Rim Lake TH #1856 the Forest Service's write-up
Rim Lake Trail follows the Sweetwater Trail for 3.1 miles before climbing another 5.1 miles to Rim Lake and Trapper's Lake Trail. The Sweetwater Trail is quite gentle, then the Rim Lake Trail gets steeper as it gets closer to the Lake, which rests up out of the valley on the Flat Tops plateau.

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.
