Snorkel in between two continents at one of the top diving sites in the planet! Silfra is located in Iceland’s National Park, Thingvellir. It is a fissure that was formed by the divergent tectonic drift of the Eurasian and North American plates.
What makes Silfra exceptionally unique is not only its geological significance, but it is also world-renowned for its crystal clear, fresh glacial water. This is constantly fed with a steady stream of 100m+ visibility drinkable water that creates the unique bio-diversity in this fissure.
We are the only operator in Silfra offering both drysuit and wetsuit together. This means multiple people in your group can book their preferred option.
We include photos as standard so you don't have the hassle of handling your own camera, but you are welcome to bring one! Our guides have all been doing this for years and know the best spots to take pictures of you and your group.

Meet us at Thingvellir National Park, about 50 km from Reykjavik. Once you have met your PADI divemaster certified guide, he or she will be going through the procedure and safety measures of your tour. After, you will put on your gear and head to an exotic underwater canyon/fissure, Silfra, created as the continental plates drift apart at a rate of about 2 cm per year. Silfra is a freshwater fissure where you can see at least 100 meters ahead of you. The water here is so clear and pristine it feels like flying. The approximate time in the water is around 40 minutes. Before leaving you'll have a delicious hot chocolate prepared by your guide for the day. We do have the option to pre-book a wetsuit on another listing. Booking a wetsuit is recommended for people who want to have the chance to dive down or who are scuba divers without the required certifications for the scuba dive. For the wetsuit it is recommended that you are a confident swimmer, if you are not then the drysuit is best for you. To cater to everyone's desires we are the only company that has wetsuits and drysuits allowing them to be in the same group.

Awesome experience for a girls trip. Staff is friendly and ensure safety is important! Shout out to Piotr for saving my friend’s life - she started panicking with the mask on and he saw her right away, grabbed her and helped her calm down and breath properly with the mask on. Highly recommend ! Fun group of operators.

OMG this was a highlight . it was gorgeous and so exciting. The water is cold but you do not feel it in the dry suit. Its not very long but the view underwater is absolutely breathtaking. You should be pretty fit and comfortable in the water. seeing the place where continents separated and the crystal clarity will be with me forever.

The Silfra dry suit snorkeling experience was incredible! Our guide was amazing—super knowledgeable, friendly, and made sure everyone felt comfortable and safe. The water was freezing, but totally worth it for the chance to swim right between the tectonic plates. The visibility was unbelievable, and our guide took lots of great pictures for us to remember it by. Such a unique, once-in-a-lifetime experience

we got to the parking lot and only then noticed thats its a few minutes walk but it was a good warm-up :) we met Dory our guide that helped us get in our gear and explained everything very professionally and calmpy with a big smile. when we got in the water it was cold at first mostly in the face but after 3-4 min, you get used to it and start having fun! the water was so clear that it felt like we were flying! Dori showed us how to dive (none of us could do it) and made sure everyone was comfortable the whole way. we recommend this tour very much! will do it again when we come back to iceland

Incredible!!!! What an amazing adventure!! Was going to use a wetsuit but decided on the dry suit and am happy I did. Yes it’s uncomfortable around your neck as others have commented, but once you’re in the water you quickly forget about any discomfort. It’s also much easier to put on than the wetsuit. And…keeps you toasty warm in the 2 degree water. Face feels super cold at the start but the sensation settles. Our guide Gretar was extremely kind, funny and offered very helpful instructions. You can tell he loves his job and helps you comfortable. My friend and I were in awe of the whole experience. Just brilliant!!
