The Abyss Trailhead provides access for the Abyss Lake Trail (sometimes referred to as the Scott Gomer trail) and the Burning Bear Trail north of the community of Grant. The Abyss Lake Trail is a popular hiking trail in the Mount Evans Wilderness Area, which terminates at Abyss Lake. The lake is nestled in a high glacial cirque between Mt. Bierstadt and Mt. Evans. The rocky slopes surrounding the lake are home to bighorn sheep and mountain goats. The elevation gain, together with the round trip distance of 18 miles, makes this a strenuous day hike. The trail is not marked with signs but can be used for cross country skiing or snowshoeing. The first 2 miles are considered easy, while the next couple of miles are intermediate.
The east trailhead for the Burning Bear Trail is approximately .2 miles west of the parking area for the Abyss Trailhead (9,620 ft. elevation). The trail proceeds west into Hall Valley. From the trailhead gate, the trail leads northwest in an open meadow for about 200 yards, and then crosses a large bridge over Geneva Creek. Mountain biking is allowed on the Burning Bear Trail.
From Denver, drive southwest on US 285 approximately 40 miles to Grant. Turn right (north) onto Park County 62 (towards Guanella Pass). The Abyss Trailhead is approximately 5.5 miles north on the Guanella Pass Road. During the winter, the road is plowed for the first 5 miles, meaning this trailhead is the farthest point north where the road is plowed. There is a large parking area for this trailhead.
