Sunday.  Celebrate the full Beaver Moon a day early! We’ll explore the trails at Salem Land Trust’s Walden Preserve, looking for signs of beavers while waiting for the moon to rise. Bring a flashlight and meet at Walden Preserve on Hagen Road in Salem, CT. This is a hike of moderate difficulty for adults and older interested children. It is free for both members and non-members, advance registration is required.
