To visit the Clove, the best place to park is at the circle on Indian Trail Drive in Franklin Lakes. (Type "595 Indian Trail Drive Walk" into Google Maps.)
Walk into the preserve about a third of a mile. At the T, make a left to go to Buttermilk Falls and to the right to the Clove. Wear shoes with ankle support and bring a walking stick, water and a cellphone in case you get lost.
