4-Hour Nighttime Freedive at Silfra Fissure with Experienced Guides

Swim through the clear water of Silfra Fissure in Thingvellir National Park on this nighttime freediving tour. The tour suits both experienced freedivers and newcomers to the sport, and you see Silfra Fissure under the night sky.

Depending on your pickup option, you are either transferred from your accommodation in Reykjavik to Thingvellir National Park, or you meet your freediving guides at the Silfra parking lot. There, you meet the rest of your group and get a briefing on the activity ahead.

Your guide explains everything from how to use the equipment to the origins of the glacial water in Silfra Fissure. Your guide also teaches you the correct breathing techniques, so you can stay underwater for longer and explore more of the fissure.

To keep you warm, you wear a wetsuit with a neoprene hood and gloves. You also learn how to use your mask, snorkel, and fins correctly, and you get a torch to find your way through the fissure in the dark.

In the water, visibility reaches about 328 feet (100 meters), and you see the dark shades of blue, the submerged canyons, and the bright green algae known as "troll hair." The deep sections of the fissure give you room to practice your freediving skills.
