There are 20 tent sites spread across four loops. There is NO beach access. Some sites have shelters, others do not. Pay attention when reserving. All sites have a fire pit and picnic table. Sites are walk-in (only about¼ mile) and carts are available to haul gear. Two water spigots and bathrooms with flush toilets are also on-premise. No electric, hook-ups, or showers. The nearby beaches have outdoor shower facilities though. The racoons are fierce. They will eat through your tent. Use the bear lockers provided to store anything scented. 

Activities abound: hit the beaches for (non-motorized) water sports or sunbathing (Gunnison is the nude beach), learn about the military history of the area on an NPS tour, visit the oldest working lighthouse in the US, walk or bike the multi-use trails, go birding, and more! Nearby Hartshorne Woods Park (Monmouth County Park System) has great hiking and mountain bike trails too.
