Lost Lake is located in the Eagles Nest Wilderness Area and Dillon Ranger District of the White River National Forest. This green-tinted lake straddles treeline beneath Uneva Pass, 4.95 miles from Copper Mountain Ski Resort along the Gore Range Trail.
Visitors will enjoy terrific views across the Gore and Ten Mile ranges, idyllic alpine meadows, and excellent backcountry camping options en route to Lost Lake:
From Copper Mountain Ski Resort's Alpine Parking Lot, walk .35 miles east over the I-70 pedestrian bridge to a sign marking the Gore Range Trail on your left (9,725').
The trail rises gently through a sage-aspen hillside over I-70, gradually bending north into a thick forest and across the Eagles Nest Wilderness Boundary (1.2 miles : 10,195').
The grade steepens considerably through quick intervals of spruce and large clearings to the edge of a broad meadow (1.85 miles : 10,778'), a welcome reprieve through archetypal elk and moose habitat.
It skirts the meadow and winds moderately to the Wheeler Lakes Trail split (2.55 miles : 11,077'). The Gore Range Trail continues north through a string of lofty meadows and trio of scenic ponds (3.6 miles : 11,365').
It passes leisurely by the ponds into a thick forest and rises sharply on a shifting climb to a crest over the upper drainage of Officers Gulch.
The trail drops into and crosses the marshy drainage area on an ill-defined path, negotiating tangled willows and rushing streams to a clear path on the far side (4.25 miles : 11,423'). Take a moment to locate the trail before making the cross.
Once over it rises through the vestiges of treeline to a talus field (4.65 miles : 11,478') and stream crossing, which is Lost Lake's outlet (4.8 miles : 11,535').
A short push leads to the high east bank of Lost Lake (4.95 miles : 11,621').
Lost Lake is partially concealed by the bank and stands of gnarled spruce, however clearing treeline should prompt you to look back and find it. Consider hiking a bit past Lost Lake and approaching it through its open north shore, a less-obstructed option. Those with time may continue another half mile and 300' up to Uneva Pass, or take a .5 mile roundtrip excursion to Wheeler Lakes on the return.

- Lingering snow may obscure portions of the Gore Range Trail. Follow cairns, be patient with route finding and help minimize erosion by staying on designated trails.
- Much of this trail passes through exposed areas near treeline. Get an early start to enjoy the open high country and return safely below treeline before summer storms develop.
- Anticipate changing weather conditions throughout the day. Carry versatile layers, sun, wind and rain protection.
- This is a popular destination for both dayhikers and backpackers. Arrive early to avoid crowds and secure preferred campsites near the lake.

The Gore Range Trail can be accessed from several parking areas along I-70 to reach Lost Lake. Each requires that you trace I-70 for a short time before turning north on the main trail. The most convenient access point for most visitors begins at Copper Mountain Ski Resort's Alpine Parking Lot.
Parking is free in the summer, but overnight permits are required.
From Denver, take the 195 - Copper Mountain Exit off I-70 and proceed to the Copper Mountain Ski Resort. Turn right on Copper Road into the resort, then immediately left into the Alpine Lot. Walk .35 miles east back over the I-70 pedestrian bridge. A sign marking the trail is located just over the bridge on your left (north). Mileage described above includes this .35 mile walk from the Alpine Lot.
You may alternatively park on the small shoulder to your right just off the 195 exit ramp, or at the Officers Gulch Exit off I-70. The latter requires a longer walk along I-70 to reach the main trail.
