It's a quieter alternative to more famous caves, popular with travelers who enjoy combining hiking and tide-dependent adventures along the dramatic southern shoreline.

Grjótagjá is a small cave in the Mývatn region where a natural hot spring flows through the interior, creating warm, mineral-rich water that was once swimmable.
