How fit do I need to be?

Participants need to be comfortable in the water and be able to swim . You cannot participate if you are pregnant, due to the small risk of cold water entering the suit. To join the tour, you must read and sign the medical statement form before booking. If you have any medical conditions, medical approval from a doctor is required. A slow, beautiful glacial current flows through the fissure, guiding you effortlessly during the first half of your snorkel. In the second half, you may need to swim against this gentle current— while not difficult, it does require basic swimming ability. Dry suit sizes: While the guides would like everyone to join the tour, the gear sizes reflect what’s available on the market, and it’s important that guests fall within the size parameters. This ensures the safety equipment can do its job and keep guests warm in the glacial water. Weight limit: 99-265 lbs (45-120 kg) Height limit: 4’11” – 6’7″ (150-200 cm) On the Lava Cave & Silfra Snorkeling Combo , the same swimming and sizing requirements apply for the Silfra portion, plus a couple of hours of walking through the lava cave beforehand—easy underfoot, with no climbing or scrambling involved. Note that filling out and signing a medical statement form about your general health is required. If your health condition makes the adventure unsafe for you, the guides reserve the right to deny participation for your safety.

Is this snorkeling adventure for me?

Please consider the following and make sure you’re comfortable with all of it: Participants wear a tight and constricting full-body dry suit, which is heavy and may make walking difficult. Due to the geographical layout of Silfra, participants must walk approximately 150 meters (490 ft) in full gear to the entry point and later 350 meters (1,150 ft) from the exit stairs back to the starting area. The dry suit has tight seals on the neck and wrists to prevent water from entering, which is essential for staying dry in glacial water. However, these seals can feel restrictive and may be uncomfortable for those who are claustrophobic. The snorkeling experience lasts about 30-45 minutes, with water temperatures around 2°C (35.6°F), so it is recommended to eat and drink before the tour. Participants wear a neoprene hood and semi-dry neoprene gloves. While this is a snorkeling tour, it is important to note that your face, hair, and hands will get wet. There is a slight current in Silfra, and participants must be comfortable swimming against it during the final part of the tour. A snorkel is used for breathing throughout the activity, with one end in the water and the other in the air. Iceland’s outdoor temperatures can be extremely cold, especially in winter. You will spend up to three hours outside, so dress warmly with thermals, a winter coat, hat, and gloves. There are no locker rooms at Silfra, so avoid bringing valuables or unnecessary items on the tour. Note that filling out and signing a medical statement form about your general health is required . If your health condition makes the adventure unsafe for you, the guides reserve the right to deny participation for your safety.

What do I need to bring?

Here’s a list of the equipment you need to bring: Thin thermals Warm socks Warm undergarments Spare clothes for layering and change of clothes Waterproof rain jacket Towel Camera — optional (but recommended) All snorkeling equipment, including an undersuit, dry suit, hood, gloves, mask, snorkel, and fins will be provided by your guide.

Do I need previous experience?

No. No snorkeling, diving, or caving experience is necessary for either tour—your guide leads the way and handles all the gear. You just need to be comfortable in the water and able to swim.

What kind of equipment is included? Do I need to bring anything of my own?

Your guide provides everything you need to get in the water: a drysuit, thermal undersuit, neoprene hood, neoprene gloves, mask, and fins . On the Lava Cave & Silfra Snorkeling Combo , you’ll also get all the necessary caving gear and safety equipment for the cave portion. On your end, bring warm base layers (wool or fleece) to wear underneath the suit, thick socks, a change of clothes, and a towel for afterward. If you wear glasses, bring contact lenses instead — glasses don’t fit under the mask.

What's the Silfra fissure water temperature?

The water in Silfra sits at 2-4°C (35-37°F) year-round , so it’s cold in every season, not just winter. The drysuit and thermal undersuit keep your body warm and dry; only your face, hands, and part of your hair get wet.

Iceland Snorkeling Adventure: Silfra Fissure at Thingvellir National Park

From $145 ()

Thingvellir National Park is where Iceland’s history and geology collide: the site of the country’s original parliament, and the exact seam where the North American and Eurasian tectonic plates are pulling apart. Between them lies the Silfra fissure, filled with glacial meltwater so pure and cold it’s been naturally filtered through decades of lava rock, with visibility stretching past 100 meters (328 feet). Suit up in a drysuit and float the length of it, close enough to touch two continents at once. If a couple of hours in the water isn’t enough, pair it with a morning underground in one of Iceland’s longest lava caves before you get in.

Adventure Highlights

Snorkel between continents: Float through the Silfra fissure, where you can touch the North American and Eurasian tectonic plates on either side of you
Some of the clearest water on Earth: Glacial meltwater filtered through lava for decades gives Silfra visibility over 100 meters (328 feet), even in the middle of winter
Add a lava cave to the day: For those who want more than just the water, the combo tour opens with a guided walk through Iceland’s longest lava cave before you snorkel

Mario Osenk

I had an amazing experience snorkeling at Silfra on 29 September with our guide, Dominika! The tour was exceptionally well-organized, and Dominika made the whole experience fun, safe, and educational. She ensured everyone was comfortable and enjoying themselves. The views underwater were breathtaking, and the crystal-clear water made it an unforgettable adventure. Highly recommend this tour and guide!

Stephanie Huss

We are so glad we signed up for this tour. Our guide, Sara, was warm – funny – friendly, and very knowledgeable. The company website was very transparent about what to expect and how to determine if this was the right tour for customers. We received reminders about what to expect and what to bring with us by email. Company communication was very good. The other guides we observed and interacted with were also very enthusiastic and helpful to any customer, no matter which group they were in. We stayed safe and dry, and were able to see an incredible part of the planet!
