Haseltine is a parcel of property owned by the Amherst Conservation Commission. The land is a hilly deciduous-conifer mix forest with sections of glacial erratics. The trail varies from double track to single track. In places the trail is very rocky and technical while in others the trail is fast and smooth. The main trail is marked with white rectangles and is a loop. The main loop is hilly with 3 bridges, and a set of switchbacks. The Raven trail is marked with red rectangles and travels through the middle of the main loop. The Raven trail is more challenging and offers a variety of optional drops, log rolls, and a plank. There are around 4 miles of trails at Haseltine.
