Just 9km northeast of Bouctouche, Irving Eco Centre makes accessible 'La Dune de Bouctouche,' a gorgeous, powder-soft sandspit jutting into the strait. The interpretive center has worthwhile displays, but the highlight is the 800m boardwalk that weaves above the sea grass along the dunes. The peninsula itself is 12km long, taking over four hours to hike over the loose sand and back. If you're short on time, walk the boardwalk and return along the beautiful beach, taking a dip along the way.
There's a 12km hiking and cycling trail through mixed forest to Bouctouche town, which begins at the Eco Centre parking lot.
