Blueberry Island

Owned By: Town of Marshfield

4 acres of upland surrounded by 12 acres of marsh owned by the Town of Marshfield. A popular picnic area. Camping by reservation. Apply for a permit at Marshfield’s Conservation Office. Water access only.

IMPORTANT: Please “leave no trace,” and carry out all trash and waste. Careless overuse is endangering this much-loved spot!

Little Blueberry Island, considerably smaller but also inviting, is located just a little bit farther upstream.


Just upstream from Couch Beach, Blueberry Island is a worthy destination for those traveling by canoe or kayak. There are two access points to the boomerang-shaped island. One in on the island’s northern tip and one is on the southern half, facing Norwell. Pull up your boat and pause for a snack or to stretch your legs. The water access point for Little Blueberry Island, a little farther upstream, also faces Norwell.

In earlier days, Blueberry Island and Little Blueberry Island were known as Onion and Potato Island. The larger island, Onion, often had cattle pastured on it.

Trail Description

Blueberry Island is only 4 acres, but it’s a fun place to explore. Trails lead in two directions — one to the top of a hill overlooking the river valley, and one along the island’s outer perimeter. Be on the lookout for poison ivy!

Access Blueberry Island on foot is not recommended, as it requires walking over sensitive marsh habitat.

Habitats and Wildlife

Blueberry Island and Little Blueberry Island are both small upland forests surrounded by marsh. In season, look for wild blueberries growing in the upland forest, especially on the hill.

White tail deer are commonly spotted in the marsh along the forest’s edge.
