Hnausapollur, sometimes called Bláhylur is a maar located in the Iceland Highlands. It was formed when lava contacted groundwater during an eruption in 871 that spread ash over almost the entire island. The crater holds a stunning turquoise lake that is surrounded by vegetated brims and plenty of greenery - creating a beautiful sight for adventurers and landscape photographers alike.

With such striking visuals that are unique to Iceland, it is often visited by tourists from all around the world.
