Cardigan Bay is a coastal bay on the eastern side of Prince Edward Island, Canada, forming the marine estuary for the Cardigan, Brudenell, and Montague Rivers, collectively designated as the Three Rivers National Heritage River System. The bay opens to the Northumberland Strait and is characterized by its connection to a network of placid tidal streams and feeder rivers. Paddlers can access the bay from several points, including the town of Georgetown and MacPhee Beach. The village of Cardigan, with its marina, provides a practical launch point, offering 24/7 access to a marina washroom and shower facilities for paddlers, along with free public parking. The overall character is one of a working maritime landscape, with views of a marina, oyster farms marked by rows of small floats, and colorful fishing boats. The surrounding area features sandstone cliffs, beaches suitable for walking and swimming, and mixed forests. Wildlife sightings include seals, seabirds, and blue herons. The bay's waters lead to sheltered anchorages like St. Mary Bay, peaceful and protected. Given the tidal nature of the feeder rivers, paddlers must plan for tidal currents. The area is exposed to the open waters of the Northumberland Strait, meaning wind and wave conditions can develop, requiring appropriate skill and preparation. Boat traffic from fishing vessels and the presence of aquaculture operations are notable considerations for route planning.
