We stayed here in early April after making a last minute reservation (by phone only). Only a couple of spots were open. You need to be a active or retired military member to enter the base and stay at this campground.
We stayed at one of the RV loops with our van. Most rigs were large RVs, many looked like they were there for an extended stay (up to 30 days). There is also a tent-only area.
The setting is incredible right over a bluff overlooking the Sound. The grounds are immaculately maintained, bathrooms are sparkling clean, there are showers as well. Several picnic areas and firepits some covered, swings and outdoor games (giant chess, corn-hole). A lovely paved waterfront trail on the bluff and then an amazing sandy beach. At low tide, you can walk all the way to Rocky Point and beyond outside of the base.
Air force planes fly right above so it can be noisy (but also exciting) when they are flying by. Decent WIFI throughout the campground, better in some places. Poor AT&T cell reception.
