I am Santorini, is the way to see the Island - If you are looking for a guide to help you immerse yourself in Santorini culture and beauty, then Markos is your person. We had a wonderful morning of Markos showing us what Santorini truly is. Markos was flexible, fun and this wealth of local knowledge was invaluable. He showed us places we would never have known to look for and the tour was relaxing and fun. He also set us up for an afternoon cruise with a small group that included multiple swim stops and a meal that was one of the best meals we had in Greece. Highly recommend. Thanks you, so much Markos

Highly recommended! - A tour with Markos is highly recommended! The Caldera Sunset Tour is breathtaking. Markos is an entertaining host with deep knowledge around the island. On top, he recommended some local places on the island. We really enjoyed our time and would definitely go again!

Private sunset sail boat tour - What a fabulous way to see the island and experience the sunset. The four of us were extremely well looked after with plentifully, drinks and food with a deliciously diner freshly made on Board. Swimming was fab in the beautiful clear waters as was being able to view a lot of the island’s massive variety of cliffs and rock formations and colours you just don’t see on Land. Markos was a great communicator and made the whole booking experience extremely easy. He was very good to also give us some great local recommendations which we enjoyed and tips for visiting certain parts of the island. Thanks for the memories

Relaxing day under the Grecian sun - We had a great time on our caldera tour. Unfortunately, it sounded like the boat we were supposed to be on was destroyed in a storm 10 days before we arrived, but Markos made the transition to another boat completely seamless and we kept the planned itinerary around the caldera. Pick-up was convenient and on time, and drop-off was flexible. It was such a relaxing day and my boyfriend’s favorite part of our trip to Greece!

Not Just A Tour Guide - We have done a Sunset Cruise of the Caldera on a previous visit to Santorini (2013), but this was exceptional! Everything just made us feel very relaxed and at home. Markos was the perfect host, nothing was too much trouble. Not only is Markos very knowledgeable, but he is also very entertaining. On top of this he is genuinely interested in the people on his tours. Not just a tour guide but a friend as well. So glad we decided to repeat this trip and will definitely use I Am Santorini again. Highly recommend them.

A Unique Experience! - Group of 4 of us. We stopped at a couple of places to go swimming and then watched the sunset. The food was great, communication before the boat was easy and overall lovely experience, highly recommend. Markos was a great host!

Amazing!!! - Thanks again Markos! Perfect day on a private sailing yacht with great food and the best skipper you can get! Fully recommended

Thank you Markos - Absolutely amazing time! Probably the most memorable moment of our trip to Santorini. Great sources of information about the caldera from Markos. The water was a bit chilly this time of year, so we waited for the “hot springs” portion of swimming, which aren’t actually separate springs, but vents beneath the sea. The water is warmer in spots but it moves. So you’ll get hit with a jet of warm water for a bit and then regular sea water temp, and back and forth. Overall, fantastic experience and would highly recommend it! So worth it.

Great experience - Great trip, Markos was amazing! He has a variety of trips to make the tourists feel welcome and understand the Greek hospitality.

Rude captain, shortened excursion, small boat - Captain was rude, inspiring this negative review. Excursion did not stop to visit all areas promised on itinerary. Food was bland. Boat was smaller than anticipated, so no sense of privacy despite small group.
