Overlook Mountain: This hike is one of the most spectacular hikes in all the Catskills because of its many facets. The trail takes you through the ruins of a turn of the century grand hotel, a fantastic overlook at the summit, and a firetower with incredible 360º views. Giant Ledge: The trail is in Big Indian and well worth the trek. It’s just a little over an hour to the top, where surreal views from multiple giant ledges await. Kaaterskill Falls: This is a short hike that takes you to the highest two-tiered waterfall in New York State.
