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.

Disclaimer: All dive trips are undertaken on the responsibility of its participants. 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

Free cancellation until 24 hours before departure; no refund after that. If the operator cancels for weather or safety, you get a full refund or a new date.

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.

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.
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.
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 Wetsuit Snorkeling in Silfra - with underwater photos / From Reykjavik from Adventure Vikings is €136 — €377 less. Here is every difference we can actually measure.

	Arctic Adventures · €513	Adventure Vikings · €136
How long it runs	7 hours	4.5 hours
Getting there	You make your own way	Picks you up
Changing your mind	Free until 24 h before	Free until 48 h before
How hard it is	Demanding	Easy

The cheaper tour is ahead on more of what we can measure. The €377 is worth it only if 2.5 more hours out is what you want.

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!

What a wonderful adventure! The 3 Day South Coast/Golden Circle tour included all of the sites we wanted to see and it did not disappoint. We were picked up at a bus stop in downtown Reykjavik and our journey began with about 16 other guests, a good group size. Our tour guide "Good" John did an excellent job teaching us about the history of Iceland and the sites we saw. The tour is well organized with just enough time at each site. He also made adjustments to the itinerary based on the weather as well as including sites not on the tour to give us more to see, which we loved! There were plenty of bathroom/food breaks as needed and we loved that we could just sit back, relax, and enjoy the views outside the window rather than worrying about driving and parking. Our multi-day tour included a 2 night stay at Adventure Hotel Geirland, which Arctic Adventures owns. Such a quiet hotel, convenient location with beautiful views. Our only complaints were that the shower leaked and made the floor wet, and that dinner at the restaurant was expensive with limited options. However the food was good and breakfast was included. The Katla Ice Cave was our favorite part, which was partnered with Southcoast Adventure, and our guide Inga was very friendly and knowledgeable. We did pay for a hiking boot rental for my husband but never received the boots. We did not ask our tour guide so we are not sure what happened with that. Overall we absolutely loved this tour and would highly recommend Arctic Adventures to anyone visiting Iceland for the first time!

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.
