Sandy Point Beach is in Stockton Springs and is a sandy beach (a rarity in northern Maine!) that is great for swimming, picnicking, walking, and bird and other wildlife watching. There is also a small network of trails that are a mix of dirt paths and wooden boardwalks.
From the pretty sandy beach of this state park, you can see the remains of the pier piles of an old fertilizer plant and the even older passenger steamer, the Boston-Bangor Packlet. According to the city, you can even spot seals basking on a rocky ledge in the middle of the river! The relatively short beach is perfect for a stroll, as are the trails that crisscross the park—though these can be very wet! Boardwalks have been built along most of the park's trails to keep hikers above water and mud. Even so, take care.
