Longs Peak is the queen of the front range, rising high above the northern Colorado rocky mountains. She isn’t a mountain to be trifled with; More people have died climbing Longs Peak than any other mountain in the state. Most who perish or get injured do so because they’re unprepared and don’t realize the significance of this route. It involves long distances, climbing on steep rock, and requires and early 2am start to be back below tree line before afternoon storms hit. Be prepared before you attempt climbing Longs Peak.

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!
No guide is complete without a topographical map of the route. If you plan on climbing Longs Peak, you will need it to navigate and stay on route.

Trailhead Access and Parking: Navigating the Rules and Tips
Longs Peak Trailhead parking lot is available on a first-come, first-serve basis and has a reputation for filling up quite early during the peak season (July through September). Arriving before sunrise is highly recommended for securing a spot, plus, it offers you an early start on the trail, which can be crucial for your safety given the often unpredictable afternoon weather patterns on the mountain.
Please note, overnight parking is allowed, but you must obtain a wilderness camping permit if you plan to camp along the trail. This restriction is enforced to help protect the natural beauty and integrity of the park, ensuring it remains a pristine environment for all hikers to enjoy.
It’s important to know that no parking is allowed along the access road outside of the designated parking area. Be sure to follow all posted signs and regulations to avoid fines and vehicle towing.
Year-Round Accessibility: Embracing the Seasons
Longs Peak Trailhead is accessible year-round, but the climbing conditions vary significantly with the seasons. The keyhole route is usually snow-free and most popular from July to early September. Outside of these months, the trail can be covered in snow and ice, requiring mountaineering skills and equipment. It’s always crucial to check weather conditions and consider your experience and preparation before setting out.
Longs Peak is a serious 14er with plenty of hiking and scrambling required to reach the summit. A good pair of hiking boots are essential if you want your best chance for a successful ascent. Here are my hiking boot recommendations.
You should always bring the ten essentials with you on your trip (see the infographic below). This is especially true on a dangerous peak like Longs Peak. To carry them all, bring a backpack with 20-30 liters capacity. These are several good backpack options that won’t break the bank.
While trekking poles are not a necessity on this mountain, I use them myself as they offer many benefits and make hiking easier. If you want a pair, I share my personal favorites here.

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.

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!
