Even though this is a bit expensive, this activity is totally worth every penny! This is really a once in a lifetimw activity. Under water views are amazing; nothing like you’ve ever seen. Water is clear and cold, but we get used to it. Our guide AnnaSara was really friendly and kind. She really took the time to talk with us and did not make us feel in a rush. Small group is the best option. I would totally recommend this tour with AnnaSara as a guide 🙂 under water pictures are a plus too, they are amazing!!

Amazing Drysuit snorkeling through The Silfra fissures. Iceland Advise has super employees like our guide Christina. A must see and do when visiting Iceland.

I was actually able to book my snorkeling trip while in Iceland two days prior to arrival at Silfra. I was extremely fortunate to have a tour guide all to myself, as I was the only one scheduled for that particular time. Matias was wonderful! All of the tour guides were wonderful. It was definitely one of the most beautiful adventures that I was able to experience in Iceland.

My teenage son really wanted to snorkel Silfra. I am an avid warm water snorkeler but had never worn a dry suit, hate crowds and cold. We looked for a small group tour and really loved this experience. Cordelia was kind, well prepared and made the experience perfect. Thanks again!

Our guide, Weston, was very informative and made sure that everyone felt comfortable, safe and had a good time. Groups are kept small - were just a group of 5. Weston sent us photos which he took during our snorkeling tour within just a few hours of leaving the park and the photos are fantastic. He even sent us a list of things to do around the island during our road trip. Silfra is a beautiful place and the tour with Weston was a great experience and highly recommended.

I hesitated a lot before doing it, and i don't regret it at all ! I met Weston at the visitor center and asked him if he could add me to his group at the last minute, which he did. Swimming among the rocks in such a clear water is clearly a unique experience. And those dry suits keep you warm all the way. Weston is an awesome guy, lots of stories to tell about the place and very friendly. Thank you again !

Frequently asked questions

All you need to know about snorkeling & diving in Silfra, Iceland

Snorkeling and diving tours run all year round, so you can explore Silfra no matter when you’re visiting Iceland.

Silfra has the reputation of holding some of the clearest water on planet Earth! Here’s why: The glacial meltwater from nearby Langjökull is filtered for somewhere between 30 and 100 years through porous underground lava, which it turns out is an exceptional filtration system. Once it flows into the fissure, the water is super pure and crystal clear. A mild current moves any particles kicked up by snorkelers or divers out into Lake Thingvellir, so Silfra returns to its pristine state within just a few minutes. Amazing!

Silfra is filled with glacial meltwater, and it stays right around 2-4° C/35-37° F all throughout the year. But don’t worry, your gear will keep you warm and comfortable. Plus, many of the tours offer hot drinks and cookies when you’re done in the water to warm you up!

YES! As pure, filtered glacier water, it’s perfectly safe and we highly recommend that you try a sip as you explore the fissure.

The tours have a maximum group size of 6 participants.

If you don’t require pick up and will be meeting us on site, please park in the P5 parking lot and then walk back to the Silfra car park, (about 400m) where all the snorkeling/diving vans are.You can put these coordinates into your GPS: 64°15’23.508″N 21°6’58.676″W.Please arrive at the Silfra car park at least 10 minutes before your tour is set to begin, so you can check in and meet your guide.

Snorkeling tours:

  • Not including pick up and drop off times, the Silfra tours last about 2-3 hours. You’ll spend about 30-40 minutes snorkeling in the fissure.

Diving tours:

Yes, you’ll need to be able to understand and communicate in English for your snorkeling/diving tour.

Minimum age requirements for snorkeling vary from 12-16, depending on the tour. Minimum age requirements for the diving tours are 16-17, depending on the tour. Please check each tour’s main page to find specific age requirements. Participants under 18 must be accompanied by a parent or guardian. The maximum age is 65, but if you’re over 60, you will need a medical waiver.

Yes. In general, you must weigh between 45 and 120 kg (99 and 264 lb), and be between 145 and 200 cm (4’9” and 6’7”) tall. Requirements vary by tour, so please see details on the main page of the tour you’re interested in. If you have any questions, don’t hesitate to contact us!

Yes, you must know how to swim for the snorkeling/diving tours. The drysuits are buoyant, but it’s very important that you’re able to swim independently.

Nope! It’s no problem if you’ve never snorkeled before…except that your future snorkeling experiences might pale in comparison to Silfra. 😉 Please remember that you must know how to swim independently.

For the diving tour in Silfra, you’ll need to be a certified diver at the level of PADI or above. You’ll also need to have a dry suit diving certification and a logged dry suit dive within 2 years of the tour date, OR have at least 10 logged dry suit dives within two years of the tour date, with written proof from a diving instructor.

On the Silfra Day Tour, the guides always aim for two dives. However, if it’s very cold outside (below 0°C/32°F) it’s only safe to do one dive, because the equipment freezes after the first dive.

On diving tours, the dive depth depends on the qualifications and experience of the participants, but typically you’ll dive to a depth of about 10 meters or 32 feet. The maximum dive depth allowed is 18 meters, or 60 feet.

If you’re snorkeling in a drysuit, you’ll float along the surface as you look down into the fissure. If you choose a tour with a wetsuit, you’ll have more mobility and be able to free dive down underneath the surface.

For safety reasons, you can’t participate in a snorkeling or diving tour while pregnant.

Sorry, glasses aren’t a good idea because they don’t allow the mask to work properly— you won’t get that watertight seal. Contact lenses are fine!

It depends on whether your tour uses a wetsuit or a drysuit. If you’ll be wearing a drysuit, you should wear warm long underwear and socks—wool or fleece are best. You’ll keep these on under the suit. Please bring extra socks and a change of clothes. Although the suits are designed to be water-tight, sometimes a bit of water can seep in. This is rare, but it’s better to bring extra clothes! If you choose a wetsuit tour, please bring clothing that’s appropriate to wear under the suit, such as a swimsuit or tight-fitting thermal lycra or neoprene clothing. Remember that wetsuits will give you more freedom, but won’t keep you as warm as a drysuit. No matter what type of suit you choose, your hands and face will get wet!

Yes! You’ll definitely want photos of your adventure. A word of caution: if your camera is not waterproof, it will get ruined, so either bring appropriate protection for your equipment or consider investing in a waterproof camera. On some tours, GoPro rentals are available—you’ll find this in the “Extras” section of the booking sidebar.

Why book a snorkeling tour?

Because there’s truly nothing like snorkeling in the Silfra fissure… Once you suit up and peek underwater, you’ll understand what all the hype is about! This is one experience you can’t miss during your Iceland adventure- especially since Silfra is only about an hour from Reykjavik.
