A small waterfall north of the larger falls of Seljalandsfoss in Iceland. It is less visible in the main one.

This waterfall is absolutely epic. It's a cool spot. It's about an hour outside of Reykjavik and I don’t think anything can adequately prepare you for just how majestic it is. If it’s colder outside, definitely layer up and wear some waterproof clothing, otherwise you will get soaked.
