The bay is one of the few places in Indonesia where the rare Banggai cardinalfish has been successfully introduced for conservation observation.
It sits on the migration corridor for various waterbirds, including the Javan Pond Heron and the endangered Bali Myna.
The sediment composition of the bay floor is primarily sandy with high silt content, supporting extensive seagrass meadows.
It is a key site for the long-term monitoring of sea temperature fluctuations in the Bali Strait.
Gilimanuk Bay is a sheltered, U-shaped inlet located on the western tip of Bali, serving as a critical transition zone between the Bali Sea and the Bali Strait. The bay is situated within the protected boundaries of West Bali National Park, known locally as Taman Nasional Bali Barat. Its unique geography creates calm, shallow waters that facilitate the growth of extensive mangrove forests along the coastline. These mangroves act as a significant nursery habitat for local marine species and a feeding ground for migratory birds. The area is positioned directly across from the island of Java, making it a primary maritime gateway for ferry traffic arriving from Ketapang. Beneath the surface, the bay supports a mix of coral reefs and seagrass beds that are monitored for conservation purposes. The environment is notably distinct from the surf-heavy beaches found on Bali's southern coast.
The mangrove boardwalks during low tide for reflections and close-ups of the root systems.

Bring polarized sunglasses to better observe the shallow-water marine life without glare.
Carry identification, as you are entering a protected national park zone.
Do not attempt to swim in the active ferry channel due to strong currents and vessel traffic.
Cover shoulders and knees when passing through local fishing villages; do not touch or walk on the coral reefs.
