The Rock Rift trails are the newest addition to the greater Finger Lakes Trail System. The rail trail, approximately 7.8 miles in length, is relatively flat and makes for a fairly leisurely journey through the woods. The fire tower trail is something different altogether. It is probably not advisable for novice hikers, and hiking poles are recommended. It should be noted that the fire tower itself is unrestored and closed to the public. Overall roundtrip is approximately 5-7 miles, depending on which trail entrance you choose. More information on the trail can be found here, there is an interesting brochure on the history of the area here, and a convenient map with detailed trail description here courtesy of the Catskill Mountain Club and Finger Lakes Trail Conference.
Consisting of an accessible 1.5 mile trail along the Delaware River is Partridge Island. This trail offers a fully handicapped-accessible, well-groomed walk with views of the Delaware River.
Directions to this trail head, take Fishs Eddy Exit 89 or Hancock/Cadosia Exit 87a off of Route 17/Interstate 86 and follow Old Route 17 along the river until you see the large green Partridge Island Walking Trail sign.
