All the details about your upcoming adventure in one place
Silfra is a rift formed by the separation of the North American and Eurasian tectonic plates within Thingvellir National Park. Filled with glacial water that has been filtered through underground lava rocks for 30 to 100 years, the fissure offers the clearest water on Earth with visibility exceeding 100 meters. This once-in-a-lifetime experience allows you to literally float between two continents in water so pure you can drink it. Most tours provide high-quality thermal drysuits to keep you warm and dry in the 2°C-4°C (35°F-39°F) water, ensuring a comfortable adventure year-round.
We partner exclusively with top-tier operators like Viator to ensure every tour meets strict safety and quality standards.
Access real feedback from thousands of travelers who have already braved the glacial waters of Silfra.
Secure your spot in minutes with real-time availability and immediate digital ticket delivery.
We help you compare various packages—from self-drive options to full-day Golden Circle combos—to find the best value.
Every tour we feature is led by certified PADI Divemasters or Instructors with specialized Silfra training.

Real experiences from real travelers
I've dived all over the world, but Silfra is something else. The water is so clear it feels like flying. Our guide from the Viator-partnered operator was professional and kept us warm with hot cocoa after!
The drysuit kept me completely dry and warm despite the freezing water. Seeing the tectonic plates move apart under me was a spiritual experience. Highly recommend the 'free photos' options!
It is a bit of a walk in the gear, but once you are in the water, you forget everything. The blue color of the water is unlike anything I've ever seen. Great booking process through this site.
Was worried about the cold, but the equipment is top-notch. Floating between America and Europe is a bucket list item checked! Very well organized tour.
Our guide was very attentive. We booked the self-drive option and meeting at Thingvellir was easy. The photos included in our package were professional quality.
The water is literally drinkable! It was the most peaceful experience, just floating and watching the light play on the rocks. Absolutely worth the price.
Make sure you bring thick wool socks! My feet were the only cold part. Otherwise, a 10/10 experience. The booking platform made it easy to compare.
Thingvellir is beautiful, but being inside the fissure is another level. The visibility is exactly as advertised—limitless.
Everything you need to know for your journey
No, you do not need any diving certification for snorkeling. However, you must be a proficient swimmer and comfortable in open water.
Yes, the water remains a constant 2°C to 4°C (35°F-39°F) year-round. It is glacial water from the Langjökull glacier.
Ideally, no. Drysuits are designed to keep water out. However, your face and hands will get wet as they are covered by neoprene hoods and gloves which allow a small amount of water in that warms up against your skin.
No, glasses will break the seal of the mask and cause it to leak. We recommend wearing contact lenses or bringing your own prescription mask.
Yes, most operators require participants to be at least 12 to 14 years old. There is also usually a maximum age of 65 unless a medical waiver is signed.
The actual time spent floating in the water is typically between 30 and 45 minutes, which is more than enough to see the four main sections of the fissure.
Yes, you can bring your own action camera, but it must have a wrist strap. Head mounts are not recommended as they can interfere with the mask strap.
