156 tours  ·  from $18 a head

A cave you can only reach by water is a different booking: the hull, the group size and the sea state matter more than the guide. These 15 compare what actually gets inside, how long it waits there and what a seat costs.

Blue Cave Small-Group Boat Tour from Dubrovnik

2.Blue Cave Small-Group Boat Tour from Dubrovnik

★★★★★★★★★★5.0 · 9,360 reviews · 4 hours (approx.) · from $84Top rated

Spend about four hours on a boat from Dubrovnik, visiting the Blue Cave, Koločep’s three sea caves, and sandy Sunj Beach on Lopud. You swim into the caves rather than taking the boat inside. Groups are capped at 12, with snorkeling gear and one drink at each stop. Captains such as Anthony, James, Dominic, Roko, and Tino are known for friendly, attentive service.

“The driver picks up close to the port, The blue water is beautiful. But the boat doesn’t go into the caves. You swim into the caves that are pretty dark. I was disappointed with that. Our boat captain was super nice. Dominic is his name. I think overall it was nice but I really wanted to see bigger caves where you could actually see good. The beach at the end of tour was ok. Pretty small w places to eat & drink. The snorkeling equipment was shared and not sanitized. We didn’t use that.”

Join Captain Kevin and the Hornblower crew for a seven-hour family-run cruise from St. Paul’s Bay.

“It was so much fun and a great way to see Gozo/Blue Lagoon. We didn’t get to swim in the crystal lagoon but this may have been due to time of year (April). However we stopped at the best location in the Blue Lagoon and slid, jumped and swam in those gorgeous waters! It was so much fun. Communication was clear and we enjoyed the free time we had in Gozo. I would recommend if you’re strapped for time and don’t want to navigate the transport systems!”

They were also clear on their instructions for departure when we stopped for swimming and into town. There was food provided on board that was reasonably priced, if you are getting a drink I enjoyed the Corfu spritz. I would recommend getting on the boat early to secure a good spot because even in the off season the boat was very full. The stop in Gaios was a good amount of time, if you are eating I suggest doing that first as the restaurants get…”

Guides such as Maria, Tomas, Rui, and Rafael have led recent trips, though crew assignments vary.

“Solo traveller. This tour was absolutely fantastic. I went for the 12:30 appointment in the second week of October and the dolphins were still there. We were able to see common dolphins and bottle nose dolphins! Our skipper (Diogo) and our marine biologist (Rui) were absolutely fantastic! They allowed us to see everything and the weather was great. I would recommend bringing a light jacket or something with you as you are whipping over the sea at great speed so it does get a bit cold. The Seacret team were great and check in was really easy. I’d highly recommend going on this tour! It’s well worth the money! 10/10”

“This boat tour was PER-FECT ! I wouldn’t change a thing. We departed from Benitses Port, it was approximately 1h30 to Paxos. When we arrived to Lakkas, we had time (2h) to enjoy the beach before all the other boats arrived, and time to explore the city a little bit. Then we went on the boat again to the blue caves (we saw 2!), and then went to Antipaxos for a beautiful swim in the clear waters. During all the time on the boat, we had the chance of having a guide that talked greek/ english/german/ italian! It was super nice. Truly an amazing tour that anyone visiting Corfu should…”
