Kos Boat Tours: Our 6 Best

1.From the Port of Kos: Full Day Boat Cruise to 3 Islands

★★★★★★★★★★4.8 · 5,137 reviews · 7h 30m · from $35Our pick

Sail from Kos on the Odyssey for a full day around Kalymnos, Plati, and Pserimos. You’ll see Vathi’s fjord, swim from the boat, watch for dolphins near fish farms, and eat souvlaki or a vegetarian lunch. The English-speaking crew, led by Captain Yanas, keeps the pace easy rather than turning the trip into a loud party cruise.

“The overall experience, as I mentioned, is good and satisfying. My only comment relates to the music: I would have preferred old Greek music, which would have complemented the Greek Mediterranean experience.”

“It was my birthday and I was travelling solo. The staffs onboard were too kind. Flod was good. it's great value for money. I came from Bodrum to Kos via boat and thankfully they waited for me as customs was taking a very long time. I am certain that I am coming back with friends to show them the hospitality of Greece. I had the chance to jump off the boat i assume it was 10m tall and they had the inflatable slides. my oh my that was really fun”

3.Full Day 3-Island Boat Cruise from Port of Kos

★★★★★★★★★★5.0 · 1,133 reviews · 7 hours 15 minutes (approx.) · from $36Top rated

Spend about seven hours aboard Odyssey Boat Cruise from Kos, visiting Vathi on Kalymnos and Pserimos, with a swim near Plati. Expect dolphin watching, a Greek barbecue lunch, music, a bar, and one hour ashore at each island. Captain Giannis and the crew keep the day moving.

“Long day but beautiful views, the island stops were fabulous, particularly the two that you leave the boat to visit. Seeing dolphins was an added bonus. The seating was a little uncomfortable for the number of hours you are on the boat. Crew friendly and helpful. The swimming experience is not necessarily ideal for all due to the options of jumping off the side of the boat from quite a height or a vertical descent by ladder, I wasn’t confident enough to try either sadly. All in all, a good trip and would recommend as long as aware of the practicalities. Value for money.”

5.3-Island Cruise with Lunch, Swimming and Audio Guide

★★★★★★★★★★4.6 · 341 reviews · 7h 30m · from $29

Spend about seven and a half hours aboard the wooden Santa Maria, cruising from Kos to Kalymnos, Platy, and Pserimos. You get swimming stops, a Greek barbecue lunch, dolphin watching, and a free phone audio guide in several languages. Guides such as Alex and Alexander add humor, music, and local detail.

“A fun day was had! We first stopped in Kalymnos and ate souvlaki at a little restaurant by the port, then some swimming and jumping from a small cliff. Plati was a swimming stop only, but the water is amazing and jumping from the upper deck of a boat is always fun. Last stop Pserimos, where there was a beach, some cafes, and vendors to buy from. I advise arriving at the ship early if you want to sit in the shade. Our hosts were very friendly and made sure the energy on the boat was kept up. Enjoyable in all regards.”
