Hraunfossar is a uniquely beautiful series of waterfalls located on the Hallmundarhraun lava field. This lava field was created when a volcano under the Langjokull glacier erupted shortly after the settlement of Iceland. Hraunfossar is formed as several small streams flow from the lava field into the Hvitá river. The name Hraunfossar appropriately means “Lava Falls,” it is also known as “Girdingar cascade.”
