Sign-in at trailhead. Described in detail in Falcon Guide: Mountainbike Eastern New York (which is where I got the idea to ride it). It's not too long of a ride, but it is a really nice trail if you're a beginner. The first part is more doubletrack, then becomes singletrack, and slightly more difficult. It's approximately a 3 mile loop in-and-out. Gentle rolling trail, with nothing too extreme. The trail is part of a bigger network, but I did not ride the other parts yet.
Traveling East past Whiteface Ski Center on Rte. 86, the trailhead is directly past the bridge over the Ausable River on the Left.
