Tatamagouche Bay is a coastal bay on the Northumberland Strait in Nova Scotia. The name derives from the Mi'kmaq term for "Meeting of the waters," and the bay is situated near the village of Tatamagouche. The bay is part of a coastline characterized by sandstone cliffs, pocket beaches, and sand spits. The bay itself presents significant open-water crossings for paddlers; one account details a planned route involving two major crossings within the bay, one of 2.5 miles and another of 3.2 miles. These open stretches can become hazardous in wind, with conditions capable of whipping up whitecaps and streamers, requiring careful seamanship. The broader Northumberland Strait coastline here sees minimal commercial boat traffic outside of lobster season, with mostly small outboard sport fishing boats present.

For access, paddlers can utilize several points near the village. Patterson’s Wharf and Nelson Memorial Park, which overlook the bay, are directly accessible from the Trans Canada Trail system. The trail itself, also known as the Short Line Trail, runs along the south shore of the bay, providing a multi-use path that connects to these access points. North Shore Adventure Outfitters, located on Main Street in Tatamagouche, offers kayak and paddleboard rentals, facilitating trips onto the bay. Nearby Rushton’s Beach Provincial Park and Blue Sea Beach Provincial Park feature broad sandbars and long sandy beaches, which are accessible at low tide and could serve as potential landing spots. Paddlers should be acutely aware of tidal influence, wind exposure over the long fetches of the bay, and the potential for surf on beach entries, particularly at the provincial parks. The area is known for wildlife, including gray seals hauled out on ledges off points like Oak Island and Schooner Point.
