Whether you are going to take a boat cruise around the Volcano or a view of the Oia sunset from a ship you'll need to get to the Old Port of Fira. You can get down there three ways. The easiest and non-smelly way is to take the cable car; a one way ticket costs 4 euros per person. You may also take a donkey ride down the 5 or 600 steps down. These are rather large steps covered in donkey excrement, yuck, talk about smelly. The last way is to actually walk these steps... If you choose to walk I recommend you use shoes that you plan to throw away. The smell afterwards doesn't ever really leave your shoes. Interestingly I learned that people that work at the shops at the Old Port take the cable car everyday. They get a reduced rate but must purchase a pass for an extended period of time making it not worthwhile for tourists.
