The Tanimbar Islands, southwest of the Keis, have a distinct culture most similar to that found in Southwest Maluku and East Nusa Tenggara.
They remain a major centre for the production of traditional crafts like ikat cloth and carved wooden statues in Maluku, and also have their own forms of music and dance, though as usual, you will have to be lucky (or pay up) to experience these first hand. Cultural attractions apart, the Tanimbars also have their own distinct fauna, including 8 species of birds endemic to the archipelago, and the usual fine beaches.
Most of the above attractions can be found on the main island of Yamdena, which is also home to the regional capital Saumlaki. This is the most accessible of the islands, and the main focus of most visits. Of the other islands, Larat in the north, with its town of the same name is the most accessible one, and the only one to offer any facilities.
