Seawall is a National Park campground. There are no hookups, but there is drinking water available and a dump station. Some sites are reserved for tents only. “C” Loop can accommodate campers snd RVs up to 20 feet, but, again, no hook ups. There are flush toilets. A bus stop is located at the entrance so you can get to other areas within Acadia NP easily. There is a rocky beach just across the road for exploring tidal pools.
