Silfra Fissure

Thingvellir National Park, Silfra, Iceland

The Basics

Many visitors see the Silfra fissure during trips to Thingvellir National Park. To truly appreciate the fissure, it’s best to go diving or snorkeling in the transparent water, which is lined with volcanic rocks.

Only PADI-qualified divers with dry-suit certification can dive in the fissure, but snorkeling is available to all travelers, even those with no prior experience. Guided snorkeling tours of the fissure typically depart from Reykjavik. Some organized tours include other activities, such as spelunking in Gjábakkahellir or Leiðarendi lava caves. Other tours make stops along the Golden Circle at sights including Haukadalur, a geothermal valley home to Gullfoss waterfall and the great geyser and nearby Strokkur.

Great experience with our instructor Chico, from Portugal! Caring, attentive, calm and secure, made this activity into a great fun and unforgettable experience for us! We didn't even felt the cold water (the drysuits really work!) L. Would totally do this again with this company.

I Had an unusual experience, but I would still highly recommend this tour to my friends and family. I am short 5' and heavy (but under the weight limit) The suit did not fit me properly due to my height. The tour guides were amazing and did all they could to help me. I am glad I tried it, even though I was not able to swim with my group.

My friend and I did the wetsuit, and while it was cold, it was totally worth it! Our guide / leader Rob was great and made us all feel really comfortable. The pictures were awesome, and the hot chocolate afterward was a nice way to warm up. FYI there’s no changing room (though there is a bathroom with a sign on it saying that it’s not a changing room), and while they provide a big, warm parka, they don’t provide towels (which was in the description, but it’s worth noting).

When to Get There

Because the water that feeds Silfra travels underground, it maintains a constant temperature and doesn’t freeze over. For this reason, snorkeling and diving tours are available year-round. Silfra is busier in summer; get there early in the day when crowds are thinner.

The Underwater World at Silfra

The Silfra fissure isn’t home to a multitude of marine life—most fish prefer the warmer waters of Thingvellir lake—but it is a breeding ground for many different types of algae. It also boasts some of the clearest waters in the world, with the natural purification process ensuring divers enjoy visibility exceeding 328 feet (100 meters).
