    About this experience

    The Silfra Fissure is more than a snorkelling site - it is a surreal passage between two continents! Slip into the clearest water on Earth and watch a hidden world unfold around you. You’re gliding through a cathedral of rocks and shimmering blues, surrounded by volcanic rock walls that drift apart 2cm every year. Few places on the planet let you feel so connected to the forces that shape the Earth. Our expert guides are trained to ensure your safety and confidence in the water, so you’re free to focus on the wonder around you. This is not a typical swim, it’s a once in a lifetime adventure into the heart of Iceland.

    A highlight of our Iceland trip!

    A great experience booked directly through Arctic Adventures, who was helpful every step of the way. Our smart, funny guide, Valentina, was an excellent instructor, making sure we put on and used our gear safely and properly. The swim and snorkeling through the fissure was beautiful and magical. I highly recommend both the snorkeling and Artic Adventures!

    Not worth the time. Do other activities in beautiful Iceland

    Far too crowded and the dry suits were very uncomfortable. As an avid scuba diver, I was really looking forward to this experience. It fell way below my expectations. Not only was the weight far too long, my son‘s wetsuit must’ve had a hole because he was soaked with freezing cold water by the end of the half hour tour. While the tour guide was informative and entertaining, the tour itself was way below expectations. I would not recommend this experience to anyone who enjoys true scuba diving experience. The dry suit causes you to float like you’re in a balloon and lose your balance, making a whole experience quite uncomfortable. Finally, there’s almost nothing to see as it’s purely rocks and some algae during the entire snorkeling experience.

    A Must for your Itinerary

    This is absolutely worth the money. Truly a once in a lifetime experience. All of the equipment was provided and our tour guide, Carol, was excellent. She did a great job of making it an exciting environment, and a great job of explaining everything. 10/10 would do again.

    Response from the operator: Hi Matthew, really glad the experience made the itinerary. Once in a lifetime and would do it again is a fun contradiction only Silfra creates. Arctic Adventures Team

    Great snorkeling experience

    Arianna was an amazing guide. Very knowledgeable and had a great personality. They help you get into your suit and teach you all the basics. The views are out of this world.

    Response from the operator: Hi Nicole, glad the guide made the whole thing easy from suit-up to the water. When someone's got a great personality and knows their stuff, the cold barely registers. Arctic Adventures Team

    Silfra Fissure Guided Snorkeling in Thingvellir with Free Photos: questions travelers ask

    Practical detail on this experience, plus the wider planning questions for Reykjavik.

    How much does Silfra Fissure Guided Snorkeling in Thingvellir with Free Photos cost?

    +

    Prices start at $141 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Reykjavik usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.

    How long does Silfra Fissure Guided Snorkeling in Thingvellir with Free Photos take?

    +

    Plan for about 3 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Reykjavik is not rushed.

    Is Silfra Fissure Guided Snorkeling in Thingvellir with Free Photos worth it?

    +

    It holds an Outty Ranking of 81 out of 100, which we label "Exceptional". That score blends traveler sentiment (4.7/5 across 728 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Reykjavik, and how flexible the cancellation terms are.

    Can I cancel or reschedule Silfra Fissure Guided Snorkeling in Thingvellir with Free Photos?

    +

    Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.

    Is Silfra Fissure Guided Snorkeling in Thingvellir with Free Photos suitable for kids and families?

    +

    Yes, all ages are welcome. Families should still weigh the 3-hour running time, and strollers are easier on the earlier, quieter departures.

    How far in advance should I book Silfra Fissure Guided Snorkeling in Thingvellir with Free Photos?

    +

    Around 255 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Reykjavik can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.

    What should I bring or wear?

    +

    Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Reykjavik and add a light layer if any part of the 3-hour experience runs outdoors or after sunset.

    Where does Silfra Fissure Guided Snorkeling in Thingvellir with Free Photos start and how do I get there?

    +

    The exact meeting point and directions are on your voucher once you book, and they sit in central Reykjavik within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.

    What are the best things to do in Reykjavik?

    +

    On Outty we rank every Reykjavik experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Reykjavik Food Walk - Local Foodie Adventure in Iceland, Small-Group Golden Circle, Blue Lagoon with Ticket & Kerid Crater, Reykjavík Small group Walking Tour - by CityWalk. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.

    When is the best time to visit Reykjavik?

    +

    Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.

    How many days do you need in Reykjavik?

    +

    Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.

    Do I book through Outty or through the operator?

    +

    Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
