Nusa Lembongan is an island located southeast of Bali, Indonesia. It is part of a group of three islands that make up the Nusa Penida district, of which it is the most famous. This island group in turn is part of the Lesser Sunda Islands.
Nusa Lembongan is approximately 8 square kilometres in area with a permanent population estimated at 5,000. Twelve kilometres of the Badung Strait separates Nusa Lembongan from Bali Island. The island is surrounded by coral reefs with white sand beaches and low limestone cliffs. Nusa Lembongan is separated from Nusa Ceningan by a shallow estuarine channel which is difficult to navigate at low tide. There are no permanent waterways on Nusa Lembongan. There is a suspension bridge linking Nusa Lembongan and Nusa Ceningan which takes foot and motorbike traffic only.
