Nusa Lembongan is a pristine tropical island, its highest point is 50 meters above sea level. Lembongan has an average rainfall of approximately 1000 mm per year. Little temperature variation from 30 degrees Celsius occurs between the only two seasons this island experiences being the wet and the dry. The wet season is from December to February and the dry is from March to November. As it has only three months of rainfall, this island is dry for the remainder of the year. Little cultivation occurs, as almost 2/3 of the island is infertile. Seeding is normally done on the wet season and only corn, cassava and peanuts are farmed. Also found on the island are cashew nuts, mangoes and coconut. Fresh water is limited and most of the supply is derived from wells up to 60 meters deep.

Lembongan Island is a part of a subdistrict of Klungkung regency. Nusa Lembongan is one of three small offshore islands which make up a sub-regency of Klungkung, the others being: Nusa Penida and Nusa Ceningan. Nusa Lembongan is the only one of the three islands within the sub-regency to have any tourist infrastructure and is a popular side destination for visitors to Bali.

The economy is largely tourism-based and Nusa Lembongan is the only one of the three neighbouring islands to have any significant tourism-based infrastructure. There is also subsistence agriculture and fishing on the island and a seaweed farming micro-industry.

The attractions here are mostly natural. The beaches and other coastal landscapes are obviously a key draw, as are the sunsets. There are a limited number of man-made attractions, most notably temples and the rickety suspension bridge.

Activities are very much water-based, with surfing and scuba diving being especially notable.

How to get there ?
The only realistic way to reach Nusa Lembongan from Bali is by boat. There are several options according to budget and speed. Most of the scheduled services leave from Sanur Beach at the end of Jalan Hangtuah, and involve getting your feet wet.

The exact departure and arrival point on this beach depends on the tide. Other services run from Benoa Harbour, and there are local public boat services to and from Padang Bai and Kusamba in East Bali, but these are not recommended for reasons of safety and comfort.
