Klamath National Forest · California
Trailhead Kelsey Trailhead Drive there
Just west of the Scott River on Kelsey Creek you pick up the Kelsey National Recreation Trail. Originally built in the 1850's, the trail served as a supply route from the coast to Scott Valley and the military post at Fort Jones. Today the trail serves as a popular day hike to Paradise Lake and connects backpackers to the PCT.
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.
