Landbrotshólar are many clusters of pseudocraters, formed in the Eldgjá eruption in 934 to 940 when lava flowed over wetlands. Pseudocraters are formed when hot magma comes into direct contact with water-soaked substrates and causes the water to instantly boil. Magma flows through lava tubes, but where the magma bursts from the lava tubes, lava nuggets are formed. This chain reaction goes on until the lava has worked its way over the wetland and built up a cluster of pseudocraters.

QUICK NOTES:

• What it is: A field of pseudocraters in south Iceland. If you're interested in geology then this is a place for you!

• Best season: Any.

• Best time of day: Any but sunrise and sunset for the most contrast.

• Nice to know: This is a big area but you can see a few of them from the road. There is also a 9 km hiking trail around Landbrotshólar and starts at the bridge over Skaftá.
