Reid State Park was donated to the state of Maine in 1946 by local businessman Walter E. Reid.
The park's sand dunes are among the few remaining in Maine that are relatively undisturbed and serve as vital storm buffers.
Griffith Head, a rocky promontory within the park, was named after the family that originally owned the land.
The park contains salt marshes that act as natural nurseries for various marine species and shellfish.
Seguin Island Light Station, visible from the park, is home to one of the highest lighthouses in Maine.
Reid State Park is the first state-owned salt water beach in Maine, featuring three-quarters of a mile of sandy coastline. The park encompasses two distinct beaches, Mile and Half Mile, separated by the rocky headland of Griffith Head. Visitors can observe nesting sites for endangered piping plovers and least terns, which are protected by seasonal fencing. The park's varied terrain includes sand dunes, ledge outcroppings, and tidal marshes fed by the Sheepscot River. It serves as a critical stopover for migratory waterfowl and shorebirds along the Atlantic Flyway. A network of hiking trails provides access to forest habitats and panoramic ocean overlooks. Picnic areas are strategically placed along the coastline, offering views of Seguin Island Light Station. The site is characterized by significant tidal fluctuations that expose large rocky pools at low tide.

Check local tide charts before arriving to experience the best rock pooling and beach walking conditions.
Bring binoculars to spot offshore seals and eider ducks near the rocky ledges.
Pack a windbreaker, as the open coastal location can be significantly cooler and windier than inland areas.
Do not attempt to walk on the fenced-off dune grasses, as they are fragile and essential for erosion control.
The park operates primarily from mid-spring through late autumn; vehicle access may be restricted or limited during winter months due to road conditions.
Leashed dogs are permitted on trails but are prohibited on the sand at Mile and Half Mile beaches during the nesting season.
