The Cedar Trail at the Mount Agamenticus Conservation Region in York, Maine is an easy 2.8 mile out-and-back hike through the mostly-coniferous woods next to the mountain. There's not much to see on this trail, but it leads you into the heart of the conservation region. The trail is lightly-trafficked, but you may see ATVs on the trail as these are permitted. Biking is also allowed here.
Connector Trails: You can use the Goosefoot Trail to connect to the Ring Loop Trail, which has plenty of other connecting trails at Mount Agementicus Conservation Region.
Note: This trail can be very buggy after rainfall and during the Summer months.
