The John P Saylor Trail is a very mellow trail that is laid out as a double loop trail on the Plateau of Galliztin State Forest. The first loop is roughly 12 miles and consists of a fun, but severely vandalized rock outcropping. A very nice bridge connects the smaller, 6 mile loop to the south. This loop is a bit more remote and covers a nice section of the Clear Shade Wild Area. This is a nice trail for beginners, but do beware of wet conditions during the spring and early summer.
