On the south shore of Long Island, Moriches Bay is protected by Westhampton Beach barrier island. The water here is calm, clear, and warm. Perfect for watersports, local rental and excursion businesses offer fishing, sailing, kayaking, andpaddleboarding. Where to camp? From Westhampton Beach, head all the way down Dune Road to Cupsogue Beach County Park. (The ocean beach is also a gem.) You may still be able to get a campsite on the beach if you go during the week. Permits are required andreservationsmust be made in advance.
