The best way to enjoy this place is to have someone show you around; ideal trails in ideal directions, etc. If not, I would strongly recommend uploading someone's garmin file. Too many unmarked options to get one turned around.
There are three typical spots to start from; 1) Tranquility Side off Rt. 517; 2) Sussex Branch off Waterloo Road & Continental Drive; or 3) The Park n' Ride lot in front of Cranberry Lake off Rt. 206.
