About this experience

Diving day tour in Silfra Fissure in Þingvellir National Park in Iceland

Trip Difficulty: 4/5, demanding.

Please check out our Deep Into the Blue from Þingvellir tour if you have your own car rental and would like to meet us on location.

Tour Highlights: Þingvellir National Park (Thingvellir National Park), Silfra Fissure, Diving, North American and Eurasian tectonic plates. 

- Bad eyesight? Since you are wearing a snorkeling / dive mask to see underwater there can be nothing in the way of the seal to keep them from filling up with water. That is, you can not wear glasses underneath the mask. You will have to go without them, wear eye lenses or bring your own mask with prescription.
- Requirement: Open Water certification and Dry suit certification from any internationally recognised dive agency, For example PADI, SSI, CMAS, NAUI etc.
- Driving directions: If you are meeting us on location, the meeting point is on the Silfra car park, located in Thingvellir national park. For GPS: 64°15’23.508″N 21°6’58.676″W

This world class dive tour includes diving in Silfra ravine, one of Iceland’s best-kept secrets. It is situated in the heart of Þingvellir National Park, the founding place of the world’s oldest parliament and a UNESCO world heritage site. Silfra is an otherworldly scene located in the lava field directly on top of the continental rift valley between America and Europe. 

The slow current gives one a perfect pace to explore this beautiful area. The fresh water visibility is an unmatched specimen, so wide and long that sometimes it is only limited by the density of the water itself. Depth varies from 10 to 40 meters. Our dive depth is limited to 18 meters by park regulations. 
PLEASE NOTE: In the winter time if the temperature falls below -0°C we will only do one extended dive. This is because the dive equipment will freeze up when we exit the water.

You can add a PADI Dry suit certification for 54.500 ISK. Please contact our sales department for further information about dry suit certification.

Arctic Adventures does not assume any responsibility for accidents which are caused by its customers or can be traced to there own actions. Participants have to sign a waiver before undertaking all trips stating that they realize that all outdoor activities carry an inherent risk.

Cancellation for this tour

If the weather cancels this tour

Iceland's weather is real. What usually stops this one is rarely: Silfra is spring-fed and sheltered, but access can close in a storm. Here is exactly what happens to your booking.

  1. 1Arctic Adventures decides, and tells us. Operators cancel when it is unsafe or pointless, and we back that call every time — we do not ask them to run anyway.
  2. 2We contact you by email, and by phone if your tour is the same or next day. You choose: another date if there is one you can make, or a full refund. There is no fee and nothing to argue.
  3. 3The refund goes back to the card you paid with, through Stripe, usually visible within a few working days. If this tour was one of several in your booking, the others are untouched.

What you do not get is the day back. If this is the only free day in your plan, put a spare day next to it — the planner leaves days free with the rest-day option. And if you want out because the forecast looks bad, that is your own cancellation: free until 1 day before departure, the operator's policy after that.

Why this one and not the cheaper one?

The nearest cheaper Silfra Snorkel tour from Freedive Iceland is €100 — €401 less. Here is every difference we can actually measure.

Arctic Adventures · €501Freedive Iceland · €100
How long it runs7 hours3 hours
Changing your mindFree until 24 h beforeNot stated
How hard it isDemandingVery easy

The €401 buys you 4 more hours out and free cancellation up to 24 h before. Whether that is worth it is your call — but that is what the difference is.

Sold out on your date?

Seats come back — a cancellation, or the operator adding a vehicle. Tell us the date and we will check once a day and email you if one opens. One email, then we delete the address; nothing else is ever sent to it.

Who this is not for

  • Not for families with children under 18 — the operator will not take them, even with a parent.
  • Not for anyone unsure on their feet or carrying an injury — the operator rates this as physically demanding, and there is no easy version of the day.

Read off the operator's own conditions. If none of it applies to you, this is a good one.

    This was a phenomenal trip with AMAZING sights. Our tour guide was informative, friendly, and easy to listen to. You will learn a lot and see nature at its greatest. We absolutely loved this tour and would recommend it to anyone. The car ride is comfortable and there is wifi as well! Shout out to our tour guide, Magnus (I hope I’m spelling his name correctly), who told us some hilarious stories.

    I spent six days on a bus tour around Iceland with a professional guide. It was an excellent opportunity to gain a comprehensive overview of Iceland's breathtaking nature while also learning about the country's history and the everyday lives of its people. Iceland's landscape and animals are truly unique, featuring magnificent waterfalls, geysers, whales, seals, puffins, volcanoes, glaciers, and mountains. Every day brought new and unforgettable experiences. Of course, none of this would have been possible without our guide, Viko. He not only drove the bus safely but also shared fascinating stories about Icelandic history, culture, and way of life. He was willing to tailor the itinerary to our group's interests and wishes, making the experience even more enjoyable. I am very grateful for his professionalism, knowledge, and enthusiasm in interpreting Iceland's natural and cultural heritage. He played a key role in making this tour such a memorable experience.

    I did the Iceland South Coast Full Day Small-Group Tour from Reykjavik. Such an amazing tour and one of the highlights of my trip to Iceland! Our guide, Erik, was incredibly knowledgeable and shared so much interesting information about Iceland throughout the day. We visited some of the country’s most beautiful sights, including stunning waterfalls, Vik, black sand beaches, and other breathtaking stops along the South Coast. The pickup process was simple and organized, making the day completely stress-free. The scenery was incredible from start to finish, and Erik helped make the experience even better with his knowledge, friendliness, and enthusiasm. If you’re visiting Iceland, the South Coast is a must-do, and I highly recommend taking this tour with Erik as your guide!

    A Fantastic Trip: Review of 3-Day Golden Circle, Ice Cave and Glacier Lagoon Absolutely incredible experience with Arctic Adventures and the guide Hjalti Bjornsson. The pick up from the bus stop was easy and the instructions were super clear. Be aware that they are extremely punctual at every stop. Do not be late by even a minute. We saw so many sites and the weather was perfect for most of the days. Our guide even took us on some stops that were not in the itinerary, but ones he thought were interesting and on the way, like the power plants and some other glaciers. The bus ride was very smooth with plenty of room and the seats were comfortable. The itinerary was well thought out with a great mix of light walking about 3 - 6 miles per day depending on how much you wanted to walk to each site. Some sites like the glacier Skaftafellsjokull (optional) were further away (4 ish miles), while others were much closer (1000ft). The hotel was situated in a beautiful location with sheep everywhere and interesting rock formations. The hotel was very comfortable with hot water and plenty of space to spread out. Our guide was extremely friendly and knowledgable. I would highly recommend this trip for anyone between the ages 10 - 70. However, this might not be the best experience for those with mobility issues as there is walking to some of the best sites.

Silfra snorkelling & diving — questions people ask

How cold is the water at Silfra?

Two to four degrees Celsius, all year. It is glacial meltwater filtered through lava for decades, which is why visibility runs to a hundred metres. You wear a dry suit over a thermal undersuit, so your body stays dry and warm. Your face, lips and hands are the parts that feel it, and after thirty to forty minutes in the water most people are ready to get out. Hot chocolate afterwards is standard.

Do I need to be a strong swimmer to snorkel Silfra?

No, but you must be comfortable in water. The dry suit floats you, so you drift along the fissure with a gentle current doing most of the work. You do need to be able to swim, and operators set minimum age, height and weight limits and ask about medical conditions on a form. Check the tour page for the current limits before booking. Glasses cannot be worn under the mask; contact lenses are fine.

Is Silfra snorkelling worth it in winter?

Yes. The water is the same temperature in January as in July, and the visibility is the same. What changes is the air: getting into and out of the suit at minus five with wind is unpleasant, and daylight limits the departure times. Fewer people snorkel in winter, so the fissure is quieter. If you are here between November and February and want it, book the earliest slot for the best light.

Can I dive Silfra without a dry suit certification?

Not on a standard dive tour. Operators require a dry suit certification or a logged number of dry-suit dives within the last two years, plus an open-water certificate. If you have neither, the two-day PADI dry suit course with a Silfra dive (/experience/19038/) gets you certified and in the fissure. Snorkelling (/experience/208/) has no certification requirement and shows you the same rock walls from the surface. Most people are happy with snorkelling.
