Book NowStory & Folklore
Þingvallavatn is Iceland's largest natural lake, sitting in the rift valley of Þingvellir where the North American and Eurasian tectonic plates slowly pull apart. The lake is 84 square kilometres and reaches depths of 114 metres. It contains four species of Arctic char found nowhere else on Earth — genetically isolated populations that have evolved separately in the lake over thousands of years since becoming trapped after the last Ice Age. The lake's Silfra fissure, accessible from its western shore, is one of the world's top diving and snorkelling sites, with visibility exceeding 100 metres in 2°C glacial meltwater filtered through lava for decades. The lakeshore is the start of the Golden Circle.
