The Greenwich section of PEI National Park, about 15 kilometres west of Naufrage, protects one of the finest dune systems in the Gulf of St Lawrence and a long stretch of uncrowded beach. A 4.8-kilometre trail through forest and over a floating boardwalk across a lagoon reaches the beach and dunes. The walk is flat and easy, taking about 90 minutes return.
Greenwich beach is wide, clean, and sheltered from the open gulf by the dune system, making it calmer and warmer than the north shore beaches. In July and August the water temperature is comfortable for swimming. The lagoon alongside the boardwalk trail is good for kayaking and is one of the better birdwatching spots in Kings County, particularly for herons and shorebirds.
