You will experience a truly breath-taking experience, as you drift peacefully through the electric blue waters of the Silfra Fissure. The water is astoundingly clear, because it is glacial water from the Langjökull Glacier, meaning that the temperature is about 2-4 degrees. But don’t worry, we provide fully insulated dry-suits and there will be a certified expert with you at all times. The water in Silfra is as pure as water can get: meaning that you can drink it at any time during the dive!

Silfra is actually a rift in the Earth between two tectonic plates. Swim in the gap between Europe and North America in crystal-clear water.

Snorkeling Silfra Fissure Near The Rocks In Iceland

Silfra is also the only place in the world, where you can swim between two continents: those of North America and Europe, which are actually drifting apart (at a rate of 2cm a year)! This combined with the incredible visibility makes Silfra and experience that you won’t want to miss! Our ‘into the blue tour’ offers you the chance to take a journey into an alien world: both beautiful and captivating. Silfra is actually a rift in the Earth between two tectonic plates. Swim in the gap between Europe and North America in crystal-clear water.

We try to offer everybody who snorkels in Silfra the chance to have their photo taken, whilst experiencing the wonders of Silfra (and most people take us up on the offer, in such a stunning and unique setting). You can buy the photos at the end of the tour for 3900 ISK, using either cards or cash. Just make sure to let your friendly guide know once you get there (before you walk to Silfra). Kindly note that we cannot guarantee that your photo can be taken.

Snorkeling Silfra Near The Rocks In Iceland

Silfra is located in the heart of the historic Thingvellir National Park, a UNESCO World Heritage Site. The fissure opened after a strong earthquake in 1789. The North American and Eurasian tectonic plates continue to move apart farther apart at a rate of about 0.79 in (2 cm) every year.

To get to Silfra for your snorkeling trip, you can choose to be picked up from your selected location in Reykjavik. You may also choose to meet us on-location at Thingvellir, where our friendly guides will be waiting for you.

The best part is that you don’t need any certification or previous snorkeling experience. The only requirements are that you’re healthy, adventurous, and able to swim!

Once you’re at Silfra, you’ll be given all the necessary equipment and put on your drysuit. You’ll swim in the “lazy current,” a stream of glacial water that flows slowly in the fissure. The pure glacial water filling the rift has been filtered by lava rock for decades, so feel free to take a sip while you’re there!

Marvel at the contrast between the deep blue water shades with the lime green and orange seaweed along with the dark brown rocks. You’ll discover spectacular rock formations as you glide through the four sections of Silfra:

  • Silfra Big Crack is the narrowest section 394-ft (120 m) long, where the tectonic plates are extremely close to each other.
  • Silfra Hall is 26-ft (8 m) wide and 46-ft (14 m) deep, with more light and massive rocks on the bottom.
  • Silfra Cathedral is 328-ft (100 m) long and 75-ft (23 m) deep, where swimming feels like flying.
  • Silfra Lagoon is the 16-ft (5 m) deep section with the best visibility and bright green algae.

When you finish snorkeling, you’ll be welcomed at the surface with cocoa and cookies to warm you up as you enjoy the panorama of Thingvellir. One more reason to add this experience to your bucket list!

Important note: Participants need to be comfortable in the water and be able to swim. You are unable to participate if you are pregnant, due to the small risk of cold water entering the suit.

Weight limit: 45-120 kg
Height limit: 150 cm -200 cm

My boyfriend and I did the lava cave and snorkeling. This was our favorite day of the vacation!! Snorkeling was just an experience that can’t be described. We had Hugrun as our tour guide from Arctic Adventures and she was amazing. Then we had Matej as our snorkeling guide and he was incredible. Our trip was fantastic from start to finish!! I couldn’t believe that we actually stayed dry in the water, and boy was that water crystal clear. Just so beautiful. I highly recommend this tour. No issues at all!!

Brilliant day snorkelling Silfra!

When I found out you could snorkel in between two tectonic plates in Iceland I knew I had to re-visit the country to do it! So glad we chose this tour to go on - it was so well organised! Our driver/guide was lovely and explained how everything would work as it is quite an operation getting everyone into the snorkelling gear! The snorkelling guide was amazing - we always felt really safe with him and he made sure the whole group were together and okay the whole time. The experience in itself is once-in-a-lifetime. Although the water is -2 degrees the equipment you're given keeps you warm and dry. The only part of me that was cold was my hands but it was nowhere near as unpleasant as I expected. And of course the views are worth it. The water is crystal clear and there are some amazing rock formations and different colours to see! I recommend taking an underwater camera or gopro but they also take pictures for you to buy afterwards if you prefer.

Well worth the wait

I'd been wanting to dive silfra from the day I learned, but after 10 months away from home, diving wasn't exactly in our budget, however snorkelling with Arctic Adventures was above and beyond my expectations, I couldn't have hoped fir a better experience. Equipment provided was top notch, and our guide was a legend. Would 100% recommend

I took my girlfriend to snorkel Silfra for her birthday and it was AMAZING. Coldo was the name of our guide and his energy was infectious, he made the tour have a sense of family about it and he was very passionate about his work. Highly recommend Arctic Adventures and Coldo as a guide if you are lucky enough to get him. Enjoy Iceland!

Koldo was the BEST guide!!

We LOVED our experience at the Silfra fissure snorkel adventure. I almost wasn't able to go because of claustrophobia with the dry suit. My guide was so patient and talked me through it so I was able to enjoy the experience. It was even more beautiful in person than in the pictures. Even though the water is just above freezing, I did not feel too cold (and I am from Florida!). Overall it was an AMAZING experience that I absolutely recommend.

A memory to treasure

Its not everyday you get the opportunity to snorkle/dive in frigid and crystal clear waters in a crevice on the earth's crust and between two continental plates. Preparation and dressing up in the warm suit took over 30 minutes, and being done out in the open next to the truck carrying the suits in the parking lot, be warned that you are at the mercy of sudden rain showers as you are getting into your warm suit. There are also tight bands that needed to be put around the neck of your dry suit to prevent the freezing water from getting into your dry suit, and this is something not everyone may be comfortable with. The snorkeling itself was truly amazing and the dry suit keeps you comfortable afloat as you gaze down into the deep blue green abyss. The only sour note I had was that even though I PREPAID for photos to be taken of my wife and I before and during the snorkeling, NONE were taken, and I only found out a few days alter when they sent me photos (80% of which are stock photos of the dive site). This has yet to be fully resolved. Besides that, the snorkeling experience itself was truly one of a kind and truly unforgettable so is otherwise highly recommended.


Still got questions about the tour? Hopefully you will find the answer here.

All relevant information for the tour can be found in our snorkeling handbook.

Yes, you are allowed to bring your camera along, but we recommend to have a waterproof one if you want to have it in the water with you.

If you are planning on meeting us at the location than the meeting point is at the Silfra car park, in Thingvellir National Park.

GPS: 64°15’23.508″N 21°6’58.676″W

Please note that the National Park charges a small parking fee of 500 ISK.
We kindly ask you to be at the Silfra car park at least 15 minutes prior to your tour starts,

Our guides normally have an underwater camera and usually, take photos during the tour. If you are interested in photos please let your guide know before you go into the water.

You can then buy the photos from your guide at the end of the tour, for a price of 3 900 ISK, which includes all the photos from that day. Kindly note that photos cannot be guaranteed. Our customer’s safety and wellbeing is our first priority, and therefore the guide will focus on snorkelers as a priority when in the water and will be taking photos when everyone is comfortable.

Unfortunately, you cannot wear glasses as the glasses don’t create a seal between your face and the mask. We recommend wearing contact lenses instead.

You are not allowed to participate in our snorkeling tour if you are pregnant as it can put your baby in high risk.

Yes, you must be able to understand English to a participant. The tour is directed in English.

Some snorkeling tours match with a dive tour, and then you will be in the same area at the same time. You will, however, be in separate groups with separate guides, and won’t be in the water exactly at the same time.

You need to be more than 12 years old ( guardian’s approval needed for minors under 18) and you need to know how to swim independently. Because of the dry suit sizes, there are height-weight limitations. The minimum height is 150 cm, and the minimum weight is 45 kg. The maximum height is 200 cm, and the maximum weight is 120 kg.

The minimum height is: 150 cm (4’9)

The maximum height is: 200 cm (6’5)
The maximum weight is: 120 kg (265 lbs)

Yes, you must be able to swim independently without a lifejacket and feel comfortable in the water to take part in the tour.

It is a magical experience. When snorkeling you will be wearing a dry suit, hood, and gloves made of neoprene, along with fins, mask, and snorkel. This equipment will make it not only possible but as well very enjoyable to stay in the water despite the cold temperature. Tripadvisor recently rated Snorkeling at Silfra as one of the Top 5 travel experiences in the world. 

No, you do not need any previous experience to snorkel, however, it is important that you can swim independently and feel comfortable in the water.

We highly recommend long underwear and some warm socks. Wool or fleece is the best material to wear. You’ll be wearing the clothing under the dry suit.

We provide you with high-quality neoprene dry suit so that your body stays dry. There is always a small risk that water can enter the dry suit, that is not dangerous but you can feel a little cold, therefore, we recommend you to bring an extra spare set of clothes and a towel, just in case. Note that your hands and face will get wet, which is completely normal.

You will be provided with high-quality neoprene dry suit from Waterproof International and O’Three. As well as neoprene hood and gloves to protect your head and hands from the cold. You’ll also be given fins, mask, and snorkel.

Our client to guide ratio is 1 guide for every 6 snorkelers

The water temperature is 2-4 degrees C (35-37 degrees F) all year round.

Yes, there are two toilet facilities at Silfra.

Occasionally fish venture into Silfra from Þingvallavatn lake, but they will quickly swim back as they don’t like the cold glacier water. However, there is a lot of colorful seaweed including a bright green variety known as ‘’troll hair’’, which makes the fissure unlike anything on the surface.

Silfra can be up to 60m deep. However, when you’re diving in Silfra than you will go about 7 to 12m deep, and the maximum diving depth that is permitted is 18m.
