A 5 1/2 mile loop trail begins and ends in a clearing up the hill from the Basswood Island dock. The trail proceeds northeast for 1 3/4 miles to the McCloud-Brigham farm site. From there the trail follows an old logging road to the east side of the island, then swings south for 2 1/4 miles to some excellent overlooks of the main quarry area. Several large blocks of cut brownstone lie in the quarry opening and rusted parts of old equipment can still be found. From the quarry, the loop trail turns north for 1 1/2 miles through the forest to the dock clearing.
