Alor is the largest island in the Alor archipelago located at the eastern-most end of the Lesser Sunda Islands that runs through southern Indonesia, which from the west include such islands as Bali, Lombok, Sumbawa, Komodo, and Flores.
To the east of the island across the Ombai Strait lie the islands of Wetar and Atauro, the latter belonging to East Timor. To the south, across the Strait of Alor, lies the western part of Timor. To the north lies the Banda Sea. To the west lies Pantar and the other islands of the Alor archipelago, and further yet the rest of the Sunda Islands.
The best snorkelling and diving in Indonesia can be found in the Alor archipelago. Due to intriguing and often very strong currents it is best to snorkel or dive with someone who knows the area well. Transportation to Alor by TransNusa Trigana Air, from Kupang, Denpasar and Surabaya.
Alor Island regency is the least visited and therefore the most unspoiled region of Nusa Tenggara Timur (NTT). Trek to the rim of a volcano on Pantar or dive the straits of Alor and Pantar in a dive destination rated by all to be amongst the best in the world. Ponder on the existence of the Moko drums, which are not found in large numbers anywhere else in Indonesia and can be traced back to the Dongson period in Vietnam around 350 BC and you start to realize that Alor is truly a land lost in time.
Alor diving is known as the best in the world With its smoldering Volcanoes reaching down into crystal clear waters fringed with pristine coral reefs, coconut fringed pure white sandy beaches and traditional villages built half way up mountains, the scenery is as spectacular above as it is below the waterline. Alor Island is so mountainous that it is almost impossible to pass from one side to the other and many of the villages on the island itself can only transport themselves via small wooden ferries. The eight distinct dialects and more than 50 sub-dialects spoken today, testifies to the diversity on Alor.
