Ujung Kulon National Park occupies the southwestern tip of Java in Banten province and protects coastal lowland rainforest, coral reefs and a cluster of offshore islands. It is internationally significant as a refuge for endangered species and for its relatively undisturbed ecosystems.

The park includes beaches, mangrove systems, coral reefs and small islands such as Peucang and Panaitan, which are visited by tourists on regulated trips. It is best known for its role in conserving the Javan rhinoceros and a range of other endemic and rare species.

Ujung Kulon was inscribed as a UNESCO World Heritage Site for its biological values. The area is accessed by boat from small ports on Java and is subject to conservation zoning and visitor restrictions to protect sensitive habitats.

Geographically the park sits at the far western end of Java, facing the Sunda Strait, with a mix of mainland forest and offshore islets.

  • UNESCO and rhinoceros: Designated a UNESCO World Heritage Site in 1991 for its intact lowland tropical rainforest and as the last refuge of the Javan rhinoceros in the wild.

What to See #

  • Peucang Island: A small offshore island popular with visitors for beaches and marine life, used as a base for short excursions and snorkelling.
  • Panaitan Island: A larger island within the park boundary with rugged coastline and limited access, used by wildlife and occasionally visited by guided groups.
  • Ujung Kulon mainland: The contiguous mainland and forested peninsular area that contains lowland rainforest, mangroves and traditional villages at the park edge.

How to Get to Ujung Kulon National Park #
