point, Lost Lake is just 1/2 mile away. It's a steep segment but worth the views when you arrive. At Lost Lake, hikers can explore the outside circuit of its shores (this will add both time and distance to the hike). Return via the same trails for a total of 4 miles.

Parking & Trailhead Information for Chief Mountain Hike
From Denver, take Interstate 70 west to exit 252. This exit will funnel you onto CO-74/Evergreen Parkway headed West/Southwest for about 2 miles, where you'll take a right onto Squaw Pass Road. Squaw Pass road is paved and climbs the mountain in a series of switchback for 10.4 miles. The trailhead is easy to miss. It's a pull-out on the right-hand/North side of the road. It's worth taking a look at the parking area using satellite view on Google maps before going. You'll notice that the trail begins just a bit East of the parking area on the South side of the road. We've dropped the pin in the driving directions above at the location of the trailhead. As with all roads at this altitude, be sure to check conditions and closures before setting out.

The Hike: Chief Mountain Trail
The Chief Mountain trail begins on the south side of Squaw Pass road. The trail starts out as a steep 1/4 mile segment that takes hikers through dense alpine forest to Old Squaw Pass Road. The trail is picked up again on the other side of the dirt road and marked by signage. The trail bends now along the base of Papoose Mountain and the dense forest gives way to scattered trees and eventually into high-country tundra. Colorado's tundra ecosystems are incredibly fragile. Here the alpine flowers and lichens grow close to the ground in order to survive in the harsh winds and cold. Stay on maintained trails as it can literally take centuries for this alpine environment to recover from the damage inflicted upon it by foot traffic.
The trail should be evident, but you'll also find that it is marked by blaze marks on some of the trees. The trail becomes more demanding and steep. With each switchback new panoramas reveal distant snow-capped landscapes. Jagged rock formations grow in size as the trail gains elevation and makes its way closer to the summit.
The views are incredible at the top (see photo below). Mount Evans can be seen to the West and Squaw Mountain to the East. This is a great vantage point for taking in the changing aspens along the Front Range of Colorado. For more Fall Hikes, see our 25+ Hikes for Viewing the Changing Aspens in Colorado.

Parking & Trailhead Information for Booth Creek Falls Hike
To get to the Booth Creek Falls Trailhead from Denver, follow interstate 70 West until you reach East Vail. Take exit 180. At the first intersection, make a right, then an almost immediate left onto the I-70 Frontage Road. After about 1 mile on Frontage road, turn right onto Booth Falls Road. Follow Booth Falls road for about 1/4 mile until it terminates at the trailhead parking area. Space is limited and the trailhead parking likely fills early in the day. The trailhead is near a residential area so please be courteous of those living in the vicinity.
The Hike: Booth Creek Falls Hike
From the trailhead, the trail starts at a steep incline as it follows the course of Booth Creek and passes through the aspen forests and glades of wildflowers that make this part of Colorado famous. In the fall, the changing leaves of the aspens make this hike a favorite. The trail continues on this steady ascent for the first mile, then becomes more gradual.

At around 1.8 miles be on the lookout for a trail sign indicating a side-trail for Booth Creek Falls. You may opt to view the falls from the overlook or proceed down the social trails for a closer experience of the falls. Exercise caution, however, because the area around the falls is steep and social trails are not maintained. As with all trails, conditions can change quickly after rains and weather.
Tips & Resources for Hiking Booth Falls Hike
- TIP: The trailhead may not be directly visible from the parking lot, so walk up the road and find it. It will be located just past the gate.
- TIP: Hike further up the trail to Booth Lake. This adds 2.4 miles (round trip).

Parking & Trailhead Information for Shanahan Ridge Loop Trail
The Shanahan Ridge Trailhead is located just along Lehigh Street south of Boulder. From US 36, follow Table Mesa Drive West to its intersection with CO 93. Turn left onto 93 and follow it for less than a mile. Turn right onto Greenbriar Boulevard which eventually becomes Lehigh Street. The trailhead is on the left/southwest side of the road and marked by a trail post and trash receptacle. There is actually no parking lot because the trailhead is located in a residential area. Because of this please exercise extra care and respect for the residents as you park along Lehigh or adjacent streets. Be aware of city parking signage.
The Hike: Shanahan Ridge Loop Trail
The Shanahan Ridge loop is best hiked clockwise in order to gain the best views of the Flatirons and surrounding countryside. Going left on the first junction will take you onto a connector trail that will next intersect with the South Fork Shanahan Trail. This trail begins with a gradual ascent which becomes more demanding. If you are acclimatized to the altitude and hike a fair amount, you'll find this segment easy; but beginner hikers and those of us who are not in the best of shape will find this a moderately demanding trail.
Continue on the South Fork Shanahan Trail for about 1.8 miles as it weaves through ponderosa forest and opens out to captivating vistas of the Flatirons. The trail will terminate at a junction with the Mesa Trail. Follow this trail North (right) as it winds along the base of the Shanahan Ridge of the Flatirons.

After approximately a 1/2 mile on the Mesa trail, it will intersect with the North Fork Shanahan Trail. Taking a right onto the North Fork Shanahan leads backdownhill for about 1.3 miles to the trailhead.

Parking & Trailhead Information for Tarryall Falls Hike
From Denver, take HWY 285 South to Jefferson. In Jefferson, turn left onto CR77 and continue for about 17 miles. The parking pullout is on the southern tip of the reservoir on the right-hand side of the road. This is about 1hr 45 min drive.
From Colorado Springs, take US 24 toward Divide. At 5.4 miles west of Florissant turn right to Tarryall Road / CR 77. Continue on CR 77 for about 24 miles. This stretch makes for a beautiful drive, especially just before sunset when the Tarryalls are lit up all pink and orange. Just after mile 24, there will be a pullout parking area on the left side of the road alongside the reservoir. The hike description below begins at this parking area. This is about a 1hr 30 min drive from Colorado Springs.
The roadside viewing area is easily accessed by turning on to Turner Gulch Road. The parking area is located on the right-hand side of the road soon after turning onto Turner Gulch road.
The Hike: Tarryall Falls Hike

It's less than a 1/4 mile jaunt from the parking area to the waterfall, but be aware that the trail winds through some rocky and loose terrain on this unmaintained trail. The trail begins on the gravel path that heads down toward the reservoir then descends to a footbridge spanning Potato Gulch, a small canyon that serves as an overflow from the reservoir back into Tarryall Creek. I've marked the trail on the map above, but this is intended for general reference only. Take care as you navigate the trail as it winds through the rock on the other side of the footbridge. The path will lead to the top of the waterfall, then eventually down to the base of the falls. This area is not recommended for pets or children and if present should be supervised.

As mentioned in the driving directions above, the stretch of road between Tarryall Reservoir and Lake George is one of my favorites for sunsets. Like the Flatirons of Boulder, the Tarryalls have a pink and orange hue but showcase deeper reds, especially at dusk. When the sunlight hits the rock, the mountains seem to come alive.
Hikers coming from Denver can make a day of it by first visiting the trails along Kenosha Pass, then driving to Tarryall Falls. From there, drive South on CR77 to Lake George, taking in the Tarryall Mountains until you come back out to HWY 24. Follow Highway 24 South to visit Rainbow Falls in Manitou Springs. Grab a bite to eat in Manitou or Colorado Springs, then stop by and visitHelen Hunt Falls. All three waterfalls in this driving loop require very little hiking. Finally, take Interstate 25 North back to the Denver area.

Parking & Trailhead Information for Ridgeline Open Space
From Denver, follow Interstate 25 south to Castle Rock and take Exit 182 and go west on Wolfensberger Road. Turn right onto Coachline and follow this until to Ridgeline Open Space Trailhead (on the left-side of the road). There is a restroom and map at the trailhead. Alternatively, hikers can park at Bison Park in Castle Rock and access one of the several neighborhood access trails that lead into Ridgeline Open Space.
The Hike: Ridgeline Open Space
Ridgeline Open Space is one of our family's favorite places to hike because it's right in our backyard here in Castle Rock. The residents of Castle Rock also use the 13.4 miles of trail for trail running and mountain biking. It's quite a labyrinth of trails, but because it's located right in the heart of a residential area, it's hard to get lost (if you stay on the trail). There are maps posted at several junctions and trailheads along the network in the case you need to reorient yourself. Or print the map from the link above and bring it with you.

Our approach is usually to go up to Ridgeline for an afternoon and see where the trails take us. You'll likely encounter mountain bikers along the trail. Most are locals and are very considerate of hikers. Less considerate are the rattlesnakes. I've yet to run into one, but my neighbor was stopped short by a rattler recently while trail running. Rattlesnakes are only aggressive when threatened, but they are easy to stumble upon because they are so well camouflaged. So, keep your eyes peeled as you hike. Mountain Lions also frequent the area--like most trails along the Front Range--because of the plentiful deer population. It's wise to always keep your kids near when hiking and not running up the trail ahead on their own. This is just good practice on any trail, but I mention it because we have seen Mountain Lion prints in the mud on one of the western trail segments.

Ridgeline is aptly named because it is situated above the town and offers great views out to Longs Peak, Indian Peaks, Mt. Evans, Devil's Head to the west, and Pikes Peak to the south. Deer bed down in the grass between the gamble oak and birds flit from tree to tree along the trails.

Tips & Resources for Hiking the Ridgeline Open Space Trail
- Rattlesnakes: Keep an eye out for rattlesnakes that sun themselves on rock and the packed, warm surface of the trail.
- Hiking with Kids: As always, hike as a group, keeping small children near you. Mountain lions live in the area (as with most front-range hikes), and the sight of a small creature running alone on the trail can signal a lion's prey response.
- Sunscreen: This hike is 100% exposed to the sun's rays, so be sure to wear a hat and apply that sunscreen.

Parking & Trailhead Information for St. Vrain Mountain

From Denver, take Interstate 25 to either 36 or 66 to Lyons. In Lyons, follow 7 to Allenspark. In Allenspark, turn left onto Ski Road - FR-107. This will be marked with a street sign and a home-crafted sign made out of an old pair of skis. Follow this dirt road as is weaves through Allenspark then a series of dispersed cabins for about 2 miles until the road terminates at the trailhead. There is parking for only about 8 vehicles at the trailhead. There is additional parking along the road, but make sure that you're not blocking cabin drives or tearing up the roadside. You may have to park a ways back down the road if crowded. I hiked this on the weekend and the lot was full around 8 AM. There are not restrooms or potable water at the trailhead.
The Hike: St. Vrain Mountain Trail

The hike begins in the shade of aspen, spruce, and lodgepole pine forest. This first segment is easy and gradual, getting steeper as the sounds of distant St. Vrain Creek grow louder and closer. Wildflowers become more prevalent and soon the trail begins to follow right alongside the course of the creek.

Then the switchbacks begin. I hiked this in late-May after a Winter when our snowpack was below normal. So it was snow-free until around mile 2. From about mile 2 to mile 3, intermittent snow covered about 3/4 of the trail. I didn't bring snowshoes but had it been early May, I definitely would have needed a pair. Trekking poles were essential for negotiating the trail and to keep from post-holing up to my waist. It could be done without poles, but I'd definitely recommend having them.

At treeline, things open up to blue skies and high-country tundra brightened by the many colors of summer wildflowers. In early-May, these were just beginning to bloom. However, come mid-June, the creek alongside the trail and these upper reaches of high-country should be replete with wildflowers.

Once you crest the saddle, the views are outstanding. To the Northwest, the entire Wild Basin of Rocky Mountain National Park opens up before you. To the North, you'll find Meadow Mountain, elevation 11,632'. I met a local from Allenspark along the trail and he said the views from the summit of Meadow Mountain rival those of St. Vrain because of the perspective looking down into the Wild Basin area.

At mile 3, the trail enters Rocky Mountain National Park. From this point, I could see a faint trail in the snow leading up the rounded ridgeline of St. Vrain Mountain. It's about a 1/2 mile hike from the main trail to the summit with about 700 feet of elevation gain.

Below is a photo of the map found at the trailhead. I've added a dark-black dashed line to indicate the trail that goes from the junction with the Rock Creek Trail to the summit. The lighter-grey dashed line indicates the path hikers were taking across the snow to the slopes of St. Vrain Mountain. Be sure to hike on durable surfaces (snow, rock, trails) on the summit approach to protect the fragile tundra environment.

- TIP: Trekking Poles are a must on this trail. They will be especially helpful to negotiate the snow that covers the upper reaches of the trail in late-Spring through early Summer.

Parking & Trailhead: Butler Gulch Hike
The Trailhead for Butler Gulch is about 1 hour West of Denver via Interstate 70. Take the exit for Hwy 40/Winter Park (easy to miss) through Empire (be alert for reduced speed limit) up to where US 40 makes a sharp bend to begin climbing up the mountain toward Berthoud Pass. Just before this turn, there is a left-hand turn to take for the Henderson Mine Road. Follow Henderson Mine road for about a mile. It will pass the mining operation and the parking area is just past the mine on the left. The main parking area is the first one you will encounter and it's large. A smaller one is about .25 mile up the road (the road is 4WD after the first lot) is small and fills fast. We recommend parking in the first lot as it is maintained and this will prevent damage to the trailhead.
From the parking area, hike the 4WD road for about 1/4 mile to where the trail splits. There should be signage here at the fork indicating the Jones Pass Trail goes to the right, and the Butler Gulch Trail goes to the left. Soon, the trail begins to climb through mixed forest of spruce, fir, and aspens. After approximately one mile, a mountain stream nears the trail, forming a quaint meltwater waterfall (right side of trail). Soon, the trail emerges from the trees into a landscape of snow-capped mountains. This bowl will be replete with wildflowers in the early weeks of Summer. At this point, hikers are exposed to the elements, and during the Summer months, lightning storms can come up without warning in the afternoon. So, keep an eye on the sky. Winter travelers should be alert to avalanche conditions. Here in the bowl, the trail has come to about 2.5 miles and a hike back will make this a 5-mile round-trip adventure. Hikers can add a strenous hike up the nearby ridgeline to gain panoramic views on the Continental Divide. When I hiked this in April of 2016, tracks were evident that led past the remains of old mining equipment along the ridge. At the top, the views are absolutely beautiful. It's a great place to take in hundreds of miles of changing aspen trees in the Autumn. The trail map link for Butler Gulch in this post is not the best. Because of this we recommend The Latitude 40 Summit County Trails Map.

Parking & Trailhead: Bear Canyon Loop Trail
The National Center for Atmospheric Research (NCAR) Trailhead is located about 40 minutes North of Denver. From Denver, follow U.S. Route 36 to Boulder. Take the exit for Table Mesa Drive and follow it West. It will wind through a neighborhood to the end as it winds through the neighborhood and past Bear Creek Elementary School. The road will turn into the Drive for NCAR which winds up and around to a large parking area at the lab.
The Hike: NCAR Bear Canyon Loop Trail
From the NCAR Parking area, hikers can pick up the NCAR trail just West of the main entrance to the building. The trail heads West, over a small ridge, past a water tank, then to a fork in the trail. Both the left and the right fork are considered the NCAR trail and both will lead to the Table Mesa Trail--but the left fork is shorter. At approximately 0.7-mile into the hike, the NCAR Trail will intersect with the Table Mesa Trail. Straight through takes hikers up on a 0.8-mile hike up to Mallory Cave, but for this loop hike, the correct way is to go left/South onto the Table Mesa trail. This first stretch provides some incredible views of the magnificent Flatirons Formations of Boulder. This trail segment heading south goes in and out of a forest grove, then the trail comes to its second important intersection.
At the Bear Canyon Trail intersection, take a left onto the Bear Canyon Trail which follows Bear Creek as it descends East. At about 1.5 miles into the hike, you'll encounter another fork. You can cut off about 1/4 of a mile of the trail by taking the left-hand segment. But the right-hand trail provides more pleasant scenery along the creek. The trail will near a neighborhood then bend to the North. This straight 0.7-mile stretch follows along the Eastern boundary of NCAR. Eventually, it meets up with the NCAR trail, which will lead back on a 1/2 mile stretch to the parking area.
Tips & Resources for Hiking the NCAR Bear Canyon Loop
- Wildlife Aware: Like many of the trails in the Boulder area, keep alert because mountain lions and black bears frequent the area. Know what to do if you encounter a Mountain Lion or a Black Bear.
