Lewis Rocks is a 1,729-foot-tall popular scrambling and bouldering area in southern Pennsylvania. The trail to the rocks starts close to where the Tumbling Run and Mountain Creek trails meet. It is almost flat for the first 10 minutes. It runs through lovely ash and oak forests and dense bushes of fragrant mountain laurel. As you get higher, there are several trails that run parallel to Tumbling Run. Keep the stream always on your left as you go up and you will not go wrong whichever trail you choose. You will see a number of waterfalls and small pools along the way. The higher you go, the steeper and rockier the trail gets until you reach Lewis Falls. Follow the path to rocky formations on the ridge until you reach the summit. Spectacular views of the South Mountain will open up in front of you.
