Gljúfrabúi is one of our favourite waterfalls in Iceland. It's located right next to the famous Seljalandsfoss; however, you wouldn't know it was there unless you knew it was there!

It's tucked away inside a cave, and you have to walk through a small stream to reach it. We visited during our summer road trip to Iceland in June and absolutely loved it! Inside the cave, you will get quite wet as the spray from the waterfall will soak you! But it's worth it as it's absolutely beautiful.

If you climb up onto a rock inside the cave, you can get a pretty stunning shot as well.
