The Northern Headwaters Preserve includes vast areas of peaceful forest rich with birdsong, and several chances to meander along the trickling Sheepscot River at its beginnings, where the stream here is excellent rearing habitat for Brook trout and Atlantic salmon.

From the trailhead, visitors can access the Hemlock Hollow trail on either side of Halldale Road. The western end of the trail twists its way up through a mature mixed forest from Halldale Road to the Northern Headwaters Trail and north to the Goose Ridge Trail.

On the east side of the road, Hemlock Hollow Trail skirts the edge of a sublime, hemlock dominated ravine, eventually crossing this uppermost section of the Sheepscot in a quiet, mature mixed forest. The eastern end of the trail is at the junction with the Hogback Connector Trail.

These trails also are part of the Hills-to-Sea trail, stretching from Belfast to Unity


From the South: From Rte 3 in Liberty, take Route 220 North about 3 miles and turn left on Burnham Hill Rd/Halldale Rd (road curves sharply to the right here and street sign says “Mountain Valley Hwy”). Stay to the right at the fork in the road to continue onto Halldale Rd. Continue 2 miles to the trailhead sign on your left; parking is along the road.

From the North: From Rte 137 at Knox Ridge, take Route 220 South 1.8 miles. Where 220 curves sharply to the left, continue straight onto Halldale Road. Continue 2.8 miles. Just past a cemetery on your left, the trailhead sign will be on your right; parking is along the road.
