Diving Center in Elounda is the ONLY organization who offers organized snorkeling trips to the sunken city of Olous for more than 5 years. We made a huge research about the history and the remaining of the city which we will present you with a Power Point presentation at the beginning of the program. Our snorkeling trips are guided by professional snorkel guides who also can teach about different snorkeling technics. There is no better way in exploring the sunken city of Olous!
