Owned By: Town of Weymouth

Unusually rocky property with a challenging 0.7-mile loop trail.

Features

Cavern Rock Park was acquired as conservation land by the Town of Weymouth in 1968. It features numerous rocky outcroppings, many covered with moss. Deep within the property, don’t miss the old stone wall — it extends for quite a distance!

Trail Description

This property features a 0.7 mile loop trail. It is quite rocky. It is also quite steep in places, offering a more challenging hike than what is typically found in the area. The trail extends through the forest, between and over some large rock formations. While rocky, it is not “rock climbing” terrain (no need for ropes or carabiners). The trail is marked with white blazes.

Habitats and Wildlife

The forest here is primarily oak, with some maple, beech and black walnut, plus pine and the occasional hemlock, and plenty of greenbrier. The lands here drain to Whitman’s Pond nearby, and lie within the watershed of the Weymouth Back River. The Weymouth Back River flows for about 10 miles through Weymouth, and empties into the Atlantic Ocean at Hingham Bay, just south of Grape Island and Slate Island.
