The Seven Hills Trail is one of the most challenging but beautiful trails in Harriman. As you might guess from the name, it is very hilly. Several of the ascents are scrambles and involve using your hands. The ascents and descents come one after another, making it challenging to keep a good pace or rhythm. With that said, the views are excellent on all of the peaks and it is worth all the effort. The trail starts from near Ramapo Torne and ends near the east side of Lake Sebago.
