Paddling in Boston Harbor Islands National Recreation Area

Boston Harbor Islands National Recreation Area is an archipelago of 34 islands and peninsulas scattered across the outer reaches of Boston Harbor, sitting where the city's working waterfront meets open Massachusetts Bay.

The paddling here is saltwater touring — ocean kayaking and canoeing across tidal channels, exposed crossings, and sheltered bays — with the skyline at your back and the Atlantic ahead. Most trips originate from the mainland.

The bays at Quincy and Hingham offer the most forgiving conditions for paddlers working their way out to the islands, with shorter crossings and more protection from the open harbor's chop.

Bumpkin Island, a 62-acre island in Hingham Bay, is a natural destination for overnight trips — paddlers who camp there can rent boats by the day from outfitters operating out of Kendall Square in Cambridge.

Peddocks Island, one of the largest in the harbor, is another reachable destination with public moorings available for reservation. Lovells Island draws fewer visitors than the more central islands and rewards paddlers willing to make the crossing.

The harbor's conditions demand respect. Currents can exceed 2 knots, and conditions beyond Fort Independence at Castle Island escalate quickly — steep short-period waves, fog, and reduced visibility are all real possibilities.

Boat traffic is the sharpest hazard: ferries, private powerboats, and commercial vessels including supertankers share these waters, and the larger ships cannot stop or easily see a kayak.

Paddlers are advised to carry proper safety flags and stay alert to vessel traffic throughout any crossing. For emergencies on the water, the US Coast Guard monitors VHF Channel 16.

Response times to the islands run significantly longer than comparable distances on the mainland — self-rescue capability is not optional here, it's the baseline. The harbor is mid-cleanup.

A current initiative led by the Massachusetts Department of Conservation and Recreation and the Center for Coastal Studies is removing marine debris from Great Brewster, Middle Brewster, Outer Brewster, Calf, and Lovells Islands.

The water quality that makes this paddling worth doing is the result of decades of restoration work — and it's still ongoing.
