Out and Back
Directions from Estes Park, take CO-7 E/S St Vrain Ave. for 9 miles. Turn right onto Longs Peak Rd. and travel about a mile to the Longs Peak Trailhead parking lot. Suggest arriving early since the parking lot fills up fast on summer weekends. A late arrival will mean parking up to a 1/2 mile down the road. There are no parking signs in specific locations. A valid backcountry permit is required for overnight parking.
The trailhead has restrooms and features a ranger station (with an emergency phone) and a small campground.
Hiking to the Boulder Field via the Longs Peak Trail is a challenging 12.3 mile out and back trail with a 3,360 feet elevation gain near Allenspark, Colorado. The trail offers great views of the east and north faces of Longs Peak, alpine tundra, the Boulder Field, the Agnes Vaille shelter hut and views into Glacier Gorge. This is a rewarding hike for those who do not wish to climb to the Longs Peak summit. There are several other popular hikes on the peak that don’t require climbing including Peacock Pool, Chasm Lake, the Keyhole, or the ridge between Mount Lady Washington and the east face of Longs Peak, which is called Chasm View. The 14,259-foot (4,346 m) Longs Peak is the northernmost “fourteener” in the Rocky Mountains and the highest point in Boulder County and Rocky Mountain National Park. The mountain was named in honor of explorer Stephen Harriman Long.
I started my hike just before 6 AM and on my downhill phase of the hike, an afternoon thunderstorm was blowing into the region. I suggest starting earlier at 4 AM and planning on being off the mountain between noon and 2 PM. Hikers at the higher elevations in the Rockies, including Longs Peak should be especially conscious about the dangers of lightning. According to the National Outdoor Leadership School, lightning density maps show lightning strikes occurring more often at higher elevations in the Rocky Mountains where the air and climate is drier. On average, eleven people die from lightning each year in Colorado.
Starting hiking in the early morning darkness, the East Longs Peak Trail starts the climb though the Goblins Forest. This forest has uniform lodgepole pine trees.
Hike 0.5 miles to a signed trail junction and stay left on the main trail. Continue up through the forest and pass Goblins Forest. Switchback up a hill before crossing Alpine Brook on a log bridge. Since I started at 6 AM, the sun is starting to rise over the hills by the time I get up to the noisy Alpine Brook and Larkspur Creek. Towards the top of the Goblins Forest, there are subalpine fir, limber pine, and Engelmann spruce trees.
As the trail reaches the tree line, the vegetation turns to crooked, bent and twisted krummholz trees. These trees are a type of stunted, deformed vegetation encountered in the subalpine tree line landscapes. Above the subalpine krummholz landscape lies numerous conifer species in an open treeless tundra.
Leave the heavy forest shortly after the stream crossing and continue up to tree line near 11,000′ (approximately 2.5 miles from the trailhead). Longs Peak is now in view as well as the route past Mt. Lady Washington and to Granite Pass.
The traverse is a moderately long 4.2 miles with an elevation gain of 2,680 feet to Granite Pass (Elevation 12,080 feet). From Granite Pass, the view to the north begins to reveal Rocky Mountain National Park. Continue along the switchbacks up to the North Boulder Field. Longs Peak will now be in view as you ascend the mountain.
The North Longs Peak Trail heads off to the right. Stay left on the East Longs Peak Trail and switchback up and easy slope to reach the north end of the Boulder Field, near 12,400′. The north and east faces of Longs come into view, as well as Storm Peak (13,326′) ahead. Follow the trail south into the Boulder Field and past some established tent sites in the middle of the field. There is a restroom in this area.
I would rate this hike as difficult with an estimated hiking time of 6 to 8 hours. See my nearby Strava.com file from my hike on August 23, 2017, which took me just under 7 hours (moving time) with my elapsed time taking about 8 hours. I did this hike with a sore meniscus on my left knee and an injured left quad muscle that kept me out of both the 2017 London and New York City marathons. I didn’t start running again until February 2018. Later that fall I finished the New York City Marathon. I was determined to hike up to the Boulder Field nonetheless, despite my knee challenged status. Most of the other hikers on the mountain that day quickly passed me. Trekking poles are a must on the downhill phase even if you don’t have a sore meniscus.
Camping is available at the Boulder Field and also on the lower portions of the mountain, such as Goblin’s Forest next to the stream at the bottom. It is also possible to camp to the south of the mountain at Sand Beach Lake. Camping is first-come, first-served, limited to 3 consecutive days, and is tents only.
