Amed, as you can see in other post in the guide: "9 days in Bali" it is a relaxing area by the coast perfect for diving and snorkling. For this reason, to get to the differents beaches, and move around this area, the best way it is by bike. Very cheap, just 3.5€/ day but you can rent it even cheaper. Only one problem, the bikes has not got insurance so please!! do not have any accident you will have to pay with your VISA. You can buy petrol in many shops.
