Afternoon exploring the sea with Costas was an amazing experience. He showed us interesting sites and was a lovely host. He was also flexible when the weather looked bad which was much appreciated.

Very nice excursion with Costas. Very attentive and adapts to your wishes. We understand the island of Santorini and its history from inside the crater, it is beautiful and very informative To do

We loved our 5-hour cruise with the lovely and informative Costas! His boat is fantastic and he took us to some of the most beautiful, isolated, and tranquil spots around Santorini and its neighbouring islands, as well as to the more popular beaches such as the White and Red beaches. The tour is flexible and Costas was very willing to adapt the stops to our interests. Costas also provided drinks, snacks, towels, and snorkeling gear so we were able to just sit back and relax. This is certainly the best way to see Santorini! Highly recommended - this was a real highlight of our trip.

This private boat tour really exceeded our expectations and Mr. Costas (the captain) was the coolest Greek guy we have ever met. We have done many times private cruise on this island (both with Catamaran & motor boat). I have to say that this specific one was the best so far. You can reach any distance in little amount of time, you can also reach spots for privacy and you can go near beaches & rocks that no other boat can go there. Really amazing trip totally recommend it!

Had an awesome time with Costas! He made us a customized tour catering for what each of the family members likes; and he knew lots about the islands, area and really cool places to stop for a swim, snorkel, jumping off rocks etc. In fact we had such a good day - we did another day with him a few days later to another island! He is super cool 😎 and highly recommended!

The boat tour with Costas was great from the beginning, the pick up at the port in Thira was as agreed and the tour was excellent! We would recommend the tour to anyone who wants to admire Santorini from the water.

My son and I had an incredible spearfishing experience! Costas could be a better guide—and person. Both of us are avid swimmers but novices when it came to spearfishing and freediving, so we were unsure of our success. Costas quickly and confidently provided us with training and techniques to help us feel confident at depth and on the hunt. He is a true enthusiast, and his passion for the purity of the sport immediately rubbed off on us. By the end of the day, after harvesting several fish, he suggested we bring our catch to a local restaurant to be prepared the next day(which he arranged). The lunch—featuring our fish prepared in five different ways, from ceviche to fried and grilled—was the best meal of our 14 days in Greece (and I’m a big fan of Greek cuisine). Throughout the entire experience, communication and execution were flawless. If you're considering an on-water adventure, look no further, Costas and Archipelago Cruises is the right choice. Thanks again for making the highlight of our trip.

This boat trip was the highlight of our Santorini trip! The combination of fascinating information about the island's history and geology, and the breathtaking swim and snorkel spots made for an unforgettable day. Costas was an amazing host and captain! Our three children were captivated by both the fun of the boat ride and the incredible places we stopped to swim and snorkel. The whole family had a blast jumping into the water and exploring the underwater world. This is a must-do experience for anyone visiting Santorini, and we highly recommend it for families.

Captain Costas put us on the fish!! He made coordinating the trip from across the pond a breeze. He provided all the training and gear needed for a successful trip. As a first time spearo, his guidance proved invaluable. He even went out of his way to coordinate with a local restaurant to cook the multiple fish I shot. Costas is the only guy I'd trust to spearfish with in Santorini. Thanks again!!
