A droplet of creamy white sand, topped with a tuft of scrub, this island jewel set offshore from Java, nearly halfway to Bali, is surrounded by a ring of turquoise shallows with a deep blue drop-off about 50m from shore. You'll see bait balls, schools of tropical fish and decent coral structure. The water is aquarium clear, and from the beach the volcanoes and mountains from Java and Bali are spread out in all directions.
Though the winds can rip (there's a reason an annual kite-surf contest is held here), it's possible to camp. If you do, you're likely to have the place to yourself. To get here, take a taxi or ojek to the Rumah Apung port, north of the ferry terminal, and hire a boat from there. It's 400,000Rp to 500,000Rp round-trip.
