Administratively, the island is 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 island of Nusa Lembongan is just about eight square kilometers in area, and is one of three neighboring islands, the others being the much larger Nusa Penida and the tiny Nusa Ceningan. The three islands are separated from Bali by the Badung Strait. Some visitors may find Nusa Lembongan a little slow after the pace of South Bali.
The Nusa Lembongan Hotel Resort is an excellent place to plan a holiday with the family or just relax and put your feet up with a drink in your hand watching the Sunset over the clear blue ocean. The main activities in Nusa Lembongan include diving, surfing, and snorkeling. The vivid aqua blue water is the cleanest and clearest compared to anywhere else.
