Seawall Campground at Acadia: Watch This Before You Book on the Quiet Side

Worth a stop

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.

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.

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.
