The island is a limestone plateau with a strip of sand on its north coast and views over the water to the volcanoes in Bali. The south coast has 300m-high limestone cliffs dropping straight down to the sea and a row of offshore islets – it's rugged and spectacular scenery. The interior is hilly, with sparse-looking crops and old-fashioned villages. Rainfall is low and parts of the island are arid, although you can see traces of ancient rice terraces.

Beaches are very few although some are spectacular.
