Explore East Nusa Tenggara

In the Lesser Sunda Islands lies East Nusa Tenggara, which consists of more than 500 islands stretching from Komodo all the way to West Timor. The islands of Flores to Alor are volcanic, creating excellent conditions for species rich marine ecosystems while Sumba, Savu, Roti and West Timor are uplifted coral limestone. This makes East Nusa Tenggara diving intoxicating as you are thrilled with the prospect of discovering rare marine life and dive sites with diverse topography.

In Flores, you can drift in challenging currents among manta rays at pinnacles, walls and deep drop-offs or head to Maumere in search of an endless list of macro life. Alor and its surrounding islands, Lembata and Pantar, offer negative entries onto seamounts while the option of diving calm coral reefs is always available. The Savu Islands are declared a marine park, providing the chance to dive with whales, dolphins, dugongs while Rote is an untouched frontier with only one dive resort to choose from. Diving in West Timor, will find you in muck dives searching for mandarin fish and sea moths or shadowed by towering walls spotting reef sharks.

While scuba diving in East Nusa Tenggara you’ll find many areas have limited dive resorts and dive centres. Yet Labuan Bajo, the gateway to Komodo National Park has many and dive courses are a popular option. To experience East Nusa Tenggara diving to the full, liveaboards run year-round visiting dive sites unknown to daily trip boats.
