What will you see and do?

Silfra Fissure's unique body of water was formed in 1789 after a giant earthquake caused the North American and Eurasian tectonic plates to crack and separate. Since the 18th century, the plates have drifted apart at a rate of approximately 2.5 centimeters a year.

By carving out this rift, Silfra Fissure has created an incredible environment that allows snorkelers and divers to swim between two continents. The depth of Silfra Fissure ranges from 40 to 100 meters, while its clarity provides visibility of up to 100 meters.

While snorkelers can marvel at the natural wonder from above, those with a scuba diving certification can descend 60 meters below the surface to touch the once-conjoined tectonic plates.

Doing so provides any nature enthusiast with a deep connection to the earth and the humbling feeling of witnessing the site of a crucial part of the planet's history.

Silfra Fissure's rare combination of salty surface water and pure underground glacial water creates an unmistakable blue hue that surrounds divers beneath the lake's surface.

While the site is the most popular with adventure-seekers and diving enthusiasts, scientists also use the rift to research continental drift and climate change.

While the waters of the fissure are too cold for many sea creatures to thrive, several species call this stretch of water home, including the arctic char. However, these usually reside in the depths of the lake, among the flourishing algae, rocks and boulders and so are rarely seen by visitors on a day tour to Silfra Fissure.

When is the best time to visit Silfra Fissure?

You can enjoy a day trip to Silfra Fissure at any time of the year. The rift remains open year-round and its cool waters always range from 2 to 4 degrees Celsius.

However, you may choose to visit during the spring and summer months when the land conditions are less extreme, especially if your tour includes other sites.
