Thank you Armand!

This was a wonderful experience. Our tour guide Armand was very helpful and attentive. I had issues acclimating to the water and snorkeling and he helped me every step of the way. Thank you Armand to allowing my husband and I to have the experience of a lifetime!

Super Snorkel

Amazing experience. Anezka was great and very helpful. Hectic check in but after that very well organized. Not as cold as expected.

Unique experience, snorkeling trip between tectonic plates

Beautiful snorkel trip in the rift between the North American plate and the Eurasian plate. Incredibly clear water so you can look far down. The water is 2 degrees C but the thick coat keeps you warm. Putting on the suit takes quite a while. Very friendly and helpful guide. My suit was a little too big, that's the only downside, because of that air collects around your feet and your fins stay less easily underwater. The guide also took underwater photos that became available online for free.
