Nusa Lembongan is a small island located southeast of mainland Bali and is part of Klungkung Regency. It belongs to the Nusa Islands group, along with Nusa Ceningan and Nusa Penida. Compared to Bali’s main island, Nusa Lembongan has a more compact geographical layout and a calmer atmosphere.

The island’s landscape consists of coastal plains, clear surrounding waters, and natural shoreline formations. One of the defining environmental features of Nusa Lembongan is the presence of mangrove forests, which play an essential role in protecting the coastline and maintaining marine ecosystems. These natural elements contribute to the island’s ecological importance within the region.

Nusa Lembongan has developed while maintaining its small-island character. Local settlements and infrastructure coexist closely with the natural environment, reflecting a balance between human habitation and nature. This combination of preserved ecosystems and island geography makes Nusa Lembongan a notable example of a small island environment in Bali.
