Lost Lake is not far from the town of Nederland, just outside the Indian Peak Wilderness Area. The Lost Lake Trail trailhead is located at about 9,000 feet and from there you will gain 903 feet in elevation, so expect to climb. The trail heads west through the beautiful aspen forest, making it pleasant and cool in spite of the steady climb. Once you come out of the trees, you will catch a beautiful view of the surrounding mountains and the valley below. As you keep climbing, you will hear Middle Boulder Creek as it rushes to the left of the trail. The trail heads back into the forest, and will stay shady all the way to the lake. There are eight campsites around the lake, which is full of fish.
