Enjoy Silfra snorkeling with a private guide. Silfra Fissure is 2-4 degrees temperature. Choose between a drysuit or a wetsuit for a Viking experience as we spend about 30 - 40 minutes max in the crystal clear water. A wetsuit allows you to to be more flexible and dive under while a drysuit helps keep you warm as you let the light currently slowly take you down the crack between continents.

We booked the 12 o'clock slot and got a small group of three people with our tour guide Ines. The experience takes 3h, of which 30-40 minutes are spent in the water snorkeling between two tectonic plates. After a short introduction and medical questionnaire, you get helped into your dry suit and head to the starting point where you get some quick instructions on how to behave while in the water. The views are breathtaking and you get many photos taken of you. After you get to warm up with a hot drink of choice. This experience is an absolute must do and qas made even better by having our wonderful guide Ines.

An awesome experience with ace tour guide Kaya, who is extremely capable and a lot of fun. We have done a lot of diving, and Silfra is a unique adventure. Highly recommend Adventure Vikings, and Kaya is fantastic.

Dory was a great guide, step by step instructions were perfect and needed for a group of non-snorkelers like us.
