Easy & Accessible Hikes

Accessible

  • The Meadow Trail is an gravel fire road that leads to a stream and is used as a trail by hikers, bikers and equestrians. It is not an official accessible trail, but it is the most accessible in the park. It may be accessible for about 3/4 mile. Occasionally gravel works loose and limits accessibility. The trailhead is approached from the white barn parking lot and the observatory. Restroom: An accessible portable toilet is near the visitor center and the observatory. Parking: The day use parking area currently has no lined spaces, but the surface is firm and stable. Dogs are not permitted on any trails or service roads within Sugarloaf Ridge State Park.
