Keystone Gulch Road TH #175 the Forest Service's write-up

season Typically July 1 to

Fall 2024: Anticipate second gate at ski area boundary open through 1st season; closing when Keystone begins making snow.

The Keystone Gulch Road follows the boundary of the Keystone Ski Area at the beginning and eventually enters the ski area in the North Peak area. The lower gate for this road remains closed to motorized access later on in the season, typically until July 1, to protect elk calving. The trail gradually climbs through a heavily forested area for about 5 miles. Approximately 2.8 miles from the trailhead you will come to the base area of the Ruby and Santiago Lifts. Approximately 0.7 miles from the summit you will see a trail to the right which will take you to the old Erickson Mine. The mine is approximately 1.0 miles from the main trail. A second gate has been installed on North Peak, by Labonte's Restaurant, which closes that area to motorized access . This is to protect the area from rutting and other resource damage.

About this trail's facts

The lines are the US Forest Service's National Forest System trails layer (public domain), read 2026-10-16 and simplified for the map; the length is the line's, end to end, and the class, surface, grade and tread width are the forest's own entries where it publishes them - a forest that publishes the centreline alone has none. The trailheads and the points along the way are the Service's recreation points, and the write-ups its own recarea text, unedited. Heights come from USGS 3DEP through Terrain Tiles on AWS (Mapzen/Tilezen), read along each line and rounded; a short trail on steep ground can be off by a few tens of feet. Closures change: check the forest's own site before you go.
