Long’s Peak


[All: 2 Avg.: 5]


14.5 Miles

Highest Elevation


Lowest Elevation



5,100 ft.


Class 3


Truly a classic route up one of Colorado’s most iconic mountains. The Keyhole route takes you through expansive views of Chasm Lake before shooting across a field of large boulders, through narrow ledges, and ending with a steep hands-and-feet scramble to the summit. The risks are elevated on parts of this route, but there are few better views of Rocky Mountain National Park than from the summit.

Note: This mountain involves serious risks and is not for beginners.

This trail starts at the Long’s Peak Ranger Station [1]. Take the East Longs Peak Trail immediately to the left of the building. About 0.5mi in, split left to follow signs for Long’s Peak and Chasm Lake [2]. Near 1.1mi, keep right, passing a sign for Goblin’s Forest (which is a minor trail to the left) [3]. At mile 2.5/11,000ft, keep left at the fork, continuing toward Long’s Peak/Chasm Lake [6]. The opposing direction will take you to Battle Mountain or to Jim’s Grove, an alternate route to the Boulderfield. At mile 3.2 you will reach the junction for Chasm Lake [11] which has a toilet (privy) and numerous signs to point the way. Ascend to the right for Long’s Peak/Boulderfield. At mile 4.3 you’ll reach Granite Pass at 12,120ft. Stay left at the fork [13]. Near 12,630ft, mile 5.4, you’ll cross a small stream, and a good point to filter water [15]. At about this time, the terrain will be almost exclusively rock, void of trail. Follow cairns to the Keyhole, which should be becoming visible on the lower ridges in front of you. At approximately 12,700ft, a primitive camp site and toilets are found in the boulders [17]. This is approximately halfway through the boulderfield. Seasonal water can be found in this area. At the Keyhole, mile 6.2, a stone shelter can be found just beneath it.

The Keyhole

The Keyhole at mile 6.2 [20] is a serious waypoint that starts noticeably more difficult terrain. Beyond this is very thin ledges, interpretive terrain, summer snow and ice, and class 3 hands-and-feet navigation. Know your abilities and limits, and ,go prepared.

The Ledges

From the Keyhole, the next section is called The Ledges [38-48]. Follow bullseyes (circled in orange in the photos) that are almost always visible from here to the summit. Beyond The Ledges, enter The Trough, and climb it to the v-shaped notch at the top, staying on steep packed dirt and large boulders as you climb. Bulleyes will mark the way. At the top of The Trough, a large boulder stands on the path to your next section. This boulder demands your attention as you make class 3 moves up for about 8-10 feet [47, 48]. Atop this boulder, you’ll be standing on a very exposed and thin ledge that enters The Narrows [48-51].

The Narrows

The Narrows is appropriately named. Its path is about 2-4 ft wide with thousands of feet of exposure off the edge. The Narrows starts with a large rock that blocks its route. You can either crawl over the top, or squeeze to the left of this rock [50-53]. The Narrows will funnel you to a notch similar to the boulders at the top of the Trough, which you must use cautious hands-and-feet moves to get up and over [57]. At the top of this rock, notice the red sign bolted to the rock [58]. It is imperative you search for this sign on your return down. If you start getting a view like photo [60], you have descended too far and the terrain will quickly become dangerous as it cliffs out.

The Homestretch

From here, The Homestretch [65-71] comes in to view. This steep, defined crack in the rock will take you to the summit. Though it looks intimidating, the rock is generally very stable, and bullseyes will mark a route that offers generous holds to create almost a natural staircase. Staying in the crack or immediately left of it will offer the best holds in this lengthy class 3 section. This section, like the Narrows, can feel very crowded even with just a few other people on it.

As you top out The Homestrech, you’ll be on the summit [72, 73]. Notice the red sign that indicates your return to the descent.

Getting Down From Long’s Peak

Return down the way you came. Notice the red sign that is at the very top of the Homestretch that indicates where to descend. Descend the Homestretch “backwards” with your hands and feet facing the rock.
