A very beautifully shaped volcanic crater. It is oval, 200 m long and 50 m in depth. Two eruptions have occurred there, the latter most likely during the Settlement Age.

The natural monument covers an area of 125 ha.


Eldborg is in the middle of the Eldborgarhraun lava field in Hnappadalur, 38 km north of Borgarnes. A hiking trail runs from Snorrastaðir through the scrub-grown lava, 3.4 km. There are tourist services in Snorrastaðir, with a parking lot and toilet facilities. The area is open year-round, but access can be difficult with heavy snow and so caution should be exercised. The area is managed by the Environment Agency of Iceland; there is year-round land protection by Eldborg.
