Sunda Strait

The Sunda Strait lies between the Indonesian islands of Java and Sumatra and connects the Java Sea to the Indian Ocean with one of the world’s most famous active volcanoes, Krakatoa. The archipelago of Krakatoa is a small group of volcanic islands that form part of the Ujung Kulon National Park. A UNESCO world heritage site, its landscape is the largest remaining lowland rainforest in Java. It is the last known refuge for the endangered Javan rhinoceros and protected home to many rare plant species, reptiles, birds and mammals including banteng, silvery gibbon, crab-eating macaque, Javan leopard, Sumatran dhole, mouse deer, Javan rusa and smooth-coated otter. While diving any of the four islands of Krakatau are great spots for deep wall exploring a plethora of coral reefs.

The newly opened Tambaling Wildlife Sanctuary on the southern tip of Sumatra provides a very good attraction for superyachts. Situated in a natural harbour protected from the wild seas outside, it is accessible only by air or by yacht. Guests can fly into the area by jet or straight from the yacht to explore the wildlife sanctuary and rehabilitation center for the Sumatra Tigers. Since its opening the foundation which heads the restoration programs and recovery processes of the land has implemented efforts which has seen the reforestation and return of endangered species including sea turtles and the Sunda pangolin, to their natural habitats.

South Lumpung on the Sumatran side is known for its great bay muck diving and ‘beautifully challenging’ drift diving. Strong currents which run from the strait feed nutrients to the coral reefs and attract large pelagics and marine mammals. West of the strait divers are spoiled by the scenic view of well-preserved coral reefs, pinnacles and deep walls. Over time, volcanic stones have created mounds underwater and created a  species.magical seascape of coral and fish.
