Motorbike hire
Unless you are an experienced dirt bike rider this is not really an advisable form of transport as reaching any of the isolated bays involves going along narrow, twisting, bumpy, severely potholed tracks.
Lederhosenbikes, Ban Mae Hat, T08-1752 8994 (mob), http://www.cycling-koh-tao.com. Rents bikes from ฿200 per day.
Taxi
Taxis and motorbike taxis wait at the end of Mae Hat pier. Sharing taxis makes sense as the cost is per journey, not per person. From Mae Hat to Ao Ta Not costs ฿200-300 with a minimum of 4 in the car. To Sai Ri or Chalok, ฿฿150-200.
