About this experience

Our 7-step rejuvenating Sky Ritual brings this culture to life for every guest and is included in the Sky Lagoon experience. Pure Pass includes admission, the Sky Ritual and public change facilities.

Cancellation for this tour
Free cancellation until 2 days 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.
- 1Adventure Vikings 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 2 days before departure, the operator's policy after that.

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 12 — the operator will not take them, even with a parent.
Read off the operator's own conditions. If none of it applies to you, this is a good one.

We had a most excellent driving tour of the Golden Circle. This included lunch at Fridheimar Tomato Farm which was fabulous. The tour was educational and highly enjoyable. I highly recommend this tour. Our guide was Gretar and he was an excellent tour guide.

We had a lot of fun with Adventure Vikings. The pick up was smoothly handled and given the snowy conditions I was glad not to be driving. We weren’t too cold at all thanks to drysuits (even though we looked like Patrick from SpongeBob!) and the snorkelling was super cool and easy. Thanks Gretar! Susan and Harry 🙂

We just got back from the Silfra snorkeling tour. It was incredible! Our guide Arnie was phenomenal. Everything was organized, educational and supported. We were very excited and had an awesome experience.!! Other than the not great weather with rain and chill… The experience was awesome and the water didn’t even feel cold because we were so prepared! You should go!! Our water photos aren’t ready yet or I would add them!

Best experience ever. And adventure Vikings are amazing. I had a change in travel plan at the last moment, but the team accommodated me very nicely and with understanding. Special thanks to Bjarki for being so responsive on email. Also thanks to Kaya, who has been an amazing guide through out the adventure. She has good knowledge about the area and also the activity. She later shared some of her favourite places in Iceland for us to visit, which were amazing. Also, the GoPro pictures were amazing and she is fun. I would recommend booking your trip with them.

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.
