Bikes can be hired in most towns and villages, just ask around; the quality varies but there are some reasonable machines out there. If you are staying long term there are several shops in Koh Phangan that stock authentic bikes and they can usually be sold on before you go home. Prices range between Bt100 to Bt150 per day (prices are negotiable on monthly rentals).
Apart from Baan Khai to Thongsala
and on to Haad Yao
, the island is predominantly hilly, thus be prepared for a work out if you cycle elsewhere. Always remember take plenty of water, head wear (helmet advised – the hills give you a lot of speed) and suncream.
There are no official tracks, though that can only be a matter of time, but any nonconcrete road in the hilly areas is a good ride, especially the Thong Nai Pan
and Thaan Sadet roads. Otherwise there are loads of trails to discover, just get those wheels rolling.
