Several tours are available.
Most include snorkeling stops, with boats anchoring in the coral heads off beaches that are inaccessible by overland routes. More expensive tours include landings on the beaches, with a picnic lunch provided. The return trip, usually against prevailing winds, may be likened to an amusement park ride in one of the world's loveliest settings. Passengers scream as the boat pitches and rolls on steep waves, but the chance for harm is minimal. Size and site set Greff apart from other tour operators.
