Scuba Diving and Snorkelling in Silfra fissure

Two people scuba diving in Silfra Fissure

Nested in the heart of Iceland’s unique landscape, more specifically in Þingvellir National Park, is Silfra fissure. Þingvellir National Park is a remarkable sight on its own as it has a rich history and is a UNESCO World Heritage site. Further, the national park’s area is divided between two continents, North America and Eurasia, letting visitors check two continents off the list. Scuba diving and snorkelling in Silfra fissure has become a popular tourist activity, where visitors can swim between the two continents. 

 

How did Silfra fissure form?

The rift of the Silfra fissure was formed in 1789 when earthquakes accompanied the movement of the tectonic plates, forming a crack between the two. As the ice from Langijökull glacier melts during the summertime, it flows down towards Silfra and gets filtered through the lava field on the way. By the time the water from Langijökull glacier reaches Silfra, it has been travelling for about 70-100 years. The fissure only keeps getting bigger and better, as it grows about 2 cm each year with the tectonic plates drifting apart.

Plunging into the crystal clear water of Silfra

In addition to being able to easily walk between two continents, it is also possible to swim between the two. Silfra has become a mecca for scuba diving and snorkelling enthusiasts around the globe and is an extraordinary experience unlike any other. Visitors can choose to either dive or snorkel in the fissure, which is possible during both winter and summer. 

Taking a dive into the crystal-clear glacial water of Silfra, divers and snorkelers can expect to see captivating underwater landscapes with visibility exceeding 100 metres [328ft].

 

Snorkelling in Silfra 

Snorkelling between the two tectonic plates is a unique, once-in-a-lifetime experience.  Anyone above the age of 12 can participate and therefore there is no need to have any sort of certifications. The only thing needed is to fill out a medical form online before arrival. 

Clad in drysuits to make the experience less chilly, snorkelers float effortlessly on the water’s surface, taking in the breathtaking underwater world beneath. The slow glide through the Silfra Fissure allows participants to enjoy the sight of the colourful underwater landscape, marine life, and geological formations. Snorkelers can even drink the water as it is filtered through lava field capillaries, making it a refreshing drink at around 2°C – 4°C [25-35°F] year-round.
