Need To Know Information
- This hike is located within Rocky Mountain National Park, however you do not need a pass to get in as this doesn’t take you through an entrance gate for the Longs Peak Trailhead. A pass is needed for the Glacier Gorge Trailhead.
- Dogs are not allowed in RMNP and therefore are not allowed to Chasm Lake.
- Longs Peak is a difficult 14er with class 3 hiking and serious exposure. Past scrambling and class 3 experience is highly recommended.
There are two main “hiking” trails to Longs peak that feature Class 1 and 2 hiking up until the Keyhole (a unique rock formation). The hike is considered class 3 after the keyhole. Below, each is shown. The East Longs Peak Trail is by far the more popular route. This hike is attempted an estimated 20,000 times per year by hikers with a less than 50% completion rate. Though this hike is difficult, and especially dangerous during poor weather, it is stunning, and doable for most intermediate to experienced hikers. Caution and good judgement is highly recommended. Most hikers are told to start by 6 a.m. at the latest.
East Longs Peak Trail: 15 miles Round Trip | 5,370 Feet Elevation Gain
This trail begins at 9,380 feet on Longs Peak road (directions below). Hikers will begin hiking through some pretty forest gaining elevation at a steady pace. Hikers will break through tree line 2.5 miles into the hike. Here hikers will get outstanding views eastward to the flatlands, and towards Longs Peak.
Once breaking tree line, the views simply remain outstanding throughout this hike. 3.2 miles in, hikers reach the junction for Chasm lake (a must see). There is a privy at this intersection. Hikers will bear right to continue upwards and around Mount Lady Washington. Once ascending above the a ridge, the views into Rocky Mountain National Park are incredible.
Just about 5 miles in, hikers will reach the boulder field. Some consider Boulder Field to be the most difficult part of the hike to Longs Peak (people that hate boulder hopping). There are big boulders and the hikers have to scramble over them before they reach the keyhole 6 miles into the hike. The boulder field has campsites (permit needed) and bathrooms for hikers. The views from the boulders are of course outstanding. Hikers will often stop at the Keyhole due to the trail becoming class 3 and significantly more dangerous beyond it.
Beyond the Keyhole, hikers will experience large cliffs, slippery rock, loose rock, steep inclines, the chance for falling rock, but some of the most gorgeous views. Extreme caution must be taken here as wind, ice, falling rock, or rain significantly amplify the dangers of this hike. Beyond the keyhole are four well known sections to the summit, The Ledges, The trough, The Narrows, and The Homestretch.
Pictures of this trail can be found below.
It is advisable to start the hiking first thing in the morning before the dawn. This increases the chances to return before the afternoon as this time is known for frequent thunderstorms and lightning.
North Longs Peak Trail 9.5 miles each way | 5,200 Feet Elevation Gain
This hike begins at the Glacier Gorge parking area in Rocky Mountain National Park off of Bear Lake road (directions below). This is a gorgeous option to head up, and far less traveled after the first couple of miles. Once hikers reach Granite Pass, they meet up with the East Longs Peak trail and are only 1.8 miles from the keyhole.
If you are looking for a two-day hike, you can camp in the Boulder Fields. Permits to camp can be very hard to come by, but can be found here.
Many choose to stay at Longs Peak Campground to get started early in the morning. Information can be found here.
1.2 miles into the hike lies the Goblins Forest Backcountry Campground, which contains 6 tent sites. Information can be found here.
