I wasn't sure what to expect. But the snorkel guide... im sorry I forgot his name but he was from Turkey... was excellent. He explained things carefully and clearly. As a scuba diver I was a bit disappointed my timing meant I couldn't dive because I was flying out that day and honestly? It was so beautiful I cried in the water. My guide said the diving aspect didn't add much more, just weight... and I think he was right. 10/10. My only regret was i didnt have cash for a tip. The sky lagoon visit was the perfect compliment. It was a fantastic experience and the location was completely flexible for an earlier time to come in.

A brilliant two part experience. Thanks to Ignis our snorkelling guide, and looked after us brilliantly. A unique experience, with stunningly clear water, and other than some cold hands we stayed warm and dry. Finishing the day with a beautiful evening at the Sky Lagoon

This was such a great experience. First, our guide, Ines, was absolutely wonderful! They provide a wetsuit, drysuit, gloves, hat….and she worked to ensure each piece was on and fitted to ensure we did not get wet during this experience. She was patient and very friendly! The sky lagoon was absolutely wonderful! Felt like a luxury spa going thru the 7 steps and we loved the view…..just beautiful!!

This was a wonderful experience. I thought I would freeze but I wore warm clothes (snug fitting 2 layers) under the wet and dry suits and felt fine other than my face being cold. Ines was an excellent guide. She explained things well and made it fun!

I have a blast. I recommand the combo. It's way less expensive. Sulfra is a must. I'm glad to choose Adventure Vikings. It's a smaller company, but the size of the groups is also smaller. It means that we have more space to swim and that we can have more personnal interactions with our guide. Ines is a bubbly guide. She makes sure everyone feels comfortable and swim safely. Very funny. I recommand her. After feeling cold. You have to experience the Sky Lagoon and to feel hot. Very beautiful spa and love the nordic icelandic ritual.
