Lone Pine Lake - 10.8 Miles Round-Trip

Lone Pine Lake is located 5.4 miles from East Inlet Trailhead on the west side of Rocky Mountain National Park. This diverse trail features abundant wildlife, large meadows and excellent fishing. The East Inlet Trail continues on to Lake Verna, Spirit Lake, Fourth Lake, Fifth Lake and Boulder-Grand Pass, which crosses the Continental Divide:

The trail passes spurs for Adams Falls (.27 miles) and levels along the north edge of East Meadow, an open expanse cut by slow moving oxbows on the East Inlet.

This is a popular destination for anglers, and great place to see moose. Enjoy good views and a diverse collection of flowers on this fast-moving stretch.

The trail enters a thinned-out lodgepole forest to Lower East Inlet backcountry campsite (2.35 miles : 8,685’), where grades steepen on rugged terrain up the valley’s north wall. It crests at 3.45 miles (9,220’) and drops to the creek, where healthier fir trees appear and soften the aesthetic loss from pervasive beetle kill.

The trail eases by a slow section of water before rising away to the Cats Lair backcountry campsite (3.8 miles : 9,210’). It edges back to the creek and undulates to a bridge over to the south side of East Inlet (4.35 miles : 9,405’), just past which are a series of powerful cascades. This is a good turnaround point if not aiming for the lakes.

The trail steepens away from the creek on a rocky-rooted path to the Gray Jay Group campsite (5.05 miles : 9,805’), then crosses a debris field created by a recent avalanche. The NPS has done a great job making it passable, but expect fallen trees and vague spots on this short segment.

Travel moderates on the final run to Lone Pine Lake (5.4 miles : 9,885’), with multiple access points to its open perimeter. Look for moose in the vicinity, which are drawn to the marshy basin’s willow and aquatic plants.

Continue a short distance past Lone Pine to see its kinetic inlet, and up switchbacks beside the falls to open rock slabs with terrific views over the lake. Social trails on Lone Pine's west shore have partial views up-valley of Andrews Peak (12,565'), Mt Alice (13,310'), Boulder Grand Pass (12,061'), Isolation Peak (13,118') and Mt Craig (12,007').

Worth Noting

  • Moose are frequently seen on the East Inlet Trail. Look for moose browsing in marshy meadows in the early morning, and in dark timber later in the day as temperatures rise. Keep a safe, respectful distance from wildlife.
  • Mosquitoes can be a nuisance on the East Inlet corridor. Long sleeves and repellant are highly recommended.
  • Lake Verna is 1.5 miles from Lone Pine Lake, and Spirit Lake is 1.0 miles further on an unimproved trail from Verna. The unimproved trail can be difficult to follow, especially with lingering snow.
  • The East Inlet Trail has 8 backcountry campsites between the trailhead and Lake Verna that fill up quickly throughout the summer. Advance reservations are necessary.
  • Contact the ranger station for fishing rules and regulations. A Colorado fishing license is required. Rules are strictly enforced.

Fishing Information

  • Fishing is permitted along the East Inlet and at each lake with a valid Colorado fishing license. Specific rules may apply to each lake and various sections of the East Inlet. Consult the RMNP backcountry office for the latest rules and regulations.

Rules and Regulations

  • There's a $20 fee to enter Rocky Mountain National Park.
  • Camping is not permitted at Lone Pine Lake.

"Hiking this trail is one of the best memories of my life. I hiked this trail with a dozen other people. We hiked in and set up camp at Gray Jay campground located just a short walk from Lone Pine Lake. The first stretch of the hike was a little buggy in the marshy areas, but not annoyingly so. Once we set up camp, it was starting to get dark so we just made dinner and slept early to prep for an early hike the next day. The trail was well maintained along the north side of Verna but was much narrower and overgrown past that heading toward 4th and 5th. The first day we spent just lounging around Verna. The second day we woke early again for a longer hike toward the continental divide. Following the stream East just beyond 4th, you get to a point where you exit the trees and in front of us was one of the most spectacular views I'd ever seen. It felt like what I imagine heaven looking like. Moose crossing the stream through the tall grass, with a background of an avalanche chute straight ahead and Isolation peak to the South. Patches of snow linger, arching over the bubbling stream. Wildflowers of many colors are in abundance. Clear blue sky and lots of sunshine. This is a hike that I will take again after my wedding with my new bride. It is the most beautiful place I've ever been. A word of advice though. As tempting as it may be, do not scramble up the avalanche chute in an attempt to reach the divide. A couple of my more adventurous friends and I tried and found ourselves in a tight spot with NO equipment. It was scary and pointless, as walking up through the woods to the north would make for a much more gradual and do-able hike up to the divide. We never did take the hike up to 5th but I will the next time I go, just to get closer to Isolation Peak. I love this trail, it was fairly easy even for the newbies we had in our group. Can't recommend it highly enough."
