Glen Alpine Trailhead the Forest Service's write-up

Glen Alpine Trailhead is located on the south end of the Lake Tahoe Basin near South Lake Tahoe, and serves as an entry point for Desolation Wilderness . From South Lake Tahoe, take Highway 89 north approximately three miles to Fallen Leaf Road. Watch for bicyclists, pedestrians and other cars on this narrow, one-lane road. Keep going around the south end of Fallen Leaf Lake, then turn left before the bridge and continue toward Lily Lake to the trailhead.

Many different hikes can be taken from this starting point. For a short walk, take the southern spur three miles to Grass Lake or stretch the hike to six miles all the way to Lake Aloha. Another moderate spur takes you to Half Moon or Alta Morris lakes. A third spur takes you to Gilmore Lake and then on to Dicks Pass. At Gilmore Lake another trail heads up the backside of Mt. Tallac, which offers a moderate approach to the summit.

A wilderness permit is required to enter Desolation Wilderness. Day hikers may pick up permits at the trailhead kiosk. Overnight hikers should obtain an overnight permit before arriving. Hard-sided bear canisters are required for all overnight visits. Campfires (wood, charcoal or any other solid fuels) are not permitted.

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.
