Really amazing waterfall hidden in a rift. As we visited in a morning of late October, the environment was slippery due to frozen mist from the waterfall. You must wear appropriate waterproof clothes to walk close through the rocks on stones in the creek. You can park at Seljalandsfoss (ISK 900, pay-and-display) as there is no parking space nearby (all possible areas are fenced or blocked around!).

After visiting the famous Seljalandsfoss you really need to check out this waterfall just a short walk away. It's a bit hidden, but the footpath leads you right to it. No need to repark your car. It's 40m in height and hidden inside a small canyon. You need to walk through a short section of shallow water (depending on how much water the fall carries at the moment). You will stay with dry feet if you're well balanced and jump from stone to stone. But it really is just a few steps. It's popular, but we went there at around 5.30pm and there weren't many visitors anymore. The fall, the spray, the views up. It's an impressive sight. There is also a winding trail nearby and a wooden staircase to enable sightseers to climb roughly halfway up and view the falls from another perspective. A really fantastic fall. The south offers many amazing attractions. And this one here is one of them - and one you shouldn't miss.

A true hidden gem next to Seljalandsfoss. No need to move your car, it is a short paved walk away! In good weather conditions you can walk over a few rocks to get closer to it. A true gem

This was by and far my favorite attraction I visited in Iceland. Gljúfrabúi (Canyon Dweller) is literally a hidden gem near the famous Seljalandfoss, and is a waterfall hidden behind a cliff that you need to traverse a short stream to get to. The narrow valley is quite dark, but it is a short distance and if the water levels are low enough, you can step on rocks and not get your shoes wet. Once you past the cliff, the valley opens up and the majestic Gljúfrabúi stands in front of you with the open sky above. The views are quite breathtaking and the hidden nature of the falls, from the entrance to the actual canyon, makes the experience absolutely unforgettable. These days, Gljúfrabúi is not quite so hidden anymore, as there was a tour group waiting outside to enter behind me when I visited. The waterfall is accessible on the trail next to Seljalanfoss on the left.

Woah, this place is incredible. You can park at seljalandsfoss, see those then follow the path for a short walk here. You will need to step across some stones and might get your feet wet, it's so worth it as you turn the corner and see the absolutely beautiful falls inside the cave. You may get a bit of spray hit you if you stand on the rock and it's slippery so be careful. This was definitely one of the best things I saw in Iceland on my trip.

After visiting Seljalandsfoss, we walked to Gljufrabui Waterfall. To see it, you have to walk through a short, narrow passage with water flowing out from a cave-like space. The cave has a hole at the top from which the water pours down, creating a very interesting sight. I liked it a lot. Since the passage is narrow and the cave area is small, it could be frustrating if there are a lot of people there.

Located just a short walk from Seljalandsfoss away from the parking area is this gem of a waterfall within a crevice. It's stepping stones to get to the waterfall itself over the stream but easy enough. My young kids (3 and 6) did not go back in the crevice. My 6-year-old probably could have made it but was too scared.

Simply the best. It's different. It's tall. It's stunning. You get really close. Walking into the cave over the stream makes it adventurous and limits the number of people so this feels less crowded. Don't miss this but DO wait your turn before entering the cave. Even the walk here from the nearby larger waterfall is beautiful.
