Santubong remains one of the best places to spot and watch the Irrawaddy Dolphins (Orcaella Brevirostris) in Southeast Asia. The Irrawaddy Dolphins recently received protection as endangered species under CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora). After dolphins spotting, you have the option to either go for a swim or explore the many river branches in Kuching Wetlands National Park ( the KWNP was designated to be a wetland of international importance under the RAMSAR Convention in 2005).
