Reid State Park
Mile and Half Mile beaches are rare expanses on Maine’s rockbound shore, while tidal lagoon, dunes, and ledges create several distinct habitats.

Artwork inspired by Jamie Wyeth
Long sand beaches, dunes, marsh, and rocky headlands share one coast. Mile and Half Mile beaches are rare expanses on Maine’s rockbound shore, while tidal lagoon, dunes, and ledges create several distinct habitats. The park demonstrates how dynamic a beach system remains.
Walk from sand to headland and back, noting where wind, tide, and vegetation reorganize the shoreline. Cold water, surf, nesting areas, fog, and high-season parking limits matter even on calm-looking days. At Reid State Park, route choice and environmental conditions matter more than headline mileage or a single map pin. Leave enough time to revisit dune system; its quieter evidence often becomes more useful after Mile Beach has established the place.

- Connect the story
