There are so many spectacular waterfalls in Iceland, but there aren’t many that you can walk around and completely encircle for a 360° view. The cliff that the Seljalandsá River spills over has a wide cave that heads right behind Seljalandsfoss Waterfall making that entirely possible!
Located in the Southern Region of the country the falls are extremely popular and one of the most photographed , only a few steps from the parking lot. It is less than a quarter of a mile to complete the stunning loop. 
You’ll want to wear a rain jacket because of all the mist, which can also cause the path to become slippery so walk with care.
The waterfall is just shy of 200 feet fall and its power is a result of the melt water from the Eyjafjallajökull Glacier. That’s the one with the volcano underneath it that downed flights in Europe when it exploded in 2010. Don’t miss nearby Gljúfrabúi to double the adventure with far fewer crowds.
Just a ten minute walk away on a nicely maintained path with additional waterfalls and a stream which may have fish floating around in it.
Good to know:
+The first parking lot has a fee of 700 ISK, if you drive further down the road you can find free parking within short walking distance
Fun Fact:
+You may have seen the waterfall featured in Justin Bieber’s music video I’ll Show You or on the television show The Amazing Race
