“This boat tour was PER-FECT ! I wouldn’t change a thing. We departed from Benitses Port, it was approximately 1h30 to Paxos. When we arrived to Lakkas, we had time (2h) to enjoy the beach before all the other boats arrived, and time to explore the city a little bit. Then we went on the boat again to the blue caves (we saw 2!), and then went to Antipaxos for a beautiful swim in the clear waters. During all the time on the boat, we had the chance of having a guide that talked greek/ english/german/ italian! It was super nice. Truly an amazing tour that anyone visiting Corfu should…”
