Put your paddling skills to the test this summer by joining Jug Bay Wetlands Sanctuary for a paddle on the Patuxent River, Maryland's longest and most beautiful river. The Patuxent River Paddle-A-Thon will feature an 11 mile paddle. Paddlers are encouraged to bring their own gear, however, there are a limited number of kayaks, canoes, paddles and PFD’s (personal floatation devices) for rent.
