The Aldrich Lake Loop Trail at Mount Holyoke Range State Park in Granby, Massachusetts is an easy 1.3 mile loop trail that runs around Aldrich Lake. Parking is available on Amherst st along the road by the trail head. This trail has more side trails down to the water and in different directions than I could count. The trail is wide and well maintained. It ends on Aldrich St by an old Mill, you can turn back here or continue along a road that does not seem to have much traffic at all. The mill is a hidden gem with some great views of the dam falls and the river. Follow Aldrich St back to Amherst St to complete the loop. Amherst St is very popular but its a very short walk back to the parking area.
