Silver Lake State Park, just eight miles north in Barnard, Vermont offers Swimming, Kayak, and Canoe rentals as well as Paddle Board rentals. Or you can join the locals down by the Barnard General Store at the corner of the Stage Road and Route 12. Canoes and kayaks may be launched here and the beach is small but welcoming.
Various swimming holes on the Ottauquechee River offer a fun for a quick dip if its steamy out there. The Kedron Valley Inn in South Woodstock has fresh water pond open to the public for a small fee. Chaise lounges and a sandy beach provide an especially nice place for smaller children to get used to open water swimming.
