Try beginner scuba in Santorini’s volcanic caldera with patient instructors, reef fish, clear water, equipment, and a 10-person limit.

“This was one of the most anticipated events of our honeymoon for me. I was extremely excited and confident yet when it came time to do it I have to admit I was terrified. Our instructor did a fantastic job at explaining everything and being clear with instructions but for some reason I was still scared when I had everything on and in the water. Luckily he took the time to instill confidence in me by taking baby steps with breathing, slowly descending to practice ear pressure control, and then learning the basics of underwater buoyancy. After doing this I was way more comfortable in just a matter of minutes…”

Paddle Santorini’s cliffs, snorkel in clear water, and enjoy breakfast, GoPro footage, and expert guidance in a private morning adventure.

“This review is only for people coming in on a cruise ship, which is what we did. I wouldn’t do again without a better plan for getting to and from the snorkeling location. It was, logistically speaking, a challenge. About the adventure: Nik and Marcos were great tour guides. The way it works is that you paddle out (with the wind) from a beachfront location to a cove where you snorkel (sorry, the fish are mostly gone but the water is beautiful and crystal clear). Then you get towed back to the beach so you don’t paddle into the wind. My complaint: the booking and the transfer were a hurdle.…”
