Route Description

Longs Peak Keyhole Route

I recommend reading through this description and saving a screenshot on your phone to review when needed on the trail.

The Trail

The adventure to Longs Peak begins at the Longs Peak Trailhead, located at an elevation of 9,405 feet. The trail starts in a dense forest of pine and spruce, providing a moderate and well-maintained path. After approximately 2.5 miles, you’ll reach the junction with the Chasm Lake Trail. Stay on the Longs Peak Trail, which gradually ascends through Goblins Forest. As you climb higher, the forest thins out, offering breathtaking views of the surrounding peaks and valleys.

The Boulderfield

After about 5.5 miles, you’ll arrive at the Boulderfield, situated at an elevation of approximately 12,760 feet. This area is a sprawling expanse of large, jagged boulders. The trail becomes less defined here, requiring careful route-finding and balance. Look for cairns (small piles of rocks) that mark the way. Camping is permitted in designated spots within the Boulderfield, making it a popular place to rest before attempting the summit.

The Keyhole

At the western edge of the Boulderfield lies the Keyhole, a distinctive rock formation that marks the transition from hiking to scrambling. The Keyhole is at an elevation of 13,150 feet. From here, the route becomes more technical. As you pass through the Keyhole, you’ll see the dramatic shift in terrain. The view opens up to the north face of Longs Peak, with steep cliffs and rugged landscapes.

The Ledges

Beyond the Keyhole, the route traverses the Ledges. This section involves navigating narrow ledges with significant exposure. Red and yellow bull’s-eyes painted on the rocks guide you along the path. Move cautiously and maintain three points of contact at all times. The Ledges can be icy or wet, so ensure you have proper footwear and traction devices if necessary.

The Trough

The Ledges lead to the base of the Trough, a steep and narrow gully that rises about 600 feet to the ridgeline. This section is physically demanding, requiring a mix of scrambling and climbing over loose rocks and scree. Helmets are recommended to protect against potential rockfall. Take your time and follow the bull’s-eyes carefully, ensuring each hand and foothold is secure.

The Narrows

At the top of the Trough, you’ll reach a notch that leads to the Narrows. This section is aptly named, as it consists of a narrow path along a steep cliff face. The Narrows offer breathtaking views but demand utmost caution. The route is well-marked, but the exposure can be intimidating. Focus on your footing and handholds, moving steadily and confidently across this section.

The Homestretch

After navigating the Narrows, you’ll arrive at the Homestretch, the final push to the summit. This steep, smooth slab of rock rises about 300 feet. The angle can reach up to 45 degrees in some places, requiring you to use both hands and feet to ascend. The rock is often polished and can be slippery, especially when wet or icy. Follow the cracks and natural features for the best hand and footholds.

The Summit

Finally, after conquering the Homestretch, you’ll reach the summit of Longs Peak at 14,259 feet. The summit is a broad, flat area with stunning panoramic views of the Rocky Mountains. Take time to savor your achievement and enjoy the majestic scenery. Be mindful of the time and weather, as afternoon storms are common. When ready, carefully retrace your steps back down, maintaining vigilance and caution on the descent.

Leave No Trace

Longs Peak is a popular 14er, with more than 50,000 climbers visiting each year. It is important to use Leave No Trace practices to avoid damaging the fragile alpine ecosystem. Here are some tips and best practices to use during your climb.

Plan Ahead and Prepare

  • Understand the regulations and special concerns for the area you’ll visit.
  • Check the weather forecast, and be aware of the terrain challenges you might face on Longs Peak.
  • Preparation reduces the likelihood of resource damage and contributes to your safety.

Travel and Camp on Durable Surfaces

  • Stay on established trails and avoid cutting switchbacks, which can lead to erosion.
  • In the alpine tundra, plants take years to grow and mere seconds to be destroyed by trampling.
  • If camping is part of your trip, use designated campsites at lower elevations to minimize impact.

Dispose of Waste Properly

  • Pack out all your trash, leftover food, and litter.
  • It’s essential to carry a bag for collecting waste.
  • For human waste, dig a cat hole 6-8 inches deep at least 200 feet from water, trails, and camp. Cover and disguise it when finished.
  • Pack out all toilet paper and hygiene products.

Leave What You Find

  • Preserve the past; examine, but do not touch, cultural or historic structures and artifacts.
  • Leave rocks, plants, and other natural objects as you find them.
  • Avoid introducing or transporting non-native species by cleaning gear and boots before and after your hike.

Minimize Campfire Impacts

  • Campfires can cause lasting impacts in the alpine environment.
  • Use a lightweight stove for cooking and a lantern for light.
  • If fires are permitted, use established fire rings, keep fires small, and burn all wood to ash.
  • Put out fires completely and scatter cool ashes.

Respect Wildlife

  • Observe wildlife from a distance and never feed them. Feeding wildlife damages their health, alters natural behaviors, and exposes them to predators and other dangers.
  • Control pets on a leash at all times, or leave them at home.

Be Courteous to Others Outdoors

  • Respect other trail users and protect the quality of their experience.
  • Use headphones, not bluetooth speakers, and keep your noise down.
  • Give uphill hikers the right of way.
  • Step to the downhill side of the trail when encountering pack stock.
  • If stopping, move off the trail to allow others to pass.

Incorporating these LNT principles into your Longs Peak adventure is a commitment to conserving the mountain for future generations to experience and enjoy. By acting as stewards of the land, we can all contribute to the sustainability of the natural beauty that draws us to these heights.

Safety Tips

Longs Peak is an extremely dangerous and deadly mountain. More people have died on this peak than on any other mountain in Colorado. It is important to take the route seriously and give it the respect it deserves. Follow these safety best practices to ensure you make it back to the trailhead in one piece.

  • Acclimate to Altitude: Spend a day or two at a lower elevation near Longs Peak to get your body used to the altitude. Altitude sickness can be a serious concern and can strike regardless of fitness level.

  • Check the Weather: Mountain weather is notoriously unpredictable. Before you set out, check the local weather forecast and be prepared for sudden changes. Start early to avoid afternoon thunderstorms common in the Rockies.

  • Stay Hydrated: At high altitudes, your body dehydrates faster. Carry plenty of water — a minimum of 2 to 3 liters per person — and drink regularly throughout your hike.

  • Research Your Route: Take time to review trip reports, route descriptions, maps, and photos to help you navigate in the field and know if you are on the right track.

  • Dress Appropriately: Layer your clothing to adapt to the variable conditions. Include a moisture-wicking base layer, an insulating layer, and a waterproof and windproof outer layer. Don’t forget a hat and gloves, even in summer. Top it off with a climbing helmet to wear in the class 3 sections.

  • Stay on the Trail: For your safety and the environment’s protection, stick to designated trails. Shortcuts can lead to erosion and habitat destruction and can also put you at risk of getting lost or injured.

  • Know Your Limits: Longs Peak’s terrain can be challenging, with loose rocks and steep sections. If you’re not an experienced hiker or if you’re feeling unsure, consider hiring a guide or joining a group.

  • Emergency Plan: Have a plan in case of an emergency. Inform someone of your route and expected return time. Carry a whistle, a mirror, and a small first aid kit. A satellite messenger or personal locator beacon (PLB) is advised for remote areas where cell service is not reliable.

  • Bring a Buddy: Never hike alone. Use the buddy system to ensure safety. If one person gets injured or sick, the other can go for help.

  • Share Your Itinerary: Tell someone dependable back home that you are climbing Longs Peak and share as much of your plans and itinerary as possible. Tell them you when you will check-in with them, and who to call if you fail to do so.

Respecting these safety guidelines will help ensure that your climb up Longs Peak is memorable for all the right reasons. Stay alert, stay safe, and enjoy the grandeur of the Rockies.

About Longs Peak

Longs Peak, standing at 14,259 feet, is the highest mountain in Rocky Mountain National Park and one of Colorado’s most iconic fourteeners. Named after Major Stephen H. Long, an early explorer of the Rocky Mountains, this peak has captivated climbers, hikers, and nature enthusiasts for centuries.

Historical Significance

Longs Peak holds a rich historical significance, deeply rooted in the exploration and settlement of the American West. Major Stephen H. Long, an engineer and explorer, first documented the peak during an 1820 expedition. However, it wasn’t until 1868 that the summit was first successfully reached by John Wesley Powell and his team.

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.

A: No, the National Park Service does not permit sleeping in cars at the Longs Peak Trailhead. This policy helps protect the park’s natural resources and ensures visitor safety. However, there are nearby campgrounds and lodging options available for overnight stays. Please ensure to plan your trip in advance, taking into consideration these accommodation rules.

A: Certain parts of Longs Peak, specifically the North Face or ‘Cables Route’, are considered technical climbs. These require specific rock climbing skills and equipment. However, the standard route up Longs Peak, known as the Keyhole Route, is considered a Class 3 scramble. This means it doesn’t require the use of ropes or other technical climbing gear, but it does involve using your hands for balance and support during certain sections of the climb.
