A sign marks the entrance to the trail. Keep in mind only campers with reservations and visitors with disabilities are permitted to drive into the small parking area inside the gate.
Though hikers can head onto the loop in either direction, heading up the main trail and returning on the bypass reserves much of the scenic singletrack for later.
One benefit to hiking the bypass trail out and returning on the primary trail is that the trail maps list places of interest sequentially in that direction.
