USGS topos are Lexington, Hunter, Bearsville, Woodstock and Kaaterskill. This is a loop hike and is about 25 miles long so it can be done with one car usually starting at Woodland Valley Campground. The view from the top of the Wittenberg is one of the best in the Catskills. There are about a dozen viewpoints, all excellent. Giant Ledges alone has about 4-5 different views from its cliffs above Woodland Valley.
Water is never a problem even during dry season.
USGS topos are Phoenicia, West Shokan, Peekamoose and Shandaken. An excellent map set for ALL the hikes in the Catskills is the 5 map Catskill Trails set. The Companion book by McAllister and Ochman is the standard hike book, an excellent addition and worth every penny.
