Visitors bike, hike, cross-country ski, boat and fish.
At the Seacoast Science Center at the park, visitors learn about marine life in the center's indoor touch tank. They can also watch deep ocean fish swim in the 1,000-gallon Gulf of Maine tank. History buffs have their turn, too, on a walk that highlights four centuries of local history. Picnic tables, a boat launch, paved bicycle path and educational displays and programs round out a rich experience. There are also panoramic views of the ocean and the remains of military occupation here.
