Crystal Bay is the gentlest of Nusa Penida’s famous coastal spots, a sheltered horseshoe of white sand and clear water on the island’s northwest coast. Most of Penida is cliffs seen from above; here you can actually get in the water. Swimming is easy, the reef sits close to shore, and the bay has a name as one of the island’s best snorkelling and diving sites. A small rocky islet topped with a shrine guards the mouth of the bay, framing the view and marking the deeper water beyond.
Swimming and the beach
The inner bay is calm and shallow near the sand, which makes it one of the safer beaches on an island better known for rugged coastline. The water clears to the pale blue that gives the bay its name, and the palm-backed shore is lined with warungs renting sunbeds and serving food and drinks. Currents strengthen toward the open sea and around the islet, so it is wise to stay within the bay and to treat the water with respect, as there are no permanent lifeguards.
Snorkelling and diving
The snorkelling is the draw, with a reef within easy reach of the beach and masks and fins for hire on the sand. Below the surface, this is also one of Bali’s premier dive sites, best known for the mola mola, the oceanic sunfish that rise from deeper, colder water around the middle of the year. Seeing one is a diving job rather than a snorkelling one, and sightings are seasonal and never guaranteed, but the reef and marine life reward a visit at any time. The currents and cold thermoclines here suit experienced divers.
The setting
The bay faces west, so it can also serve as a place to end the day, though its main draw is the water rather than the sunset. The rocky islet at the entrance, with its small shrine, is a distinctive feature and a marker of where the sheltered water gives way to the open channel. Facilities are simple, with warungs and parking near the beach and little other development.
How to visit
Crystal Bay is about 30 minutes from the harbour on the northwest coast, reached by scooter or a hired car and driver over the island’s rough roads. Mornings bring the calmest water for swimming and snorkelling. It pairs well with the cliff viewpoint at Kelingking Beach and the west-coast sights on a full day.
