The island has no permanent civilian settlement and entry is controlled by Indonesian authorities; facilities on the island are focused on animal housing and veterinary support.

  • Restricted access: Access is restricted and regulated because the island is used for primate quarantine and breeding work; permission from Indonesian authorities is required to visit.
