Seljalandsfoss

A 60-meter waterfall you can actually walk behind. Seriously — there's a path that takes you right behind the curtain of water. Not many waterfalls in Iceland let you do that.

Standing behind 60 meters of falling water is genuinely something. The light comes through the curtain, everything's misty and loud. Best at sunset when the light turns golden.

Seljalandsfoss drops from the cliffs that used to be Iceland's coastline thousands of years ago. The Seljalandsá river feeds it from Eyjafjallajökull glacier — yeah, that volcano. The cave behind the falls was carved out over centuries by the water itself.

You WILL get wet walking behind it. Like, properly soaked. Bring a waterproof jacket or accept your fate. The path can be slippery, especially in winter — some people skip the walk-behind when it's icy. Also: don't miss Gljúfrabúi, a hidden waterfall just 5 minutes walk north. Most tourists miss it.
