Join this wetsuit snorkelling tour in Silfra fissure at the UNESCO World Heritage Site, Thingvellir National Park. It's an out of this world adventure inside a hidden natural wonder, where the 100 m (almost 330 ft) underwater visibility and bright colours make for an unbelievable afternoon.
The pristine water in Silfra is one of the purest and clearest streams you’ll find on the planet, which is why it is named Silfra (silver)! When snorkelling in Silfra, you are travelling between two continents, ending the tour in a lagoon often called "the real Blue Lagoon" because of the bright blue colour of the water.
Silfra is one of the most highly regarded diving locations on earth for all these reasons and more. Located on the Mid-Atlantic Ridge, it is one of the largest fissures on Lake Þingvallavatn, a result of the endless tension of the earth as pressure builds and earthquakes tear the landscape, widening into fissures and underwater caves.
Snorkelling in Silfra rift where you are guided into this magnificent scenery is a treat for all nature lovers and adventure seeking individuals and groups.
Because it is a wetsuit tour, you'll have more freedom of movement and will even be able to free dive by holding your breath. The wetsuits you will use are 6 mm in thickness and isolate the body well from the cold water.
The water temperature is between 2–4 °C (36–39 °F). However, when wearing a wetsuit, water always gets underneath the suit, which slowly warms up. You'll need to bring a bathing suit to wear underneath the wetsuit. Thick or wool socks can help to keep your feet warm even whilst wet!
In short, you'll be able to dive deeper, but you'll be exposed to colder temperatures. If you think the water might be too cold for you, try Adventure Viking's drysuit tour, which provides the same beautiful scenery while keeping you much warmer.
So don't miss your chance to see the beautiful underwater world of Silfra fissure! Check availability by choosing a date.
