The Grand-Mere is a calm water bay cruise to Shell Island. Enjoy a relaxing and fun-filled 3.5-hour cruise on our air-conditioned double-decker boat through St. Andrews Bay, home to one of the world’s largest resident populations of bottlenose dolphins. Take in the beautiful scenery as we sail through St. Andrew's Bay, pull fish and crab traps, look for pods of dolphins in the pass, and head to Shell Island, an undeveloped 7-mile barrier island abundant with coastal creatures such as shorebirds, ghost crabs, deer, and a serene coastal lake that is a haven for hundreds of species of plants and wildlife. See dolphins, collect shells, and walk the beautiful beaches of Shell Island.
