There is additional information about the peak, local regulations, plus additional resources and a frequently asked question section. Have a question? Leave a comment at the bottom of the route guide and we’ll reply ASAP with an answer. Cheers!

Note: Climbing Longs Peak is extremely difficult and risky – more than 70 people have died trying to reach the summit. Do not climb Longs Peak until you have climbed several Class 1 and 2 fourteeners. Give Longs Peak the respect and seriousness it deserves.

The Longs Peak route is a long ascent for a single day. If that’s your plan, aim to hit the trail by 2 am to ensure you are back safe below the treeline before afternoon lightning storms strike. The section of the trail below the treeline is well-built and maintained. You’ll go up a few switchbacks and cross a stream before you approach the tree line. Once you pop out from under the forest you’ll have a great view of Mount Lady Washington in front of you with Longs Peak beyond it (if you can see in the dark).

At the junction to Chasm Junction, there’s a National Park-maintained bathroom you can use. Otherwise, take a hard right here to walk along the slopes of Mt Lady Washington. Your next goal is Granite Pass, where you’ll take a left.

After Granite Pass, climb a series of switchbacks up Mt Lady Washington’s northwest slopes. You’ll probably begin to see dawn during this section. In the boulder field, you will pass your last chance to use a bathroom along with the tents of those who reserved a spot up here for the night. Continue southwest and aim for the Keyhole rock feature. The scrambling will become more difficult and the boulders will get larger as you approach it.

The Keyhole is often a significant bottleneck while climbing Longs Peak, as the scrambling beyond it considerably slows most individuals. Be warned: From this point, you are only about halfway there time-wise. Stop to check the weather here. If storms are near, it’s best to head back and try another day. If things look clear, pass through the Keyhole and head to your left. 

You now enter a section called “The Ledges.” It’s a relatively easy section of scrambling with a dramatic drop-off to Glacier Gorge below. While the scrambling isn’t technically difficult, it may be a lot to handle for those who prefer avoiding heights. Follow the red and yellow bullseye marks painted onto rocks by the Park Service. These will lead you to the summit. 

Towards the end of the Ledges, you’ll enter a large boulder-filled gully called the Trough. This is where you’ll gain most of your elevation to the summit climbing Longs Peak. Follow the bullseye up the trough, passing back and forth from the left to the right side to take the path of least resistance. Wear a helmet during this section and beyond. Falling rocks are commonly knocked loose by those above you. If you knock a rock loose, shout rock to those below. If you hear rock – don’t look up, Look straight forward – your helmet will protect you. 

At the top of the trough lies the chockstone: a series of large rocks leaning up against one another. There are several ways to scramble up this rock. Take time, watch how others go up, and make it up and over this point into the Narrows section.

The Narrows takes you along the south face of the Longs Peak route as you traverse to the Homestretch. Here the scrambling is again not difficult, but a fall would be fatal. Take your time moving carefully, especially over one awkwardly placed rock early in the route.

Finally, the flat Homestretch takes you the last several hundred feet up to the summit. This is the crux of your trip climbing Longs Peak. The surface has many cracks which are perfect to follow up to the summit. Things are more difficult if the rock is wet or covered in ice. 

Finally, you’ll inch your way onto the strangely flat summit of Longs Peak! Enjoy a spectacular view of the entire Front Range, including Longmont, Boulder, and Denver below on the plains. Make sure you head back with time to make it back below treeline before noon. 

This isn’t an easy objective, so take your time gaining experience before you attempt to reach this summit. Best of luck climbing Longs Peak, and safe travels on the trail!

Longs Peak is located in the backcountry of Rocky Mountain National Park, a wild area with amazing wildlife. The area is busy – more than 40,000 try to climb the mountain each year. Please follow these Leave No Trace practices to help protect the vulnerable tundra and sub-alpine forest:

  • Plan ahead, review the route and pick a weekday or day in September to hike.
  • Stay on the trail, and keep dogs leashed on and off-trail to reduce trampling of alpine grass.
  • Leave your Bluetooth speaker at home and let nature’s sound reign.
  • Urinate off-trail, and pack out your waste – a cathole won’t work at high altitude.
  • Give wildlife a wide berth – 100 meters if possible. If they approach, back up to keep space.
  • Take nothing but pictures, and leave nothing but footprints.

Stay safe while climbing Longs Peak by following these essential mountain safety best practices for the Colorado 14ers.

  • Research your route: Choose an appropriate route based on your skill level, fitness, and the current conditions. Obtain trail maps and read up on trail descriptions, elevation gains, and potential hazards.
  • Check the weather: Weather conditions in the mountains can change rapidly, so check the forecast before heading out and be prepared for sudden changes.
  • Start early: Aim to begin your hike at or before sunrise to avoid being caught out in the afternoon thunderstorms, which are common in the mountains.

Longs Peak is the only Colorado fourteener located within a national park. This makes it a very busy peak, even though it is a difficult class 3 scramble. The difficulty of the climb often overwhelms people, unprepared for the thin air, severe weather, and exposed scrambling beyond the Keyhole rock formation.

The mountain is named after Stephen Long, an early U.S. explorer who first sighted the mountain in 1820 during an expedition to Colorado. The peak has been climbed for hundreds of years by Native Americans to collect eagle feathers from the summit. It was originally climbed by tourists via the “Cables,” a series of bolted in cables that ascend the sheer northeast face of the mountains. The National Park removed the cables because they were a lightning risk, and to preserve the wilderness experience, during the 1970s. The Keyhole route has been the standard route ever since.

Just below the Keyhole rock formation, the Agnes Vaille Shelter stands as an emergency refuge for hikers and climbers. It was built in 1935 by the family of Agnes, who died attempting the first winter climb of Longs Peak a decade beforehand. It’s a stark reminder of the hazards found on this route, the most deadly 14er in overall numbers.

To help preserve the natural wonder of Longs Peak, the National Park Service has implemented some rules and regulations you should be aware of before embarking on your journey.

First off, if you’re planning an overnight trip in the backcountry, you will need a Wilderness Camping Permit. These permits are designed to limit the impact on the environment and are issued on a quota system, so make sure you obtain one in advance. Day hiking does not require a permit, but remember to always stay on the designated trails to minimize damage to the park’s ecosystem.

Leashed pets are allowed in parking areas and established campgrounds, but not on trails. For the safety of your pet and the local wildlife, it’s best to leave your four-legged friends at home.

As part of the Leave No Trace principles, all trash must be carried out, including food waste. It’s not just a matter of respect for the environment; it’s also the law in the park. So pack a trash bag and plan to take everything out that you bring in.

While campfires are a quintessential part of camping for many, they are not allowed in the Rocky Mountain National Park backcountry, including the Longs Peak area, to prevent forest fires and preserve the natural state of the wilderness. Use camp stoves for cooking and dress warmly to stay comfortable without a fire.

Remember, hiking Longs Peak is not just an adventure; it’s a privilege. Adherence to these guidelines helps ensure that this stunning wilderness area remains intact for future generations of climbers to appreciate. Respect for the mountain and each other goes a long way in fostering a community of responsible and conscientious adventurers. So pack your gear, review these rules once more, and embark on the journey of a lifetime to the summit of Longs Peak. Stay safe and enjoy the climb!

A: Indeed, Longs Peak is considered one of the more challenging 14ers. The reasons include the length of the hiking route, the significant elevation gain, the exposed scrambling sections, and the high altitude, which can potentially cause altitude sickness in unacclimatized individuals. The Keyhole Route, the most popular route, involves navigating narrow ledges and climbing steep rock faces, demanding physical stamina and mental fortitude.

A: Yes, Longs Peak can be climbed in a single day. However, it is important to note that it will be a long and strenuous day due to the mountain’s height and the difficulty of the trail. The entire hike can take anywhere from 10-15 hours. Therefore, starting the hike very early in the morning is crucial to ensure you descend before afternoon thunderstorms typically roll in.

A: It is highly recommended to start hiking Longs Peak no later than 3 am. Starting this early is necessary if you aim to climb the peak and descend in a single day. It provides ample time to reach the summit and start your descent well before afternoon, when the risk of thunderstorms is high in the mountains. Remember, safety should always be your priority.
