New Brunswick is surrounded on three sides by water — the Bay of Fundy on the south with its world-record 16-metre tides, the Gulf of St. Lawrence on the northeast with its warm beaches and Acadian fishing communities, and the Northumberland Strait separating the province from PEI.
The province packs ocean coastline on three sides — with the Bay of Fundy's extraordinary tidal drama on the south, the warm Gulf of St. Lawrence beaches on the northeast, and a river-laced Appalachian interior that transitions between them — into an area that a campground circuit can meaningfully cross in a week.
Kouchibouguac's Gulf beaches are warm enough for swimming from July. The park's lagoon supports a significant grey seal colony visible from the barrier beach, and the cycling trail network through the dunes and marsh is outstanding for families.
Mount Carleton Provincial Park in the center of the province's Appalachian highlands offers a completely different experience — remote highland camping, the highest peak in the Maritime provinces, and some of the best dark sky conditions in New Brunswick.
