Bláhylur - also known as Hnausapollur - is a breathtaking crater lake nestled in the Icelandic Highlands. Created from a massive eruption in 871 (just before Iceland’s first settlers allegedly arrived), the lake is famous for its deep blue colour. It's located right by the F208 highlands road where you can do a tiny detour and get some great views over the lake.

QUICK NOTES:

• What it is: A beautiful lake in the highlands.

• Best season: Summer.

• Best time of day: Any (but sunrise and sunset for the best light).

• Nice to know: You'll need a capable 4x4 to reach this spot. To get an overview like in the image you need a drone.
