Trailhead Wall Lake #1818 Drive there

Wall Lake #1818 the Forest Service's write-up

The Wall Lake Trail is one of the quickest and steepest routes up onto the Flat Tops. Leaving the trailhead just above the Trappers Lake campgrounds, the trail immediately enters lodgepole pine and spruce that were burned in the 2002 Big Fish Fire. The burned area continues until roughly 2 miles above Anderson Lake. Please use extreme caution among standing dead trees. Atop the plateau, the trail meets Oyster Lake Trail (#1825) , providing access to the west. Roughly a mile past the Oyster Lake Trail junction the trail reaches Wall Lake. Wall Lake sits nestled below the 12,002' Trappers Peak. The trail stays on the west side of the lake, climbing the "wall" and crossing a saddle into the South Fork drainage. The trail continues across the tundra for 2 miles and ends at Trappers Lake Trail (#1816) .

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.
