Sand Beach is a 290-yard ocean beach tucked into Newport Cove between Great Head and Otter Cliffs, along the Park Loop Road coast. It’s Acadia’s largest sandy beach, and one of the stops I’d keep on an ocean-side day: settle on the sand, walk the surf line, or use it as a starting point for a longer coastal outing. The Atlantic here is cold, usually 50–60°F (10–15°C) even in summer, and strong tides and rogue waves can surprise swimmers. If you’d rather stay dry, the cove is still a good place to slow down and watch the water.
