House Rock Park

House Rock Rd, Weymouth, MA 02188, USA

(781) 682-6124

Owned By: Town of Weymouth

Small park with hiking trail and impressively large freestanding boulders.


This small town-owned park is centered around one very large glacial erratic boulder, House Rock. The property, located at the end of a residential street, also features a small playground, a basketball court, an open grassy field, and a 0.34-mile woodland loop hiking trail.

According to the Town of Weymouth, House Rock is considered one of the largest freestanding boulders in New England. Very likely it was deposited here 10,000 years ago by a retreating glacier — the same glacial retreat that created the 90-foot-high esker at North Weymouth’s Great Esker Park.

Trail Description

The 0.34-mile trail begins behind House Rock itself. Follow the white blazes into an open forest that is composed primarily of oak and pine. A footbridge leads over a dry stream, and then the trail continues up and down some moderate hills, looping around upon itself at the end.

Habitats and Wildlife

The woods here are primarily oak, with some pine and pitch pine scattered here and there, plus some greenbrier. The property lies on the border line between the Weymouth Back River watershed and the Monatiquot River watershed. The front section of the park itself drains southeast to Whitman’s Pond, but the rest of the property drains northwest, toward Tide Mill Brook and the Monatiquot River.
