Walkable Westchester (old edition, update available)

The book covers over 180 parks with almost 600 miles of trails in Westchester County. It includes sketch maps of all but the smallest parks. Public transportation options are included where available. There is extensive history of the parks and the people involved. Icons show parks suitable for the handicapped, bikes, horses, dogs and cross country skiing. Many parks have photos that show what to expect to see when you visit. The parks are arranged by size classes and have a locator map to show approximately where they are in the county. Westchester.nynjtc.org has additional information and some suggested hikes.
