The Stone Lodge Loop Trail at Keystone State Park, Pennsylvania, is a moderate 1.6 mile out-and-back loop hike that starts at the visitor's center, heads up the hill behind it, before heading back.
Along the trail are the remnants of an old homestead, but we were not able to find anything during the Summer. The Fall or Winter may be better seasons to find the old homestead.
This trail is fairly moderate since it shoots up a large hill quickly for the first 0.5 miles or so before a "rollercoaster" of ups and downs before looping back to the main uphill climb.
Dogs are allowed here, but no biking. Follow the yellow blazes and stay left or stay right to continue on the trail. There are a couple connector trails that cuts between the main loop, so check your map at each intersection.
