The currents flowing around the islands are strong, and the passages between them shallow which makes it impossible for larger ships to appriach the islands. Well-protected anchorages for yachts are in the port of Palmižana. The largest island in the group is St.Clement. Beautiful coves with sandy and pebble beaches along with the crystal-clear sea attract numerous tourists and excursionists, and especially boatmen. The small islands enable diving, underwater fishing, swimming and water sports. Rides on taxi boats between Hell's islands and the island of Hvar, produce a special charm and atmosphere.
