The Silfra Fissure is more than a snorkelling site - it is a surreal passage between two continents! Slip into the clearest water on Earth and watch a hidden world unfold around you. You’re gliding through a cathedral of rocks and shimmering blues, surrounded by volcanic rock walls that drift apart 2cm every year. Few places on the planet let you feel so connected to the forces that shape the Earth. Our expert guides are trained to ensure your safety and confidence in the water, so you’re free to focus on the wonder around you. This is not a typical swim, it’s a once in a lifetime adventure into the heart of Iceland.

An Amazing Experience Made Even Better by Marta (Panda)
The activity was absolutely worth the money and an incredible experience, but what truly brought everything together was our guide, Marta (Panda). She was hilarious, friendly, and did an amazing job explaining everything clearly, so there was never any confusion. She also created such a comfortable and welcoming atmosphere that the entire group quickly felt at ease with one another. Marta really made an already great experience even more memorable. Highly recommend!

Unforgettable experience
We had a great time snorkeling the Silfra fissure! Everyone we came into contact with at Arctic Adventures was friendly and helpful. Our guide Isra was amazing!
He was attentive, knowledgeable, best of all fun! He always made sure we felt comfortable and safe in the water and in our gear.
Thank you Isra for an amazing experience!

An experience unlike any other!
There are likely very few places on Earth that one could see such sights, and Arctic Adventures made it an unforgettable experience! From the start, our guide (shoutout to Iliana!) made sure we were briefed on all the safety elements and properly equipped for the elements. Do keep in mind that moving in the suit and walking some distance holding your fins can be challenging! The earlier time slots had a shorter wait with fewer people in line, but once we were in the water we had the most spectacular views of the fissure and the aquatic environment below. I did bring my own action camera, but the free action shots of you passing through the various checkpoints are great for sharing with your friends! There's just simply nothing like this experience, and I would wholeheartedly recommend it if you are interested!
Operator response
Hi there, glad the experience lived up to "unlike any other." Bringing your own camera and still saying the free shots are great for sharing is the guide knowing the angles that matter.

Yes, You Should snorkel SILFRA!
Do this. Snorkeling in the glacial waters of Silfra is amazing. It is COLD, beautiful, crystal CLEAR water, and for me, a 'once-in-a-lifetime' experience. I don't like being cold, but they provide the warm insulator that goes over light thermals or yoga pants. Recommend a long-sleeved t-shirt (not a turtle-neck or sweater). You can layer up to get there, and easily change. You have a great team of helpers there to get you ready, a safety briefing on where you will go and what to expect. All of it is well orchestrated, so that you spend quality time "face-down" in the water! Absolutely amazing. Easy for nearly anyone, even if you haven't snorkeled before, you can likely do this with the guide. Our guide Maja was awesome. She took great care of our group of 3, plus another 3 (six total). For safety and coordination, the groups are small, and spaced out well, so you won't have other groups overtaking you. The clarity of the water, and seeing the fissure in person is just amazing. They provide a bit of history of the area and where you will go. SNORKEL SILFRA!! If you can do, go do!

Snorkeling with Fernanda was great :)
Fernanda was great and very helpful. She helped if something was wrong and was very joyful. At the end she let us free roam. Can’t recommend her enough :)
Operator response
Hi there, really glad the snorkeling went well. The free roam at the end is Silfra's quiet finale, and it sounds like yours was worth savouring.

Beautiful, peaceful experience
This was an experience that really blew us away. Thank you Fernanda for an awesome snorkel...I was the one who saw the fish!! My wife and I both loved it, such a peaceful glide over a beautiful chasm. Once in the water the bulky claustrophobic suits seemed to melt away and it was as if we were free from all that weight. Highly recommend.
Operator response
Hi Robin, thanks for this. A fish in Silfra is rare enough to be worth mentioning. The weight of the suit vanishing once you're floating is the moment most people realize the experience is nothing like what they imagined. Glad you and your wife loved it.

Operator response
Hi Sam, glad the day went beyond amazing. Support and attention to detail is a guide who's thinking about your experience, not just the route through the fissure.
