Devils Thumb Trail Professional Reviews and Guides

"The Indian Peaks Wilderness Area northwest of Denver is one of the most popular in the state, and this loop is a big reason why. Hikers can look forward to two long, verdant valleys, a couple of outrageously beautiful mountain passes, a stretch along the Continental Divide Trail with all-over views, and three lakes strung out along the hike like pearls, each offering a number of great campsites.

Add in some plump hillsides glowing with colorful wildflowers and this wilderness is a beauty indeed, but it is also heavily used due to proximity to swelling population centers along the Front Range. Camping requires permits, and a late start, especially on weekends, will guarantee some additional mileage just hiking to the trailhead from a distant parking place. So choose a beautiful weekday, get here early, and discover why this area is such a Colorado gem."

"This is a wonderful hike up to beautiful Jasper Lake. Jasper Lake is a nineteen-acre glacier and stream-fed alpine lake situated in a dense spruce forest below the jagged summit of Devils Thumb Peak and the curving ridgeline of Mount Neva. Expect to see abundant wildflowers, alpine lakes, and spectacular views of Devils Thumb Peak and Mount Neva. Snow stays on the trail above the Diamond Lake Trail well into late June.

Cutthroat, brook, and brown trout can be found in the clear waters of the lake; bring a fishing rod along. Trail conditions: The lower portion of the trail is maintained and sees heavy use during the late summer months. The upper portion of the trail is rocky, wet, and covered with snow during the late spring and early summer months."

"The vistas are forever on this magnificent ridge walk along the spine of the continent. Here is a delightful, scenic ridge walk, above timberline, between two high passes on the Continental Divide Trail. The vistas are forever! Vehicles are forbidden on the trail, and dogs must be leashed in this designated Wilderness Area.

The hike begins at the town site of Corona, which had a railroad station, hotel, restaurant and worker's quarters until abandoned in 1928. The route follows the legendary Continental Divide National Scenic Trail, as it winds its way along the spectacular spine of the continent between Canada and Mexico. The numbers will induce blisters on your feet just thinking about them — 3,100 miles, five states, 25 National Forests, 20 Wilderness Areas, three National Parks. Only about a dozen people undertake the full, six-month journey each year."

"The Devils Thumb rises from the east side of the Continental Divide above Devils Thumb Lake. Two glaciers carved the Devils Thumb column from the Continental Divide. Winds prevailing from the west carried ice-age snow to dump in the shelter on the east side of the Divide.

After it accumulates approximately 250 feet thick, the ice began to flow, carrying away rock frozen in the ice. The rock remaining between these two glaciers is Devils Thumb. Had wind direction permitted another glacier to form on a third side of the column to cut a third wall, Devils Thumb would be what climbers call a horn."

"Devils Thumb Lake is named for a sharp rock spire that dominates the slope above the lake. The Hessie Trailhead is a quarter mile along a road/creek bed that sometimes carries water and always is paved by cobbles hard on even booted feet. The worst parts are bordered by a trail that lifts hikers above this hassle.

High clearance vehicles can make it all the way to the Hessie Trailhead and less-than-abundant parking. A bridge carries hikers across North Fork Middle Boulder Creek. Rather ironic signs near the bridge prohibit vehicles from splashing across the creek and also prohibit parking at a spot blocking an obvious vehicle ford."

Beautiful hike, so lovely I managed to leave behind my blue hat (baseball cap style) and LG Mountain Hardware waist pack! Once I noticed it was gone, I looked for it but to no avail. I think it is somewhere near the top of Devil's Thumb. I'm offering a reward! Please message me with any info.

began the hike from the Fraser side; very nice meadow early in the hike, but we turned around after 1 1/2 hours--the mosquitos got thicker the higher we went, and it began to feel like chinese torture! didn't make it to the top, sadly.

Absolutely beautiful. There are excellent views virtually the whole way. There was still quite a bit of snow toward the top, though. The trail is well maintained and easy to follow.

The dirt road leading to Rollin's pass is an adventure in itself, particularly if you are in a passenger car. My advice: Rent a Jeep! Once you get to the parking area, you are already above the treeline. The trail is very well marked. The first .5 miles is probably the toughest part, zig-zagging up to the ridge. Take it slow, and it is not too difficult. Once you've made it to the top the remaining 4 miles are a wonderful walk through a tundra meadow. The views go on forever in every direction. This trail was my first hike in Colorado, and it was well chosen. The trail was remarkably easy on the feet. The view from the lip of the ridge is daunting, but spectacular. The place is alive with wild life. Little pikas scurry all through the bolder fields, calling to each other in little squeaking sounds. We dubbed them 'the rubber duckies of the rockies'. We also saw a yellow bellied marmet basking kingly on a rock at overlooking the valley. This walk is completely above treeline and exposed to the elements. Do not go if there is threat of thunder and lighting. It is well worth the horrendous drive up the dirt road to get there.

The road to the trail head is reachable by passenger car although it is slow going. Be sure there is low likelihood of thunderstorms the day you go, as you are totally exposed along the entire length of the trail. Also about 0.8 mile after leaving the parking lot the trail splits in two. If you take the upper trail, faint departure from the first, you will find it easier to look over the edge to the east. You should do this several times to catch the close in dramatic drop offs. Do it above Bob Lake, at the point where the Devils Thumb Pass crosses the divide and at Devils Thumb Pass itself, farther on. You won't regret it!
