Akvaryum is a secret bay hidden behind the Karaada (Black Island). The only way to go there is to have a daily blue tour, you can also go if you have a boat of course. Although this turquoise paradise is very famous, somehow it has been kept pretty clean so far. The water is so clean and bright that you can see the bottom from 20 meters! Don't forget to have your sea glasses if you visit there! The average prices for such blue tour is around 25-30 euros a day!
