Join this wetsuit snorkelling tour in Silfra fissure at the UNESCO World Heritage Site, Thingvellir National Park. It's an out of this world adventure inside a hidden natural wonder, where the 100 m (almost 330 ft) underwater visibility and bright colours make for an unbelievable afternoon.

The pristine water in Silfra is one of the purest and clearest streams you’ll find on the planet, which is why it is named Silfra (silver)! When snorkelling in Silfra, you are travelling between two continents, ending the tour in a lagoon often called "the real Blue Lagoon" because of the bright blue colour of the water.

Silfra is one of the most highly regarded diving locations on earth for all these reasons and more. Located on the Mid-Atlantic Ridge, it is one of the largest fissures on Lake Þingvallavatn, a result of the endless tension of the earth as pressure builds and earthquakes tear the landscape, widening into fissures and underwater caves.

Snorkelling in Silfra rift where you are guided into this magnificent scenery is a treat for all nature lovers and adventure seeking individuals and groups.

Because it is a wetsuit tour, you'll have more freedom of movement and will even be able to free dive by holding your breath. The wetsuits you will use are 6 mm in thickness and isolate the body well from the cold water.

The water temperature is between 2–4 °C (36–39 °F). However, when wearing a wetsuit, water always gets underneath the suit, which slowly warms up. You'll need to bring a bathing suit to wear underneath the wetsuit.

In short, you'll be able to dive deeper, but you'll be exposed to colder temperatures. If you think the water might be too cold for you, try Adventure Viking's drysuit tour, which provides the same beautiful scenery while keeping you much warmer.

So don't miss your chance to see the beautiful underwater world of Silfra fissure! Check availability by choosing a date.

Absolutely amazing dive! The dive crew were consummate professionals and took the right time and care to ensure that everyone had a safe and enjoyable trip.

The staff were friendly and informative. The snorkel tour was amazing and the water was so clear! I would definitely do this if you're visiting Iceland!

Beautiful experience. The guides were informative but worked quickly. The process of suiting up is a little uncomfortable but so worth it once you start to snorkel.

This was the highlight of my trip to iceland! The staff were the nicest and even though we got a little messed up with the pick up they personally took me there and I had the experience of my life! Definitely do a wet suit! I thought it would be colder but it is actually pretty good, you have so much freedom to move in the water! Adventure Vikings is the nest company to do this tour with!

I booked this on a whim the night before... the most incredible thing I've ever seen! The guides were super helpful and friendly and even gave me hints for the rest of the golden circle drive. I would HIGHLY recommend this snorkeling tour. (Go for the wetsuit!!)

Absolutely unreal! Totally amazing . Adventure Viking is the best company to do your snorkeling trip with in Iceland. It was not as cold as I expected and the views where absolutely stunning. Five stars and I would do this again. The Instructors were absolutely incredible, and had so much knowledge. I felt extremely safe with them.

Definitely do the wet suit option if you can bear the cold a bit. Instructors were great and very easy to talk with, only criticism is that due to others in group wearing dry suits they were finishing way too early as they were only able to float round an not dive. I would have preferred more time in water, even though it was only 2°. Both myself and partner have memories for life. Thanks team x

Absolutely unreal! Went in a wetsuit at 9am and was cold but it was worth every second. Diving down to get better shots for 30 minutes made it all the better!

I did this in January and was nervous about the cold, but it was well worth it! Everyone in a drysuit was jealous of how freely I could move and swim. This was an awesome experience and would tell anyone I know to do it! The guides were very helpful and super friendly.

I was a bit scared of how cold I would be in a wetsuit in November, and it was COLD, but the ability to dive down below the water and the view you get when looking up more than makes up for it. The guides were very nice and helpful. They made sure that everyone was comfortable with what they were doing (and helped get me out of the wetsuit as quickly as possible and into a jacket). And the satisfaction of diving in 2* water in a wetsuit makes for a great story! It was a wonderful experience.

Snorkelling in the Silfra fissure was definitely one of the highlights in Iceland! I did the tour in a wetsuit and would recommend it! It is cold but not too cold. The guides were nice and helpful! Do it! :)

Fun and beautiful but like the others said, very cold :) Would not want to have missed it though. Looking down between the two continents was amazing. Highly recommended.

One of a kind experience! Wasn't quite as cold as I thought it would be, and I wore a wetsuit. Well worth it!


this tour was fantastic, amazing views... but is cold, very cold... i recommend the dry suit! hehehe

Snorkelling was great…views are amazing and wearing a drysuit was interesting. We did it on probably the coldest day of our trip but it was worth it. Would definitely recommend this activity. The guides were both really friendly and helpful. Thank you.

This was by far the best and coolest thing my sister and I did while in iceland. Even now I tell all my friends about how I got to go snorkelling in Iceland. The tour was incredibly fun and it was one of the most beautiful things I've ever seen. Not to mention our guide was great too! He was very informative and gave us plenty of time to explore. Even after the swim he gave my sister and I tips on where else to go along the Golden Circle. He was super friendly and made the tour an unforgettable experience. Overall this was one of the best travel experiences I've ever had and this specific tour was amazing! I 100% would recommend this tour group!

It was extremely cold, but our guide was great and did her very best to keep us cheerful! She went above and beyond helping us get in and out of our wetsuits :/ A beautiful and unique experience if you can handle the temperature!

The snorkeling experience itself was amazing. Very cool experience. The guide was not very talkative nor informative. He didn't tell us anything about the silfa fissure, just helped us get dressed and took us to water. He did not provide any information about silfra. I had to go online afterward and read up on it myself. Also, HUGE TIP, it way too cold to get dressed in suites outdoors in the winter time. It is below 0 outside, and the suites and gloves provided to us had ice inside on top of that. It is not pleasant to loose sentation of your hands and feet before even getting in the cold water. You should really have an indoor changing room besides the small bathroom stall. Had we the ability to change into our suites in a nice warm space, it would have made the experience a lot more enjoyable overall.
