Led by DPNC naturalists, the Pequotsepos Hiking Club meets twice a month, on a Tuesday and Saturday. This week, they head to Devil’s Hopyard, one of Connecticut’s most beautiful state parks, with a waterfall cascading into the eight Mile River, wooded ravines and beautiful views. To carpool from the Mystic area, call Denison Pequotsepos Nature Center at (860) 536-1216. Older children and babies in front or back carriers are welcome; steady rain cancels.
