Looking For An Amazing Adventure? Book A Hiking Tour in Rocky Mountain National Park
East and West Desolation Peaks epitomize the joys of the lesser-known locations in Rocky Mountain National Park. They are far from established trailheads, require off-trail navigation to get to, and, because they sit hundreds of feet lower than the more obvious and well-known Mummy Range, only attract a handful of backcountry enthusiasts each year. However, East and West Desolation contain some of the most interesting and enjoyable scrambling I’ve found north of Trail Ridge Road. Despite falling short of 13,000 feet, these mountains are serious, and the scrambling required to attain their summits is substantial. If complex route navigation and scrambling options on relatively stable rocks are things you seek out, the Desolations may be the perfect addition to a Rocky Mountain adventure.
- 2021 Status: Temporarily closed; check Fire Closures here.
- Popularity: Low
- Technical Rating:
- West Desolation: Class 3 with substantial route finding
- East Desolation: Class 4 via the standard route, Class 3+ via cave passage
This article utilizes three separate rating systems: Difficulty, Popularity, and a Technical Rating indicating the hardest move or set of moves encountered. The technical rating employs the Yosemite Decimal System.
- Easy: less than 5 miles, less than 500 ft. of elevation gain
- Moderate: 5-10 miles, 500-2000 ft of elevation gain
- Hard: 5-15 miles, more than 2000 ft. of elevation gain
- Very Hard: 10+ miles, more than 3,500 ft. of elevation gain
- Low: Large sections of trail all to yourself
- Moderate: Sizeable trail sections to yourself, crowding possible on busy summer weekends
- High: You’ll be seeing people, still a chance for solitude in spring/fall/winter.
- Very High: Almost always busy.
- Class 1: Established hiking trail the entire length of the adventure. Low chance for injury.
- Class 2: Typically involves cross-country navigation, possibly using hands for balance but not required, steeper than Class 1.
- Class 3: Hands and feet used to scale areas, must use hands to proceed (either for balance or to help pull you up a section), increased exposure, a fall could be fatal. Helmet recommended, along with grippy hikers.
- Class 4: Climbing on very steep terrain just shy of vertical, falls could be fatal, hands employed for grip and balance continuously, ropes advisable but scalable without. Helmets are highly recommended, along with grippy hikers.
- Class 5-5.4: Vertical climbing that involves technical rock-climbing moves, exposed, falls likely to be serious or fatal, possible to scale without ropes but only for very experienced veterans. Helmets, grippy hikers, and/or rock-climbing shoes necessary.
- Class 5.5 and up: Not covered as scrambling, full-on rock climbing with ropes, helmets, etc.
The YDS system is widely used in North America but can be quite subjective, so it is not perfect. The biggest differences I’ve encountered between Class 3 and Class 4 sections have to do with slope angle, exposure, and putting weight and pressure on hand grips (4) instead of using hands and feet interchangeably as supporting points of contact (3). It is not possible to climb a Class 4 section without using your hands to pull up some or all of your body weight. Typically, a Class 4 section will also require some type of rock-climbing move, like stemming, where hands or feet are pressed in opposition as if climbing the inside of a chimney. If downclimbing, a key difference is that most people will descend a Class 4 section facing inward, i.e., your back faces the exposure.
Despite the Desolation Peaks seeing little to no traffic every year, the access is fairly simple once Old Fall River Road opens. Please note it usually takes until July every year for Old Fall River Road to open, and it will close after the first heavy snowfall, which frequently occurs between September and October.
From the east, enter the park via US 34, passing the Fall River visitor center. It’s possible to enter via US 36 at Beaver Meadows, but it takes a little longer. The key is to make it Horseshoe Park, where at a large bend in the road surrounded by fields, you’ll notice a road heading west into a deep canyon. Signs will indicate Old Fall River Road and the Endovalley Picnic Area along with Alluvial Fan. Take a right if coming from the Fall River entrance and head west on the long, windy, one-way road. It is a primarily gravel road, so expect 30 minutes to get to Chapin Pass Trailhead.
From the west, enter the park, and traverse Trail Ridge all the way down to its intersection with US 36 (well past the alpine portions). Take a left on US 34 and make your way down to Horseshoe Park. Take a left on Old Fall River Road after seeing signs for Endovalley and Alluvial Fan. Drive up to Chapin Pass Trailhead.
Chapin Pass is close to the alpine but still below it; if you break out of the trees, you’ve gone too far. If this is your first time in the area, the best practice is to go a little slower. Since it’s a one-way road, there aren’t really opportunities to backtrack. The road will follow Fall River for most of the route with the occasional switchback. From Willow Park (a meadowed area frequented by elk), the road begins a series of switchbacks north up the slope. After the third switchback, start paying attention. The trailhead is on the right side of the road, and there will likely be cars parked alongside the road on the left- and right-hand sides. Carefully find a place to park (there are no guardrails) and find the trailhead leading north to start your journey. It is about 7.7 miles from Endovalley to Chapin Pass.

- Free or close to free: but a little farther (if you’re willing to drive)
Due to the Cameron Peak fire, areas to the north and west of the main Mummy Range crest, including the Desolations, are temporarily closed. It is unknown when they will reopen. Please click here to assess the status of the area, which includes access to the Desolations. I’m releasing this review a year after I scrambled there for multiple reasons: to showcase an awesome scramble, to point out how devastating fire damage can be in mountainous terrain, and in the hopes that the area will reopen to foot traffic soon.
The majority of this hike is above treeline, so you really need a good weather day. From certain points on the trail, it’s possible to bail into the Chapin Creek drainage to find tree cover, but you will have to climb back out of it to exit the area. Bring sunscreen, lots of water, and know the signs of altitude sickness should they surface.
Geographic orientation is also a component of this hike as a lot of it occurs in a trail-less environment and on seldom climbed peaks. Since the majority of the hike is above treeline, orientation isn’t very difficult, but in inclement weather, the ability to orient is a must. Take care when traversing across the alpine, the vegetation is very sensitive up here, and off-trail hiking leads to a higher risk for twisted ankles. Hikers with good ankle support are much better for off-trail travel than low-rise trail runners.
Forecasting is a great way to set yourself up for success when entering seldom-traveled areas. While long-range forecasts in the mountains are pretty fickle, checking a few sources up to the minute you leave for the trailhead will help you get the latest and greatest weather predictions. Due to its relative proximity to the Alpine Center, I’d start by checking the weather for Trail Ridge. From there, I’d utilize mountain forecasts for Mt. Chiquita and Ypsilon Mountain, which you’ll pass on your way to the Desolations. Pay special attention to temperature, thunderstorm chances, and wind speed, as the Front Range alpine is notorious for experiencing persistent and powerful wind gusts.
Please note: The Cameron Peak Fire exploded in growth on the day I hiked the Desolations in August 2020, so the smoke will impact some pictures. It makes the name Desolation seem very appropriate.
There are still many places in Rocky Mountain National Park to get away from the crowds; this is one of them. Chapin Pass Trailhead is the main way to access a large portion of the southern Mummy Range, including the summits of Mt. Chapin, Mt. Chiquita, and Ypsilon mountain. You are likely to see other cars at the trailhead, but once you get off the Mummy Crest, solitude will reign.
Begin by heading north on a wide trail to the Chapin Pass saddle. There, look to the right and find a trail, initially heading east. Follow this trail as it meanders toward treeline and up the slopes of Mt. Chapin. At various points, you’ll be able to look northeast and see the profiles of your targets.
Once you get to the base of Chapin’s double humped-summit block, two strong hiker trails traverse the mountain on its’ left-hand side. Take the higher or right-hand variation.
If you want to tag Chapin, the easiest and quickest access is to traverse around to the next saddle between Chapin and Chiquita. Then, pivot right and follow cairns and an intermittent hiking path to the summit.
From the saddle between Chiquita and Chapin, the most obvious hiking trail continues northwest near the ridge crest, getting close to but ultimately skirting around the summit of Chiquita. The detour to touch the top is minimal. It’s from the saddle between Chiquita and Ypsilon that you want to start thinking about off-trail.
Proceed towards Ypsilon initially, gaining roughly 100-200 feet before beginning a traverse left into the alpine. The extra few hundred feet from the saddle is necessary. If you begin your traverse from the saddle and maintain your elevation, you’ll run into loose and complicated rocky terrain. Starting the traverse a little higher removes that obstacle.
As you round the bulbous northside of Ypsilon, you’ll be able to see the more clearly defined summits of West and East Desolation. East Desolation’s summit is quite distinct and can be used as a geographic marker.
Aim for the saddle between Ypsilon and the north running ridge that leads to the Desolations. You may lose some elevation here, but it’s worth it to avoid unnecessary difficulties below you.
From the saddle, orientation is fairly simple. Head north across multiple mini high points, traversing around harder sections as they appear.
The high points are generally all talus, so watch where you plant your feet and always check to make sure rocks aren’t going to move before putting weight on them. Your pace will inevitably slow during this section, but since you’re now decidedly off-trail and moving farther from help, safety has to come first.
After some ridge walking, you’ll draw even with West Desolation. Turn to your right and assess the first parts of this route. Both Desolation peaks are off-center from the main ridgeline.
Proceed east towards the rocky buttress of West Desolation as the hike becomes increasingly scrambly.
Scramble around the Double Stacks on the ridge until you are directly in front of the vertical West Desolation summit block.
This is where the whole route gets into solid Class 3 territory and becomes much more interesting.
If you’re looking directly at the rock walls in front of you, skirt right, hugging the base of the cliffs until you see a large, flat-topped boulder that looks like a hardcover book.
Ascend a crack to the left of the Book Rock, and you may find a cairn on top.
From here, move to a broken, south angled slab.
Traverse the bottom of the slab until finding a large crack; ascend it to the top of the slab.
Traverse right across the top of the slab, finding the path of least resistance and dispensing with some small Class 3 moves along the way.
While initially vertical, the rock walls to your left will eventually break into a series of climbable gullies.
Wait until you find a Class 3 chute with good foot and handholds; there are multiple options. The first Class 3+ option is what I climbed and looks like this from the bottom.
When sighted, turn left and climb up the block toward the summit plateau. After this fun Class 3 climb, you’ll be deposited on a larger flat summit area. The true summit is a little west and higher than where you are. Stay on the slanted slabs and work your way towards the summit rib. A few easy third-class moves will get you to the top. The summit is a rock finger sticking up, touch it, and you’ve climbed West Desolation.
From the summit, take a good look at the intimidating profile of East Desolation. You’ll be up there soon! The climbing on East Desolation is fairly straightforward, but you have to get there first, and the difficulties on West Desolation are not over yet.
Drop down from the summit rib to the summit plateau. Hike east until sighting a path to the left that drops down.
Carefully drop down and pass between two evil-looking gates that guard either side.
Don’t rush; the rock features here contain deep openings between them that a foot or leg could plunge into. After passing between the gates, turn to the right until you’ve matched the ridge to East Desolation. From here, you should be able to see the Wave Wall, a striking and obvious rock feature that frames the left side of your path. Carefully rock hop through this section.
On the other side, the Wave Wall begins to push you into a southeast direction. If you stay on this trajectory, you’ll drop off the ridge and find no easy passage forward. Crank your head to the left and look for a weakness in the Wave Wall, which you will ascend into.
Once you’ve climbed over the wall, hook right and follow the easier ridgeline down to the saddle between the two summits.
Despite only being 3rd Class, the orientation component is critical. It’s easy to get off route here, so keep your head on a swivel. From the saddle, begin a moderate scramble up to the pointy summit boulders. There are multiple ways to do this, generally speaking, heading a little left of the ridgeline is easier (Class 2), but the ridgeline contains the best and grippiest rock. You could stick to the ridgeline and ascend low Class 3 rocks as an alternative route. Once you arrive underneath the rock fortress that guards East Desolation, it’s worth taking a good look at the most difficult moves on the standard route.
You’ll start on the ridgeline, squeeze up a crack, and into a notch with a huge cliff on the right-hand side to keep you company. You have to climb a crack system between two angled rocks to get through.
This is Class 4 territory; any fall here will funnel you into the open hole leading south, dropping you hundreds of feet onto sharp rocks. The moves themselves aren’t impossible, but do yourself a favor and don’t look down.
After spending some time exploring the area, I managed to find an alternative way to bypass the Class 4 section. The summit rocks on East Desolation are massive, and all lean against each other in various ways. The gaps between the rocks are open, which can lead to a small cave workaround.
Be warned: if you are over six feet tall, this may be an uncomfortable set of moves. For fun-size individuals, you should be able to find a cave entrance, work your way into it, and before it ends, turn to the right. Crawl forward into another slot and carefully stand up.
From here, turn around 180 degrees until facing east and sight a 10-foot angled rock section that is on the higher end of Class 3 but doesn’t quite feel like a 4.
Exposure is still pronounced, so focus on one move at a time. Once you clamber up, the summit is only a couple of feet away. Sit down, relax and enjoy this exposed, blocky, and altogether remote summit.
The view back to West Desolation is fascinating; the entire mountain looks like a geologic wave rising from right to left before crashing down into a compressed chaotic mess.
An added benefit of this perspective is that you can make out the features you encountered descending West Desolation.
From the summit of East Desolation, edge your way back down the angled rock section to a mini notch. To reach the Class 4 section, continue up and over the next rock. If you want to retrace your ascent through the secret passage, step into the notch, turn 180 degrees, duck down and work your way forward under the section you just climbed down. After a few seconds of ducking and shuffling, break left around the bottom edge of another large rock and work your way to the secret passage entrance. From here, you can descend on easier terrain to the saddle between the peaks, using either the ridge crest or the slopes to the right of it.
At the saddle, survey what lies ahead.
You’ll either travel on the ridge crest (light Class 3) or to the right of the crest (Class 2), rising around or over a couple of ridge bumps. Remember, you’ll need to get onto the left side of the ridge crest, which turns into the Wave Wall. If you’re worried about where to climb back over, it’s best to stay close to, or on top of, the ridge crest, checking weaknesses as you come across them.
Once you drop down into a trench with the Wave Wall on your right side, continue ascending.
After the Wave Wall ends, ascend between the two Synyster Gates, and rise back up to West Desolations summit plateau.
Work your way to the left edge of the summit plateau and find the 3rd Class gully you used to climb up. Descend until you are at the base of the summit block. This is a short but enjoyable descent.
Break right and walk along the base of the summit cliffs until you see the angled slab to your left. Find the large crack to your left, carefully move down to the edge of the slab and take another right, paralleling the slope. With a few last Class 3 moves, you’ll pass over the flat-topped Book Rock and drop back to easier terrain. Continue to walk the ridgeline back to its confluence with another. Where the ridges meet, the scrambling ends. From there, retrace your steps south across the various ridge points.
For an added variation, when you reach the saddle with Ypsilon, descend down a west-facing gully to a series of meadows.
Proceed north, contouring the land and passing through several meadows with bouncy tussock-like grass.
Eventually, if you keep your northward bearing, you’ll rise up the slopes of Mt. Chapin and intersect a strong hikers trail. Take it to the right until it joins with your original ascent route.
Despite its relatively modest length, this is no walk in the park. Once you leave the main Mummy Range crest, it’s all off-trail, and the scrambling is more or less continuous up and over West Desolation. The final push up the summit block of East Desolation is also challenging and adrenaline-pumping. Keep in mind that the main access point to these peaks is unavailable when Old Fall River Road closes, so the season to tag these mountains runs from roughly July-September.
This kind of adventure will not appeal to all outdoor recreationists. You need to be competent in off-trail travel, have experience tackling remote peaks, and understand the risks of alpine scrambling. The peaks are a wonderful and well-hidden area of the park, so for those looking to increase their scrambling experience in a place likely to grant solitude, consider visiting the Desolations.
