Peter Igo Park

29 Marshall Ave #1, Marshfield, MA 02050, USA


Owned By: Town of Marshfield

Town-owned park with athletic courts, a small playground, and access for non-motorized boats and rowing shells to the Green Harbor River. In season, there is a small pier with floats directly on the river and an all-access launching ramp. Also accessible via the Harbor Walk.


Named for Marshfield’s first Director of Recreation and dedicated on July 3, 1976, this park was renovated and updated in 2014. Maintained by the Friends of Peter Igo Park, a registered 501(c)3 non-profit. Before its transformation to parkland, it was a landfill, sometimes known as the Brant Rock Dump. Also of note: for part of the 20th century, a Horton Sphere, storing compressed gas, stood on the site of the park.

Canoe and kayak rentals, provided by the Marshfield Recreation Department, are available on site with advanced registration. To book, call or text Dan McDonald: 781-837-8212.

Home of the Marshfield Tennis Club, the park also features 3 regulation tennis courts,  4 “10 and under” tennis / pickle ball courts, plus 2 regulation bocce courts, a basketball court, beach volleyball, horseshoes, and street hockey. Borrow a bocce ball or a volleyball at the DAV across the street from the park.

Peter Igo Park is also the headquarters of Green Harbor Rowing, which offers rowing shell lessons for juniors and adults. For details, visit

According to information posted at the park, Everson Island did not appear on the 1795 local map, but it was present on the 1872 map. Local lore indicates that the island is composed of Saco soil, found only around Saco, Maine. The prevailing theory is that schooners transporting lumber from Maine to T.B. Blackman’s lumber yard on the Green Harbor River used the Saco soil as ballast. The island received its name from Erastus Everson, a writer who built a small house there c. 1894.

Trail Description

No trails within the park, however just a few steps away is the Harbor Walk, a concrete walkway that extends from the Marshfield Town Pier to the Brant Rock Esplanade, as well as past the Green Harbor Marina to Careswell Street (just over 1 mile total).

Padding Tips: Paddlers can really only head upstream here, as the Brant Rock Dike (under Route 139/Dyke Road) prevents boats from traveling downstream. In the middle of the river, close to the launch area, is the 1.9-acre Everson Island. It is privately owned, but respectful visitors are welcome to explore. It’s easiest to land your boat on the far side (south) of the island.

Heading upstream, when you arrive at the first fork, Wharf Creek is to the left, and the Green Harbor River is to the right. You can paddle up Wharf Creek for a bit before it gets too narrow and shallow. Continuing up the Green Harbor River, at the next fork, Bass Creek is to the right, and the main channel of the Green Harbor River is to the left. (For the average paddler, this junction is about an hour from Peter Igo Park.)

You can continue paddling quite a way up Bass Creek before it becomes difficult to navigate. If you continue on the Green Harbor River, you will reach the two bridges of Mass Audubon’s Daniel Webster Wildlife Sanctuary. The river channel narrows, but you can continue for another hour or so, almost to Webster Street. Just remember, you will have to paddle all the way back. There are no upstream launch spots on the Green Harbor River.

Habitats and Wildlife

The Green Harbor River, and one of its major tributaries, Wharf Creek, flow through this property. The Green Harbor River finds its source in springs and ponds in Duxbury. It twists and turns through Marshfield via large cranberry bog complex, the Green Harbor Golf Club, the Daniel Webster Wildlife Sanctuary, property owned by the Marshfield Municipal Airport and Peter Igo Park. Just downstream of the Dyke Road bridge (and dike) it flows into the Atlantic Ocean at Green Harbor.

There are usually at least two osprey nests visible from the portion of the Green Harbor River below Bass Creek. Osprey activity can be quite captivating. Be especially respectful during (spring) nesting season, and do not approach closely. Other birds commonly observed here include snowy egrets, red winged blackbirds, Baltimore orioles, bald eagles, cooper hawks, and bobolinks. Upstream, it is common to see great blue herons. Some of the fish commonly found in the river include striped bass, white perch, American eel, alewife herring, as well as blue crab.
