Nusa Penida, the largest of the 3 Sisters Island, along with Lembongan and Ceningan, offers the chance to see turtles, shark, mola-mola, and healthy reefs in fantastic visibility. However, the currents are fast and unpredictable so you must go, not only with a reputable dive operator, but also with a guide who knows how to 'read' the currents. Most of the diving is along the north and northeast coasts and in the strait between Nusa Penida and Ceningan. Manta Point is located off the southwest of the island.
