Plataran L’Harmonie – West Bali National Park is set entirely in the 382 hectares within the West Bali National Park. The park was founded in 1941 to protect the critically endangered Bali Starling. The park is mountainous and consists of a primary monsoon forest, mangrove forest, lowland rain forest, savanna, sea grass vegetation, coral reefs, sandy beaches, and both shallow and deep-sea waters.
The West Bali National Park exhibits a high bio diversity considering its relatively small area. The marine reserve includes the cape shores and several sanctuary islands popular for seabirds in the bay of Gilimanuk on the island of Menjangan.
Wildlife consists mostly of sea and shore birds, the most conspicuous being the Brown Boobies and Lesser Frigate birds. There are several colonies of Terns that nest on a sandy cay at the entrance to Teluk Lumpur (Mud Bay) while the Frigates and Boobies roost on Pulau Burung.
