    What our customers are saying about us

    • Brittany Clark

      From the mini bus transfer with Bus Leader, picking us up at the local bus stop from our hotel, the scenic drive to the Port of Athinios, the gorgeous Aphrodite sailing ship, the crew and their diligence in looking after all the passengers, their knowledge and skills in giving you the information when participating in the walk to the volcano and the swim in the thermal waters, the Greek dinner on board, finishing up with the traditional Zorba dance and the stunning views of the sunset over Oia. Recommended this particular trip to other guests staying at our hotel, Olympia, in Perivolos. Cannot recommend this trip highly enough. Fantastic experience and the highlight of our trip for mum and I.

    • David Doe

      This entire experience was absolutely fabulous! The boat, Ulysses, our guide was funny,
      energetic and knowledgeable. The hot springs, volcano , dinner and sunset were great.
      Perfect way to see and experience the caldera!!

    • Frances Hill

      Spectacular scenery, from the volcano, to the crater, to the sheer cliffs and views from
      below. Guide was great! We especially enjoyed when the sails were unfurled for the sunset
      viewing at the end and of course a Greek dance for all at the end!

    • Jennth Norz

      This was the BEST tour I have ever been on! The tour guide was amazing, knew so much about the history of the Island and surrounding areas and the whole thing was so much fun! The weather was unfortunate for us meaning we had to bring raincoats and jumpers, but when the sun set it was magical. The dinner was also plentiful and yummy! Worth every penny. Please do this!!
