I recommend doing the hike counter-clockwise starting from the Family Campground at Rt. 154. That means completing the loop with a stretch of level hiking beside the Loyalsock Creek, making for a very nice finish. The view at the canyon lookout is well worth the effort and be sure to check out the nearby Rock Garden, an impressive jumble of huge boulders and rock formations! Just long and strenuous enough, with visual treats along the way, to make it a very enjoyable and rewarding hike!
