Nusa Penida is the largest of three islands off the south eastern coast of Bali, the others being Nusa Lembongan and Nusa Ceningan.
With an area of 247 km², Nusa Penida is much larger than the better known Nusa Lembongan. However, tourist infrastructure is not as advanced as Lembongan. It is an island of outstanding natural rugged beauty. The north shore is the most densely populated part of the island and is where most tourism is based. This is also where the beaches are and where the seaweed farms are. Seaweed farming started on the island in the 1980s as a way for locals to get an income. Sadly prices are declining and so is production. Most locals still derive their income from subsistence farming.
