No number. First come first serve. There is usually an open space there or close by. Come early on a holiday though.
No reservations system for Cedargrove, first come first served basis. Unmanned pay station located by camping site 3 (i think its 3), be sure to take cash, $5.00 a night. If you are uncomfortable going without reservation, check out Montauk State Park, its the closest campground to Cedargrove.
It's a pay as u get there kind of thing
