Kei Besar is the larger of the main Kei Islands, about 60 km long and dominated by a mountainous spine covered in dense forest. It is far less visited than Kei Kecil and requires more effort to explore — the main villages are on the coast, connected by irregular boat services from Tual, and roads on the island are limited.
The rewards are considerable: traditional stone villages with carved wooden houses, pristine beaches on the eastern coast with no accommodation whatsoever, and the sense of genuine remoteness that the Kei Kecil beaches have started to lose. The western coast villages are the most accessible; the eastern coast requires chartering a boat. Several villages produce traditional Kei woven cloth (tenunan), which makes an excellent purchase. A full day circuit of the accessible western coast by boat is the most practical approach.
