Silfra is a unique fissure located within
Þingvellir National Park,
situated between the North American and Eurasian tectonic plates.
The fissure is part of the Þingvellir rift system and is filled with
crystal-clear glacial water that filters through porous lava rock
from
Þingvallavatn.
Visibility in the water can reach up to 100 meters under ideal
conditions.
Silfra is world-famous for snorkeling and diving and is considered
one of the top freshwater diving sites in the world.
Water temperatures remain cold year-round, typically between 2–4°C,
creating a challenging yet unforgettable experience.
Visitors have the rare opportunity to swim between two continental
plates in a truly extraordinary natural setting.
The fissure lies close to
Almannagjá
and
Hrafnagjá,
two of the most prominent rifts in the Þingvellir area.
In addition to water-based activities, the surrounding landscape is
ideal for walking and exploring the geology and history of the
national park.
Access to Silfra is regulated by Þingvellir National Park, and all
snorkeling and diving must be conducted with licensed operators and
certified guides.
Visitors staying longer in the area can stop by the
Þingvellir Visitor Center
for information about regulations, geology, and conservation, or make
use of the nearby
Þingvellir camping site.
Silfra uniquely combines geology, adventure, and pristine nature and
offers an unforgettable way to experience Þingvellir from a
completely different perspective.
