1.Porto Vromi: Shipwreck, Caves, & White Beach Swimming Cruise

★★★★★★★★★★4.4 · 1,951 reviews · 3 hours · from $35Our pick

Set out with Porto Vromi Maries Cruises & Fun for a three-hour cruise along Zakynthos’ wild west coast. You’ll photograph Navagio Shipwreck from the boat, enter blue caves, and swim at three clear-water stops, often with skilled captains such as Yannis or Yiannis at the helm. Bring water, sunscreen, and snorkeling gear.

“The tour was better than expected. We chose the pickup option from Zakynthos town that lasted about an hour forty five minutes. The bus driver was super careful and drove slowly to the marine. The captain had amazing energy which made the ride that much better. There were three 30 minutes which was of course the highlight of the trip. 10/10 would recommend for anyone.”

★★★★★★★★★★4.8 · 537 reviews · 9.5 hours · from $106

Spend 9.5 hours aboard the traditional IASON wooden boat from Agia Anna.

The friendly crew, including hosts such as Polina, keeps the day lively, but the boat can feel crowded at full capacity.

“The crew were excellent and the whole trip was a highlight. If I had to pick one though, it would be the Rina cave swim”

From Porto Vromi, you’ll cruise to the Panagiotis shipwreck, peer into coastal blue caves, and stop for swims in clear Ionian water. The shared boat carries up to 60 people, with morning and afternoon departures, onboard toilets, and snorkel equipment. Captains such as Yanniis, Nico, and Costa are praised for handling tight caves and rough seas.

“Tour of the most picturesque part of the island, the one to the northeast.3 stops for swimming, duration of about 3 hours and a half for an absolutely honest price. Captains always engaging and helpful. I feared a little steepness and width of the road to get to Porto Vromi but they turned out to be unfounded fears. Very recommendedAuto-translated”

4.Santorini: Sea Caves Kayak Trip with Snorkeling and Picnic

★★★★★★★★★★5.0 · 311 reviews · 7 hours · from $159

Spend seven active hours with Kalliopi and the Serenity Kayak team along Santorini’s south coast. Paddle past Akrotiri, enter blue-lit sea caves, snorkel by Black Mountain, and cliff jump at White Beach. Pickup, equipment, towels, sun hats, photos, and a homemade local picnic are included. No kayaking experience is needed, but you must swim and handle a full day on the water.

“This was a super unique experience, I would recommend this to anyone who enjoys kayaking. You go up the coast line of Santorini and are able to see angles that you wouldn’t normally get to see. We saw a black, white, and red beach. Taking a kayak into the caves is a one of a kind experience as well. The food prepared was done beautifully and tasted amazing! This is the only snorkeling activity that we were actually able to see fish and sea life. The tour guide does a very good job accommodating everyone in the group, I wouldn’t definitely recommend!”
