When you think of snorkeling, warm tropical waters probably come to mind—but what if I told you some of the world’s most extraordinary snorkeling happens in near-freezing water?
Picture yourself gliding through crystal-clear glacial waters, with visibility so pristine you can see over 100 meters ahead. Welcome to Silfra, a magical fissure in Iceland’s Þingvellir National Park. It’s the only place on Earth where you can snorkel between two tectonic plates.
That’s right—Silfra is nestled in the gap between the North American and Eurasian plates, making it one of the most unique experiences on the planet.
Why Silfra is a Must-Visit
Silfra’s stunning underwater landscapes are like stepping into another world. The glacially fed water showcases vibrant shades of blue and green that shimmer in the sunlight, creating a scene so surreal it feels like swimming in a dream. The water is not only breathtakingly clear but also some of the purest on Earth—it’s so clean, you can take a sip as you swim! Talk about refreshing!
And while the water is cold (hovering around 2–4°C or 35–39°F year-round), the dry suits provided by tour operators keep you warm and buoyant, so you can focus on the beauty around you rather than the chill.
Pro Tips for Snorkeling Silfra
Book in Advance: Spots fill up quickly, especially during peak travel seasons.
Dress Warm: Layers are key! You’ll wear a thermal base layer under your dry suit, so opt for wool or other insulating fabrics.
Bring a Waterproof Camera: You’ll want to capture the mesmerizing underwater views.
Don’t Skip the Sip: Silfra’s water is naturally filtered through lava rock for decades, making it some of the purest and tastiest water you’ll ever drink!
