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. And he alone is able to load passengers from Makua Beach, otherwise known as Tunnels, which is closer to Na Pali Coast State Park than is Hanalei, the base of operations for most of his competitors. Elsewhere in this issue the early history of Greff's business is discussed. The early protests of adjoining landowners were unavailing. When Greff's operations expanded, however, the protests were renewed.
