Mavillette Beach Provincial Park, located two kilometres from the Cape Saint Mary Lighthouse Park, is a 1.5 km long sandy beach backed by fragile marram grass-covered dunes protected by boardwalks. Low tide exposes sand flats; then the hot sand warms the water.
Supervised swimming on Saturdays and Sundays in the months of July and August, the park facilities include change houses, vault toilets, freshwater taps, interpretive panels, and three parking areas and boardwalks to access the beach.
