Hither Hills State Park offers visitors scenic picnic areas, fireplaces, fishing (saltwater, ocean surf casting, freshwater pond), a sandy ocean beach for swimming, playing fields, a playground, and a 165-site campground on the ocean. Anglers can fish year-round and obtain permits to fish at night. The unique "walking dunes" of Napeague Harbor are located on the eastern boundary of the park, which also has woodlands filled with Russian olive, oak, shad, and pine trees. Bridle paths and hiking, nature, biking, and cross-country ski trails are throughout the park. There are 168 tent and trailer campsites with showers, a store, dump station, and horseshoes.
