At low tide a causeway connects it to the community as well as at high water passenger watercrafts lug site visitors between Marazion as well as St Michael's Mount. Marazion is a successful traveler resort with an energetic community of musicians who generate and sell paints and pottery in the community's art galleries.

On the western side of the town is Marazion Marsh, a RSPB book and a Site of Special Scientific Interest (SSSI).
