Trailhead Munger Mountain North Trailhead Drive there

Munger Mountain North Trailhead the Forest Service's write-up

This trailhead is located off of the Fall Creek Road out of Wilson, Wyoming just before Red Top Meadows. It has a small gravel parking area directly off the road in an open grassy area surrounded by beautiful aspen stands. This is the main non-motorized access to the Munger Mountain Trail System, but is open to motorcycles from 07/01 to 09/09. The main access trail begins right across the road from the parking area and accesses several other multi-use trails including the Poison Cr Trail #4207, the Wally World Trail #4207A, the Tuscany Trail #4206, and the Paamus Naokwaide Trail (formerly Squaw Cr Trail #4205B). This area has the largest contiguous aspen stands on the district and is absolutely stunning during the fall months. No facilities are located on site. Single kiosk with a map. No cellular service available. Trailhead is large enough for trailer turnaround.

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.
