Capitol Peak Route Guide | The Most Dangerous 14er in Colorado

Capitol Peak is notorious among the Colorado fourteeners for being the most difficult of the fifty-eight peaks to ascend. The challenges on this mountain abound. There’s a long, 8.5 mile approach hike requiring backpacking skills. The rock is loose and rotten, making rockfall risk significant. And then there’s the infamous Knife’s Edge ridge between Capitol Peak and K2. This mountain has taken many lives over the past several decades. Do not attempt to climb it without serious preparation and a lot of scrambling and climbing experience. Get started with your planning below at your own peril with my Capitol Peak route guide.

Capitol Peak Route Guide - Northeast Ridge

You can take either the Capitol Creek Trail or the Capitol “Ditch” Trail to reach Capitol Lake. This Capitol Peak route guide uses the increasingly popular Ditch Trail alternative.

At the west end of the trailhead parking area, you’ll find the signed ditch trail, which follows a water ditch. Continue along this ditch for about 1.2 miles until you reach a junction at 9,500 feet. Cross the ditch, then keep hiking along the trail. Move through the forest for a bit and cross a stream before entering the Maroon Bells Snowmass wilderness. Keep going to reach a wide-open area. Keep along the hillside for a mile and half before moving down to a meadow near the creek. Move left, cross this stream, and cross the main Capitol Creek trail on the other side.

Turn right onto the Capitol Creek Trail. Cross several streams, climb a hill near 10,800 feet. Eventually cross to the west side of Capitol Creek, near 11,000 feet. At 11,400 feet, turn right to gain the basin below Capitol Lake. I recommend camping in sites below the basin to the right of the trail.

Near 11,600 feet, just below the lake, take a left on to a thinner trail to keep moving southeast toward the saddle between Mt. Daly (a thirteener) and Capitol Peak. Hike up 900 feet to reach the saddle. The easy hiking ends here.

From the saddle, is’s an option to turn right and climb south up the Class 4 ridge, but the the easier, standard route described here in my Capitol Peak route guide involves circling around the east side. From the east side of the saddle, begin traversing south. Be careful and move slowly, making a point of not losing elevation as you cross several gullies. The initial section can be confusing to some people as it does not have one obvious trail.  (Don’t climb the steep terrain/cliffs up to your right). After traversing .25 mile, the route becomes more obvious – continue south across talus.

Around 12,700 feet, angle up to the right where you’ll see “K2” to the southwest, another thirteener. Follow the cairns or take your own line up rocky terrain to reach K2. You don’t have to summit K2, but I think it’s worth the effort because of the wonderful view of Capitol Peak. 

If you do climb K2, you can descend around 50 feet of class 3/4 terrain off its west side to get back on the route. The easiest way (requires careful maneuvering on loose rock) around K2 is to turn right just below the summit and move around to the west. Once on the west side, Capitol’s northeast ridge comes into view. Drop into a notch and climb onto a rock tower at the start of the ridge.

The rest of this route has a lot  of exposed climbing along the ridge. This is a really good spot to take a serious look at the weather and decide whether or not to keep going. While the summit isn’t far away, the remaining climb is time-consuming and a dangerous place to be in bad weather. If you see storms on thee horizon, descend and come back another day.

From the first tower, scramble on the ridge for a time until you reach the infamous Knife Edge. This is the crux of the Capitol Peak route guide. It’s actually a veery short section of the ridge, but it”s very exposed and requires concentration and comfort around steep cliffs. If you are worked up by exposure, this area may really wreak havoc on you. Scramble along the crest or walk along the left side while holding onto the ridge. The last portion of the knife is very “sharp” so the easiest way around is to walk along the left side while holding the top.

Beyond the Knife Edge, scramble on or along the ridge towards the summit. Roughly 1/10 mile after from the Knife Edge, find a notch with a steep gully down to the left. Cross the notch and start climbing along the left side of the ridge. Above 13,800 feet, the best and easiest route is on the upper east face and not on the crest of the northeast ridge. Begin to move left away from the ridge crest to climb steep rock and reach a small ridge on the upper east face. Take a right to ascend less-loose rock to reach the summit ridge.

Enjoy your views from the summit of Colorado’s most dangerous and difficult fourteener, and enjoy your accomplishment. Be sure you head down with plenty of time to reach tree line before afternoon storms become a hazard. Many people have died descending Capitol Peak because they took a gully shortcut, including 5 people in 2017. You MUST take the standard route back to the lake. There are no short cuts.
