If you’re eyeing Iceland’s natural attractions, snorkeling in the Silfra fissure might not be the first thing that springs to mind. Yet, this underwater adventure consistently earns glowing reviews, and for good reason. We’ve looked into what makes this experience so popular and whether it’s worth the $152 you’ll spend.
Two things stand out for us: first, the unmatched clarity of the water—sometimes over 100 meters visibility—and second, the knowledgeable guides who make you feel safe and well-informed. On the flip side, a significant consideration is that the experience requires wearing a snug wetsuit or drysuit, which can be uncomfortable for some, especially if you’re not used to tight gear.
Still, if you’re comfortable in water and eager to see one of Iceland’s most extraordinary natural features, this trip is a solid pick. It’s especially suited for adventure seekers who want a once-in-a-lifetime experience that combines stunning scenery with a touch of thrill.

Meeting Up and Preparing
Once you arrive at the designated meeting point at Silfra (the Viking7V4M+HG8 address in Thingvellir), you’ll be greeted by your guide—likely a PADI-certified expert. This initial meet-and-greet is about sharing what you can expect and ensuring everyone is comfortable with the process. The group size maxes out at six, which means personalized attention and a relaxed atmosphere.
You’ll then get fitted with all your gear—snorkeling equipment, wetsuit or drysuit, and thermal socks to keep your feet warm. Many reviewers highlight the importance of thick socks, as feet tend to get cold quickly. After this, safety briefings are brief but thorough, emphasizing how to navigate the water and what to do if you need assistance.
Entering the Water: What to Expect
Once suited up, you’ll wade into Silfra’s famously icy but crystal-clear waters. The water’s clarity is largely due to meltwater from nearby glaciers filtering underground for about 50 km before reaching the fissure. This underground journey results in visibility that can make you feel like you’re floating in a giant aquarium.
During the roughly 30-40 minutes in the water, you’ll see down to astonishing depths—often 42 meters—making it feel like floating in space. You might feel a bit cold initially, but the dry suit or wetsuit, plus thermal socks, do a good job of insulating you. Several reviews mention that the dry suits keep you dry up to 95%, and that the experience isn’t as cold as you might think.
Your guide will take photos throughout—typically 40-100 shots—and doesn’t charge extra for this service. Many reviewers mention how these photos help encapsulate the trip, and you get to download them after a few days, which turns out to be a lovely bonus.
Post-snorkel Warm-up and Reflection
After your snorkel, you’ll return to the meeting point and be treated to a well-earned hot chocolate. It’s a relaxing way to warm up and reflect on the experience, especially after being in chilly water. The combination of stunning visuals underwater and a warm drink makes for a satisfying finish.

The Unparalleled Beauty of Silfra
The main selling point of this tour is easily the extraordinary water clarity. With visibility often beyond 100 meters, you’ll be able to see the underwater landscape in astonishing detail. The water’s purity stems from the meltwater from glaciers melting and traveling underground, filling the fissure slowly over time.
One reviewer likened snorkeling here to “seeing down 42 meters” and called it “wonderful” to watch friends float around in the water. The experience of floating between the North American and Eurasian tectonic plates adds a geological marvel to the visual spectacle.
Expert Guides and Safety
Your guides aren’t just there to help you with gear—they’re trained professionals who know the area inside out. Multiple reviews praise their helpfulness, knowledge, and friendly demeanor, which makes even nervous first-timers feel at ease. One reviewer mentions, “Jane made it worth it!” highlighting how a calm, reassuring guide can change an experience from intimidating to incredible.
Equipment and Comfort
All necessary equipment is included, and the choice between wetsuit and drysuit caters to comfort preferences and weather conditions. The drysuits are highly recommended—many reviews state they keep you dry and comfortable, making the cold waters more manageable.
While the drysuit can feel tight and sometimes uncomfortable around the neck and wrists, many agree it’s worth the trade-off for warmth and dryness. One tip from experienced snorkelers: bring thick socks to keep your toes warm, as feet are often the first to get cold.
Small Groups for a Personal Touch
Limiting groups to just six participants means everyone gets tailored attention. With fewer people, you don’t feel rushed or crowded, which enhances the overall enjoyment. This small-group setup is a big plus for those who prefer a more intimate experience.
Photos and Memories
The inclusive nature of photo-taking is a big deal for many. Instead of paying extra, you’ll receive a generous collection of photos taken during the tour. It’s lovely to have these visual memories—many reviewers use words like “wonderful” and “amazing” to describe their photos.
Who Would Love This Experience?

This snorkeling tour is a natural fit for water lovers, adventure junkies, and anyone curious about Iceland’s geological quirks. You’ll enjoy it most if you’re comfortable swimming and don’t mind wearing tight gear. It’s not ideal for those who have trouble in water or dislike cold environments, but the dry suits do a good job of insulating.
While not explicitly marketed as family-friendly, the minimum age is 12, making it accessible for older kids who can handle the cold and noise of water. People over 65 should check with the company, as a medical approval might be needed.
If you’re looking for a unique, visually stunning experience that combines nature, geology, and adventure, this snorkel in Silfra is worth considering.
