Reviews: Hersonissos: Glass-Bottom Boat Cruise with Swim Stops
Guest User2026-09-22
Unfortunately, I discovered that I get seasick on a boat, but it was still a very fun experience. You depart from the harbor of Chersonissos for a short boat trip of about 2 hours. The first part of the journey takes about half an hour. At the first stop, you get 30 minutes to swim. That's when I suddenly started suffering a lot from seasickness; Maria from the crew was super caring and gave me a seasickness pill. She also gave all kinds of tips. After the first stop, you sail for about 20 minutes to the second stop, where you get 45 minutes to swim. They also throw food into the water so that the fish come, allowing you to see them clearly and swim and snorkel among them. It is a beautiful spot near a small beach, rocks, and a small cave. After that, you are back in the harbor in 10 minutes. The crew was very friendly and caring towards people with seasickness, and there were plenty of swimming accessories available such as snorkels, inflatable rings, and noodles. Definitely recommended for a short trip!

Guest User2026-09-28
This was the most beautiful day out and can't imagine a better way to see Greece ☺️ The pick-up/drop-off logistics was very smooth, the boat was perfect, the food and drinks plentiful delicious, and the crew Christos and Dani were so friendly and helpful. Could not recommend this enough and would book again 👌

Unfortunately, there was too much wind and high waves. Therefore, we could only use a little sail. Some people got seasick. The crew was fantastic, very attentive, and always happy to chat. A great trip. Perhaps not in force 6 winds, but you can't plan for that.
