As non-swimmers, we were a little nervous about getting in the water, but Andre was super thoughtful and provided us with life jackets so we could still enjoy swimming inside the caves.

8.From Kotor: Boat to Blue Cave & Lady of the Rocks &Submarine Base

★★★★★★★★★★5.0 · 1,104 reviews · 3 hours (approx.) · from $32Top rated

This three-hour English-language speedboat trip from Kotor takes you to the Blue Cave, Our Lady of the Rocks, Perast, former submarine tunnels, and Mamula Fortress. Captains such as Boben may provide commentary, but the amount of guiding can vary. Swimming, sun, spray, and rough water are all part of the deal.

“The trip to the cave takes about one hour to arrive. We found it enjoyable but be aware the water is very choppy from hundreds of boats going in both directions. If you only like smooth sailing this tour is not for you. The cave is amazing but know you probably only spend a few minutes inside as there are so many boats waiting to go through. We ended up swimming a bit away outside the cave which was still enjoyable but only about 10 to 15 minutes before heading back.”

15.From Porto Cristo: East Coast Glass-Bottom Boat Trip

★★★★★★★★★★3.8 · 632 reviews · 1.5 - 5 hours · from $33

From Porto Cristo, choose a 1.5 or 2-hour coastal cruise, or a longer shuttle to Calas de Mallorca. Expect caves, coves, beaches, glass-bottom viewing, and a swim stop when weather allows. The north route visits Cala Bona and Cala Millor, while the south route reaches Cala Varques and the Pirate’s Cave.

“Die Fahrt startete pünktlich und das Personal war freundlich. Es gibt ausreichend Sitzplätze auf 4 Ebenen. Unter Glasboden versteht man etwas anderes, und die Fenster auf der untersten Ebene (unter Wasser) könnten gerne größer sein. Den Kids hat es dennoch großen Spaß gemacht. Besonderes Highlight ist natürlich der Badestop, wo man im offenen Meer schwimmen, tauchen und schnorcheln kann. Man gelangt über eine Leiter, eine Rutsche oder über den direkten Sprung ins Meer. Der Einstieg zurück ins Boot ist auch für weniger geübte leicht möglich. Während der 2,5 ständigen Tour macht das Schiff mehrere Ein-und Ausstiegstopps. Zudem fährt es zweimal in den Eingang einer Höhle, was beeindruckend ist....”
