Lamoine State Park is a 55-acre oceanfront park in the town of Lamoine, on the shore of Frenchman Bay about eight miles southeast of Ellsworth via Route 184. Its central Downeast location gives campers easy access to Bar Harbor, Mount Desert Island, and Acadia National Park, with views over Frenchman Bay and its islands.
The campground has 62 single-family sites for tents, trailers, and RVs (up to 45 feet), most reservable with some first-come, first-served. Two tent-only group sites can be combined. Amenities include drinking water, flush toilets, hot showers, an RV dump station, a picnic area, a playground, and a trailered boat launch.
Natural Features and SceneryLamoine State Park campground sits on a small peninsula projecting into **Frenchman Bay / Mount Desert Narrows**, offering an **oceanfront setting** with forested campsites and direct shoreline access[1][3][4][6][7]. Many descriptions emphasize that the campground lies in a **grove of trees right up next to the water’s edge**, with a beach exposed at low tide for walking and exploring[6]. From the shoreline and some campsites, visitors can see **Mount Desert Island and the mountains of Acadia National Park across the bay**, providing classic Downeast Maine coastal views[1][2][3][9]. The park combines **mixed coastal forest**, grassy openings, and a pebbly/rocky tidal shoreline, giving a blend of shaded sites and open vistas[1][3][5]. The surrounding waters of Frenchman Bay are part of a larger **marine ecosystem** with tidal flats, seaweed‑covered rocks, and intertidal life that can be observed at low tide (crabs, shells, etc.), which several travel writers highlight as ideal for beachcombing and children’s exploration[2][5]. Because the park is slightly removed from busier tourist centers yet still close to Ellsworth and Bar Harbor, many campers appreciate the sense of a **quieter, more relaxed coastal environment** with dark skies, sea breezes, and the sound of water, while still being near major attractions[1][3][5][6].
