Recreation

From gentle walks along the rugged coastline, mountain hikes, tree lined carriage roads for biking and lakes for kayaking and canoeing, Acadia offers many opportunities to get outside and be active.

Park rangers at Acadia offer a variety of programs to suit every interest and activity level. Programs include walks, talks, hikes, narrated boat cruises, bike rides and more. Kids age 6-12 love Acadia's Junior Ranger Program.

A 27-mile, historic loop road system offers outstanding views of the park's ocean shoreline, coastal forests and mountain silhouettes.

Facilities

The majority of this family-oriented campground's sites are for small and large tents; some sites can accommodate RVs up to 35 ft. in length. Maneuvering RVs in the campground can be very difficult. Seawall Campground was not designed to accomodate large RVs and trailers. Please read campsite details and warnings carefully before reserving a site. Accommodations cannot be made for RVs or trailers that do not fit in reserved sites.

Flush toilets, running water and a dump station are provided, as are picnic tables and fire rings. Roads are paved. A picnic area is located on the shore across from the campground entrance.

***Fee shower facilities and camping supply stores are located 1 mile from the campground. There are no showers in the campground. The use of portable showers is prohibited.***

Natural Features

Southwest Harbor is located on the west side of Mount Desert Island. The west side of the Island is considered the "quiet side" of Mount Desert Island. All the sites at Seawall Campground are wooded and within a 10-minute walk to the ocean. There are many beautiful and quiet hiking trails on this side of the Island, as well as Echo Lake, a wonderful lake for swimming, fishing, canoeing, kayaking and picnics. Acadia is comprised of a cluster of islands on the Atlantic coast of Maine. Mountains, lakes, streams, wetlands, forests, meadows and beaches are all found within roughly 50,000 acres comprising Acadia.

Nearby Attractions

Acadia National Park is surrounded by scenic island harbors and quaint towns. Mount Desert Island, the Schoodic Peninsula, and Isle au Haut offer plenty of visitor services including restaurants, shops, museums, and tours. Please check with local Chambers of Commerce for more information.
