Hike to the Top of Longs Peak in Rocky Mountain National Park

It is impossible to stare at the eastern skyline of Rocky Mountain National Park and not be compelled to at least wonder what it would be like to climb Longs Peak. Dominating the skyline, and topping out at 14,259 feet, Longs is the ultimate adventure for enthusiastic hikers.

Don't be fooled though, it's not a walk in the park. In fact, the 16-mile round trip hike will push hikers lungs and stamina to the test. The reward? Unobstructed 360 degree views spanning the eastern plains and continental divide.

Two rules come into play when hiking Longs: Start early and drink more water than you think necessary. When planning an assent, try to organize it so you can hike during the tail end of your trip. The few days of being in the park will help your body acclimate to the high altitude.

Longs Peak Trailhead

The journey starts from the Longs Peak Trailhead located along CO-7 10.2 miles from Estes Park. Most hikers typically begin before dawn, since afternoon thunderstorms usually roll in around 12 or 1 pm and can be life threatening above tree line.

The first two miles gain steady elevation while passing through Goblin's Forest. After crossing several small streams, the trail emerges from the trees and crosses into open tundra. Time this right and the sun will just be peaking out across the eastern horizon. Looking ahead you will now be able to see Longs looming in morning darkness.

Chasm Lake Trail Junction

The trail continues to gain elevation while feeding through open tundra filled with jagged rocks and boulders lit by the early morning sunrise. At Chasm Lake Trail Junction, grab a quick snack and soak in views of Longs 18-acre granite face known as the Diamond. The face can be climbed by experienced climbers and typically is considered a top tier destination.

After the junction, follow the trail gaining steady amounts of elevation while wrapping around a small ridgeline. The hike then enters the boulder field, a large relatively flat field of boulders where a few backcountry campsites reside. The infamous keyhole, which leads to the only non-technical route up Longs Peak, is now visible directly ahead at the top of the boulder field.

The Keyhole

Before passing through the keyhole, check for storm clouds building on the horizon. Past this point the trail is fully exposed and can be dangerous if a thunderstorm rolls in. Always remember to error on the side of caution and heed a hikers well-known saying: the mountain is not going anywhere; it will be here another day.

Pass through the keyhole and begin a final mile-long ascent to the summit. To navigate, follow spray painted targets to the base of a long trough. As you ascend the trough, don't forget to turn around for some of the best views in the Park of Glacier Gorge to the North.

The large flat summit of Longs has unobstructed 360-degree views of the eastern plains, Indian Peaks Wilderness to the south, and the Rocky Mountain National Park to the west. To return, retrace your route back to Longs Peak Trailhead.

Note: If you start to feel nauseous, it's probably a resort of high altitude. Start heading back down to lower elevations where the symptoms should reside. If they persist, it's best to seek a doctor.
