From the parking lot of the campground, go through the field to the west towards the gate. Past the gate, go right on the road, then left on the trail. After several hundred yards going downhill, you'll come to a fork; take a right. Follow this back uphill for another few hundred yards, and then you'll come to the fork where the Blue Trail
ends and Yost Ridge Trail
starts. You can go right down the stone steps to take the Yost Ridge Trail
or left towards the Welcome Center.
