Greyrock Trailhead (#946)/Greyrock Meadows (#947) the Forest Service's write-up

The trail gently rises for ¾ mile then divides. The left branch, Meadows Trail (#947), is the slightly less strenuous but longer, and rejoins the main trail about 2.6 miles later. The right main branch turns uphill for 1.7 miles where it meets the upper end of the Meadows Trail. From the upper junction an additional ¾ mile climb leads to the summit. Trailhead signs warn of Giardia in the water and poison ivy growing along the trails of Greyrock. Greyrock trailhead accommodates approximately 39 vehicles.

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.
