Suffolk County’s Green Key is more than a park card. It identifies the holder as a Suffolk County resident, gives access to county parks, and provides reduced fees for park activities. It is also required for the online reservation system for camping and marina reservations, and is good for three years from purchase. Outer beach access has its own 4x4 permit route, sold year-round at listed offices and online, with in-season sales at some beach offices.
Before booking camping or a marina, make sure the active Green Key is tied to the account making the reservation. For an outer beach trip, use the separate 4x4 permit route and check current beach conditions. The Green Key, reservation account, outer beach permit, and park status answer different parts of the plan.
