Easy and unforgettable swim.

I might’ve missed this in their instructions, but highly recommend you arrive wearing heavier socks, a liner for your legs, as well as a tight fitting T-shirt. Space is very very limited to change into the dry suit. The wetsuit keeps you very, very buoyant, so don’t worry about sinking! The water is cold, but totally manageable because the only exposed part of your body are your lips. It was cold and rainy the day of our swim, but that made it actually more special because when your face is under the water, you don’t feel the rain and it’s a peaceful, beautiful, incredible experience. Alex was our guide and he was terrific

Definitely a must !!

So cool! The experience was such a great time, so cool to explore the caves and you can see everything so clearly. We dove with sara, she was helpful and fun, as well as very knowledgeable about local information and the route!! Would go again :)

Fantastic experience!!

It was truly a unique experience! I have wanted to do this for a few years and the experience was amazing. I initially was nervous because I don’t like being cold, but I was absolutely dry and snug in the provided dry suits and “pajamas”. Hanna, our guide, was patient, friendly and genuinely excited…even though she does this every day. It was amazing to see this little sliver of water on the surface and then see this amazing world of blues, greens and browns just dazzle your eyes. Highly recommend!
