The Silfra Fissure is one of Icelandic nature’s most phenomenal creations. It’s the only place in the world where you can dive and snorkel between two tectonic plates. Located between the North American and Eurasian continental plates, the crack slowly expands every year, as the plates shift farther away from each other.
One of the reasons Silfra is so popular among divers is its great underwater visibility. The rift is filled with crystal clear meltwater from Langjökull, the second largest glacier in Europe. The water travels slowly through fields of porous lava rocks that filter the water. It’s crisp and fresh, and totally safe to drink! Diving in such pure water creates an exceptional diving experience.
Marine life in Silfra is quite sparse because of the low water temperatures (around 36°F or 2°C). However, the cold doesn’t bother the green algae that thrive on the rocks in the rift. Prepare for an out-of-this-world subaquatic chasm of sublime colors and mystical rock formations!

Once you arrive at Silfra, our experienced dive guides will give a thorough briefing. This will include details about diving procedures, signs and signals, national park rules, equipment, the route, and, most importantly, how to use the dry suit.
We’ll gear you up and walk you to the entrance of the dive site. You’ll have to walk a few hundred meters in your dry suit before getting to the water. You’ll first stand on a platform with water up to your waist so you can comfortably get used to the frigid water temperature. After each diver has done a weight check with the dive guide, it will be time to plunge into the rift!
You’ll dive through each of the four sections of Silfra. The first section is the Silfra Deep Crack, which is long and narrow as it winds to the left and right. As we dive further, the fissure widens into what we call the Silfra Hall. It leads to the fissures deepest point called the Silfra Cathedral. The maximum depth allowed for a dive at Silfra is 18 meters, but the visibility is far deeper than that. After the Cathedral, we’ll turn left entering the final part of the dive, Silfra Lagoon.
After stepping onto the exit platform, your guide will help you remove your fins and you’ll have a chance to get the blood flowing with the roughly a 1300-feet (400-meter) walk back to the car park.
Once back in the car park, we’ll help you take the rest of your gear off and get you some hot chocolate and cookies. Warm your hands while telling us about your dive!
You have an option of doing two dives in the summer (around 30 minutes each), but in the winter if the temperature is below freezing, we will only do one longer dive for safety reasons.
Important! For our diving tours in Silfra, you are required to have a dry suit certification or a log book with 10 logged dry suit dives in the last two years. However, if you don’t have any of these, you can join our 2-day dry suit specialty course that includes PADI Dry Suit Specialty course on day one and diving in Silfra on the second day. Otherwise, check out our snorkeling tour in Silfra, which doesn’t require any certification or experience!
We offer free pickups from Reykjavik on all dive tours. If you plan to meet us on location, the meeting point is at the Silfra car park, in Thingvellir National Park. Please note that the National park charges a small parking fee for those that ch...)

Silfra fissure dives
Reviewed on November 01, 2018 by Ian Lundy-Lester From our post-trip system
I was picked up as agreed from my Reykjavík hotel, and the scenic drive to the dive site was amazing. My tour/dive-guide was Zsolti and he gave us lots of interesting facts on the way to the site. The dive kit fitted perfectly (so please fill in any pre-trip questionnaire in full - it will really help you enjoy your time at the dive site) - and I was lucky enough to get a brand new crushed neoprene suit. I dived in late October 2018 and the air temperature was -3'C when kitting up (and wind-chill on top), but Arctic Adventures had a "Changing Room" van to get changed in where I could easily stand up (I'm 6' / 1.83m). The water temperature in the fissure was +3'C, so it was much better to be in the water quickly to get out of the wind. Zsolti, and his colleague Tamsen, were extremely helpful, personable and funny when I was getting kitted up, and even put my dive mask on for me. 5 star service throughout. I had the option to have two dives in Silfra, and after the first one I couldn't wait to get in again. The water was VERY clear and I had a bit of mild vertigo when looking down from the platform to start with. Zsolti was a very calm and attentive dive leader and I felt very safe due to the level of experience he was clearly demonstrating. Don't think about it... get booked up and go diving in the Silfra fissure.

Awesome dive! Friendly, fun, knowledgable and experienced guides. Fabulous diving experience. Small groups in the water make the experience even better as you feel like you have the place to yourself. Just the most unforgettable and wonderful experience. Thank you so much
Still got questions about the tour? Hopefully you will find the answer here.
Yes, you need to have previous experience in dry suit diving. To dive in Silfra you need to have a special Dry Suit Certification or a logbook showing that you’ve completed at least 10 dry suit dives, one of them being in the last two years. Your guide will ask you to present your documents before the tour starts. Please note that without the required documents, you will not be allowed to dive.
If you aren’t dry suit certified but have an Open Water Diver Certification, we also offer a PADI Dry Suit Specialty Course.
If you’re certified with PADI but don’t have your certification card, please contact us well in advance and we’ll check if we can find you in the PADI online database. If you show up to the tour start without your certification card or without contacting us in advance — we will not allow you to participate in the diving tour.
We provide you with an undersuit, a dry suit, and all the additional equipment required to dive in Silfra: including cold water regulators, a BCD (buoyancy control device), a weight harness, and tanks. You’ll also be given a mask, fins, a hood, and gloves.
We use high-quality neoprene dry suits from Waterproof and O´Three manufacturers.
Absolutely. Just make sure it’s waterproof if you want to take your camera underwater.
The maximum depth of dive is 59 ft (18 m). However, most of the dive is spent at a shallower depth due to the topography of the site.
Each Silfra dive is approximately 30 minutes.
Yes, complimentary pick-up and drop-off from Reykjavik is included on all of our diving tours.
You can dive in the Silfra Fissure year-round, though it’s a little bit colder in the winter due to the frigid outside temperatures
