Original Trip Report

The following trip report is copied (and updated) from another page for my 2014 trip to RMNP (my second ever trip to RMNP, before I lived in Colorado). My original 2014 trip report also includes a climb of Ariana on The Diamond and Sykes' Sickle on Spearhead.

Intro

Climb Longs Peak via Keyhole Route (2nd/3rd) solo. This was a great way to acclimatize to the altitude and to familiarize myself with the mountain as well as get to the top of the highest summit in the Park (and a 14-neer!).

Trailhead to The Boulderfield

2nd
Hike a bit over 6 miles from the Longs Peak Trailhead to The Boulderfield. The Boulderfield is a broad rocky expanse on the north shoulder of Longs Peak below The Keyhole.

The Keyhole

3rd
The Keyhole is a pronounced notch in the northwest ridge of Longs Peak. The Keyhole is the key to the route, allowing access from the east side of Longs Peak to the west side.

The distance from the Keyhole to the summit is about a mile but it is a time-consuming mile with lots of route-finding, exposure, and scrambling. From here, the route spirals around the west and south sides of the mountain to the summit. The route is marked at crucial spots with painted yellow and red bull's-eyes. 

The Trough

3rd
The Trough is a long gully on the back (west) side of Longs Peak that extends all the way down into Glacier Gorge and it passes by the upper reaches of Longs Peak 0.3 miles from the The Keyhole. The Trough is often filled with snow and may require crampons and ice axe in early summer. Climb The Trough for 550 feet to the west ridge of Longs Peak.

The Narrows

3rd
The Narrows is a slender shelf located at the top of The Trough. Scramble across on broken ledges, then around a rib to the base of The Homestretch.

The Homestretch

3rd
The Homestretch is a steep ramp on the south face of Longs. It leads to the summit. It can be a bit slick at times.

Summit

14,259 feet
The top of Longs Peak is 14,259 feet. The highest summit in RMNP. Enjoy the view! And the crowds. Hopefully not a thundershower.

Intro

Longs Peak, one of Colorado's most popular Fourteeners, is usually climbed by the Keyhole Route. This classic route involves moderate hiking on a trail and third-class rock scrambling. The route is generally free from snow from early July to mid-September. During the rest of the year, the route is a technical mountaineering climb with snow and ice, requiring an ice axe, crampons, and rope. The route, spiraling around Longs Peak, travels over 7 miles from the trailhead to summit, making for a 14.5 mile round trip with about 5,100 feet of elevation gain/loss. It is best to climb early, so as not to get caught in an afternoon thunderstorm, common in the summer in the Rockies.

I had first climbed the Keyhole Route in August 2014, on a brief visit to RMNP. The following day, I climbed The Diamond, a sheer rock wall on the east side of Longs Peak. My enthrallment with RMNP during this trip set the seed for my eventual move to Boulder, Colorado in June 2019.

Eight years after I first climbed the Keyhole Route and now living 1 hour from the Longs Peak Trailhead, I finally ascended Longs Peak via the Keyhole Route for a second time (I had ascended Longs Peak numerous times after climbs on The Diamond, just not via the Keyhole Route). My car-to-car time was 6 hours and 20 minutes (18 minutes slower than my car-to-car time in 2014, when I had been younger, faster, and quicker on the descent—a major knee surgery in 2020 has made me a bit more cautious on descents). Also, I used the shortcuts, which shaves off some minutes each way. I was back home in Boulder shortly after noon. Much better than a morning run!

The following trip report gives time stats and photos from my 2022 climb of the Keyhole Route. Below this I include my trip report for my 2014 climb of the Keyhole Route.

2024 Update: In late March 2024, I did my first spring ascent of Longs Peak, via the Keyhole Route. See the next trip repor ton this page.

Intro

In February, I had joined Lisa Foster on a winter ascent of Longs Peak via the Cables Route on the North Face. This marked my first winter ascent of Longs Peak, and Lisa's 50th month (!) in a row summiting Longs. I had a blast, and I told her to keep me in mind for any future Longs Peak ascents. So I was psyched when in late March, she called me and asked if I was interested in making a summit bid on Longs the next day. She had been up there the previous day but had turned around at The Trough due to deep snow. But she wanted to know if I was interested in an early spring ascent of the Keyhole Route with lots of trail-breaking. I was all in. This was worth a PTO day for sure.

This was my 20th time reaching the summit of Longs, and my first spring ascent. I have climbed Longs Peak via the Keyhole Route more than once in the summer (see other trip reports on this page), when it is merely a 3rd class scramble, but in the winter/spring it is an entirely different experience. To be honest, I almost bailed out when we reached the Boulderfield, when my hands became so cold and useless that I was worried about frostbite. I had two electric and two chemical hand warmers per mitt too! But Lisa offered to exchange mittens with me for awhile, which was a lifesaver. I rallied and we continued. I am so glad we did. (Thanks Lisa!)

Our entire adventure took just over 17 hours car to car. The way up took 12 hours and the way down took just under 5 hours. Most of the terrain was snow-covered, and the snow was deep at times, slowing down the ascent significantly. We wore snowshoes from treeline to The Keyhole, and crampons from The Keyhole to the summit. It was a gorgeous day and I reveled in every bit of it (except maybe the cold hand episode).

The following page gives overlays and photos from my first spring ascent of Longs Peak. Enjoy.

(And I am going to buy a pair of mittens more capable of keeping my hands warm at 12,000-14,000 feet in the winter. A couple of hundred dollars is worth keeping all 10 digits.)

The Keyhole

3rd
The Keyhole is a pronounced notch in the northwest ridge of Longs Peak. The Keyhole is the key to the route, allowing access from the east side of Longs Peak to the west side.

The distance from the Keyhole to the summit is about a mile but it is a time-consuming mile with lots of route-finding, exposure, and scrambling (or snow travel in spring/winter/fall). From here, the route spirals around the west and south sides of the mountain to the summit. The route is marked at crucial spots with painted yellow and red bull's-eyes (mostly buried on the day of this trip report).

The Trough

3rd
The Trough is a long gully on the back (west) side of Longs Peak that extends all the way down into Glacier Gorge and it passes by the upper reaches of Longs Peak 0.3 miles from the The Keyhole. Climb The Trough for 550 feet to the west ridge of Longs Peak. Even in the summer, The Trough is often filled with snow and may require crampons and ice axe. In the spring ascent in this trip report, we booted up through sometimes deep snow. It was a good workout.

Summit

14,259 feet
The top of Longs Peak is 14,259 feet. The highest summit in RMNP. Enjoy the view! We had the summit to ourselves.
