The park mostly consists of a geological formation known as a winding ridge of stratified sand and gravel formed by a glacier 12,000 years ago.

It is located along the Weymouth Back River, across from Bare Cove Park in Hingham, Massachusetts.

[1] The park features the highest esker in North America (90 ft), reversing falls, salt marshes, six miles (10 km) of trails, a playground and picnic area.

Bird watching is a popular activity as osprey, great blue heron, red-tailed hawks, owls, and other species of birds are abundant seasonally.

There are man-made shelters on the river where Osprey nest in the spring and summer months.
