Pritty safe in terms of geting lost, most of the trails loop back on to the main trail, but their are no signs. If you don't like bugs don't hang around long when your down in the swamier areas but hey that's the only place you'll find big hills so... Moter vehicles aren't alowd.
Go to the Colchester High School Parking lot; the trails start in the far right hand corner of the main parking lot as your comming in.
