Abigail Adams State Park

Southfield, where the naval aircraft base used to be, now has a dog park.

Hiking trails, a 1912 sandstone observation tower, and seats may be found in this 117-acre woodland park.

The Town of Thompson's Field purchased 57 acres in 1984, which is now known as the Thompson's Field Conservation Area. Groundwater running toward the adjacent public wellfield was mostly protected by the mosaic of woodlands and farmland.

Much of this land is thought to have been purchased from the Saquatucket Native Americans in 1668 by pioneer John Bell. The land passed through several owners before being purchased by the town over 300 years later to safeguard the Herring River, West Reservoir, and surrounding woodlands.

The Harwich Recreation and Youth Department's facilities and programs are open to all Harwich residents, both adults and children.

A late-19th-century English-style stone castle and walking trails may be found in this lakeside public park.
