36 CFR Part 1191 ABA Accessibility Guidelines, Outdoor Developed Areas - Preamble

F216.13 Trailhead Signs

Where new trail information signs are provided at trailheads on newly constructed or altered trails designed for use by hikers or pedestrians, this section requires the signs to comply with the technical requirements in 1017.11, regardless of whether the trails comply with the technical requirements in 1017. The technical requirements in 1017.11 require the signs to include information on the length of the trail or trail segment; surface type; typical and minimum tread width; typical and minimum running slope; and typical and minimum cross slope. This information enables individuals with disabilities to decide whether to hike the trail based on the characteristics of the trail. Entities should also provide information about the accessibility of trails on websites.

If trail information signs designate the name of the trail, only the name of the trail is required to comply with the technical requirements in 703.5. See F216.2. Tactile characters are not required on exterior signs. Trail information signs are not required to display the International Symbol of Accessibility.
