Gljúfrabúi Waterfall is an Icelandic hidden gem and a great addition to any adventure in South Iceland. Get ready for the perfect mix of excitement and serenity, as you can explore the spooky confines of its slot canyon while being surrounded by tall cliffs. Inside this canyon you will be submerged in swirling mist from the waterfall and icy cold stream water. After reaching the falls, head out and complete this experience with a visit to the Seljalandsfoss waterfall. With only about 3 kilometers total distance in between, visiting both sites in one morning or afternoon is an excellent way to make the most of your trip. So come prepared with waterproof clothing and shoes, because once you enter this magical place, you won’t want to leave!
