Abyss Lake Trail #602

The Abyss Lake Trail is a popular hiking trail, ending at Abyss Lake. The lake is nestled in a high bowl-shaped depression formed by glaciers (called a glacial cirque) between Mount Bierstadt and Mount Blue Sky. The rocky slopes surrounding the lake are home to bighorn sheep and mountain goats.

The Abyss Trailhead provides access for the Abyss Trail (sometimes referred to as the Scott Gomer Trail) and the Burning Bear Trail within the Mount Evans Wilderness.

Specific Trail Information

Trail Number

602

General Information

No camping is allowed in the parking area.

Winter access: The road is plowed for the first 5 miles, meaning this trailhead is the farthest point north where the road is plowed.

Open year-round

There is a mandatory self-issuing permit system in the Mount Evans Wilderness and Lost Creek Wilderness areas to enable us to better manage visitation. The same type of system is also in place in other wildernesses. 

These permits have no quotas associated with them, nor are there any fees required to obtain them. They are available free at each trailhead. As you enter the wilderness area, fill out the provided permit and deposit the stub in the slot in the lower front of the register box. Keep the permit in your possession, and please follow the wilderness regulations found on the back.

The intent is to use the data obtained through the permit system to more accurately assess the amounts and types of existing wilderness use. This enables us to better preserve their natural condition for future generations, balanced against the pressures of growing populations and increased use.
