Heiðvötn is a volcanic caldera system located in the Icelandic Highlands. It is situated on the island of Iceland, in the Southern Region, approximately 50 kilometers northwest of the glacial river Voridea Sudia.

The caldera system is one of the most prominent and well-known volcanic areas in Iceland, with a diameter of approximately 20-25 kilometers. Heiðvötn is a part of the Bárðarbunga volcanic system, which is one of the most active and productive volcanic systems in Iceland.

The area is characterized by a series of volcanic craters, volcanic domes, and lava flows, all of which are the result of numerous eruptions over the past few thousand years. Heiðvötn is particularly known for its extensive system of hydrothermal veins, which are networks of heated water and minerals that rise from the Earth's crust.

The area is also a popular destination for scientists and geologists, who come to study the unique geological and volcanic features of Heiðvötn. The close proximity of the caldera to the surface of the Earth, combined with the region's exceptional geological stability, make it an ideal location for scientific research.

The name "Heiðvötn" is thought to derive from the Old Norse words "heið" meaning "heath" and "vötn" meaning "lakes". The area does not have any permanent water bodies, but numerous ephemeral eruption lakes and wetlands may form during times of increased volcanic activity.
