We boarded the Lindos by Boat boat at Kiotari beach around 9:45 am. We arrived at Lindos within an hour. The trip was very pleasant, very relaxing and the views were great. The cost per person per ticket is 7 euro one way or 14 euros both ways. We were back in Kiotari around 4 pm. Much better option that a coach or a taxi. It gives you enough time to visit acropolis, go shopping and go for a swim. I highly recommend Lindos by Boat.
