Urriðafoss is a powerful waterfall located in South Iceland, between Selfoss and Hella. Despite not being super tall, it packs a punch with a massive water flow of 360 m³ per second, making it one of the most powerful waterfalls in Europe. It's a popular spot for salmon fishing in the summer, so you might even catch some anglers trying their luck. Plus, it's conveniently located just off Route 1, so it's an easy stop on your Icelandic road trip adventure!
