Diamond Rock runs from the paved FR 249 in the north to very near the Buffalo Crossing bridge on the Black River's East Fork. In the north, the trail passes through a pine forest with numerous large dispersed campsites. The trail parallels the East Fork on the southern end, dotted with pullouts for river access and numerous small waterside campgrounds. The campgrounds all offer picnic tables, fire grates, vault toilets, and potable water in season. The area is very popular with anglers in search of wily trout. The trail is generally easy, with mountain grades, sharp curves, and one-lane bridges.
