Vaill Island Beach
Not many people think of Vaill Island as a beach spot, due largely to all the incredible beaches on Long Island. But if you’re looking for your own secluded beach close to Portland, Maine, Vaill Island will deliver.
Tucked just off the coast of Long Island, Vaill Island is a small, quiet spot that’s perfect for a peaceful stopover. With gentle shoreline, grassy interior, and views of Portland, Maine, it’s a favorite for paddlers, picnickers, and anyone looking to anchor for a laid-back lunch or a quick swim.

Note: Vaill Island is open to the public starting July 1st each year to protect nesting birds. Also it’s recommended you visit Vaill Island only on calm days given it’s exposure to the ocean.
Surprise Beach, Jewell Island
Most people stumble upon Surprise Beach, well, by surprise, while hiking around Jewell Island. But most locals avoid the crowds at Cocktail Cove by heading directly around the north eastern corner of Jewell Island to Surprise Cove.
Tucked away on the northern edge of Jewell Island, Surprise Beach is a quiet crescent of sand and stone with views across Casco Bay. It’s a peaceful, lesser-known spot that’s perfect for a swim or a beach picnic. It’s a favorite hidden corner of the island.
Note: there’s only room for 2-3 boats max, so arrive early to get your spot.
Northeast Cove, Birch Island
Tucked into the northeastern corner of Birch Island, this quiet cove offers an easy, all-tide landing for small boats. The gently sloping beach is a perfect spot to wade in, launch a swim, or set out on foot to explore the preserve’s loop trail. With a picnic table nearby and a small shed for shelter, it’s a great place to pause — or pitch a tent and stay the night. Simple, peaceful, and surrounded by the sounds of the bay.
Sandbar between Ministerial and Bates Islands
This sandbar is located between Bates and Ministerial Islands. While the islands themselves are privately owned and public access is not permitted, this beach is still one of the most scenic backdrops for a beach picnic or on-the-water lunch stop.
Protected coves, sandy beaches, and shallow ledges make it easy to anchor nearby and take in the view. In calm conditions, it’s a great spot to pause for a boat-based picnic, watch for seabirds, and enjoy the stillness that defines this corner of the bay.
Upper Goose Island
At low tide, this quiet stretch of sand and stone on Upper Goose Island’s northeast side offers a rare chance to step ashore — briefly. The island is privately owned and home to one of New England’s largest heron rookeries, so respectful, low-impact visits are key. It’s a peaceful spot to pause, beachcomb, and take in the wild beauty of Middle Bay before the tide returns.
Note: because you’re not allowed on the island, plan to visit this beach only during low tides.
