Journey to the heart of Thingvellir National Park, to take the most incredible dive of your life: you will be snorkeling inside The Silfra Fissure, one of the most amazing places in the world. 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. The Silfra Fissure was named as one of the Top 5 activities in the world by TripAdvisor.

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 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.

Want photos from the snorkeling tour?

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).

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.

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.


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

No, you don’t need any prior snorkeling experience. However, you’re required to know how to swim and be comfortable in the water in order to snorkel in Silfra.

Yes, you should be able to swim independently and feel comfortable in the water. However, you don’t have to be a strong swimmer to enjoy snorkeling in Silfra. If you know the basics, you’re good to go!

Yes, the requirements are as follows:

  • Must be at least 12 years old 
  • Participants under the age of 18 must be accompanied by a parent or an adult guardian booked on the same tour
  • Height limit is 4 ft, 11 in (150 cm) to 6 ft, 7 in (200 cm)
  • Weight limit is 99 lb (45 kg) to 265 lb (120 kg)
  • If you don't fall within these parameters, we won't be able to provide you with suitable equipment
  • Snorkeling involves a moderate level of exercise, you must be reasonably fit 
  • If you’re pregnant, you will not be allowed to participate due to the small risk of cold water entering the suit
  • It’s important that you can both understand and communicate in English in order to participate in the tour
  • All participants are required to read over our snorkeling handbook prior to going on the tour
  • The snorkeling handbook includes important information regarding medical conditions that are not allowed in Silfra, etc.

We recommend wearing a thin thermal base layer and warm socks. Materials like wool, fleece, or synthetics work best. The main goal is to wear something that will keep you warm. Cotton is not recommended.

We provide you with two layers of clothing: a thermal undersuit and a neoprene dry suit. We also provide you with a mask, a snorkel, fins, a wetsuit hood, and wetsuit gloves.

We use top-notch dry suits made by Waterproof or 0´Three, we’ll do our best to find the best fit for you. There is still a small chance that some water can enter your dry suit. Don’t worry, it's not dangerous but it will feel a little cold. 

Just to be safe, we recommend bringing a change of clothes and a towel. While you’re snorkeling, your face, hair, and hands will get wet, but that’s normal and shouldn’t make you too cold.

Typically, we spend about 30-45 minutes snorkeling in the Silfra Fissure. After we finish our route, you can choose to either get out of the water or swim around a bit longer and explore the Silfra Lagoon.
