Mykonos is a pretty small island, and has beautiful winding roads that lead to small villages and stunning beaches. Personally, renting a car is very expensive and not worth the money. I really don't recommend it for Mykonos. Thus, renting an ATV is a great option and allows you to see much of the island at a pretty cheap price. Make sure that you have your drivers lisence or international drivers license though! This website gives you all of the advice that you need....
