Nice folk and nice area to visit. No pressure to do anything.. you can lie on the boat for the 4 hours if your prefer. FYI to people thinking of doing it.. if one of your group struggles with swimming or breathing through your mouth, mention it when booking it as there is 'aids' that you can get.

Exceptional experience! Highly recommended! Very professional guide. The coolest thing was we saw an octopus which changed a brilliant raspberry color right below us. So fascinating. We also saw cuddle fish, star fish, sponges, sea anemones, varied colored fish, pottery to name some. I wouldn't have seen stuff without him because he knew how to spot stuff. His equipment is in excellent condition. You get a wet suit cause it can get chilly being in the water so long. It is an easy ride from central Athens on the Ktel bus which I took which was an experience in and of itself. The water was crystal clear and even in mid October the weather was perfect (even hot out of the water). The coast is pristine clean and peacefully quiet and quaint. So different from Athens which is teaming with crowds of tourists. Just such a terrific trip and I also was traveling solo. Dmitris even picked me up from the bus stop and drove me back to the bus stop.

Very interesting tour, great instructor

Even though we couldn’t go by boat because of the strong wind, the instructor took us to a great spot along the shore where we saw several underwater creatures like sea cucumbers and starfish, among others. We were provided with snacks, water and juice. Unfortunately, we did not have enough cash with us to tip the instructor, as he definitely had earned it. Highly recommend!
