Red Lake Trailhead the Forest Service's write-up

The Forest Service designed Red Lake Trailhead for a family experience. The OHV trails travel across old logging roads and through scenic Aspen groves that are particularly nice in the fall. The trails also allow for riders to park their OHVs and access hiking routes, such as Buzzards Roost, that overlook the Spearfish Canyon. The trails are open from May 15 – December 15 to vehicles of 62-inch width or less. OHVs may travel on all routes marked or mapped as open. The gravel pit and piles near the parking area are not open to OHV use.

Access Red Lake Trailhead from Spearfish from Interstate 90, Exit 8, traveling south on McGuigan Road which merges to Tinton Road. Travel on Tinton Road (also National Forest Service Road, NFSR 134) for 13.4 miles. Turn left (east) at NFSR 134.2W. Signs indicate “Red Lake Trailhead” at the intersection of NFSR 134 with NFSR 134.2W. Travel east on NFRS 134.2W for approximately 0.1 mile to the trailhead.

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.
