Dive into this drysuit snorkelling tour of Silfra fissure in Þingvellir National Park, a UNESCO World Heritage Site. Conducted at the edge of Þingvallavatn, the largest natural lake in Iceland, this tour is sure to enthral and mesmerise you!
You'll have an unforgettable view down into the depths below, thanks to the silvery water which gives Silfra its name. The water is so clear, you'll be able to see as far as 100 m (almost 330 ft) down, to the shadowy caves that are formed by centuries of earthquakes widening the fissure and releasing the pressures of the earth's crust.
It's the only place on earth where you can swim between a meeting place of worlds: the North American and Eurasian tectonic plates. Witness the strength and power of the land as you drift on the current. Plants resembling troll hair grow on the rocks, floating in the water, and you'll see many shades of green and yellow algae.
Silfra was recently ranked #15 on the World's Best Dive Sites, chosen by CNN News. With this tour, you can experience the mysteries below without being a fully qualified diver, and make a fun afternoon of it while you enjoy the national park. There are also several walking trails around Silfra if you'll like to enjoy the scenery by the water.
Because you're wearing a drysuit, you'll view Silfra from the surface while the slow current carries you through a stunning underwater landscape. You stay dry underneath the drysuit, and you'll be warmer in the water, which is usually around 2–4 °C (36–39 °F).
It's so cold because it is meltwater from Langjökull glacier, filtered through porous lava rock for as much as 100 years before finally flowing into the fissure at the height of purity. Go ahead, take a sip!
Don't miss your chance for a refreshing dip in the purest water on earth! Check availability by choosing a date.
