Klamath National Forest · California
Trailhead Boulder Creek Trailhead Drive there
The Boulder Creek Trailhead is on Forest Road 44N53Y, off of Forest Road 44N45 just past Indian Scotty Campground.
The trailhead provides access to Trail #5534 into the Marble Mountain Wilderness. The trail connects with Trail #5535 toward Muse Meadow and Deep Lake, or to Trail #5529 circling 8,299' Boulder Peak and passing the Upper and Lower Wright Lakes.
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.
