Hafragilsfoss is another one of the major waterfalls on the glacial river Jökulsá á Fjöllum as it thunderously drops 27m. This was the waterfall just downstream from the mighty Dettifoss within the depths of the Jökulságljúfur canyon.
Like the other major waterfalls further upstream, it's possible to experience it from both sides of the river. However, we only witnessed this falls from the more accessible east side, and even then the view was distant making me wish I had a telephoto lens at the time.
On the west side, I had read that it was a bit of an adventure to get to the falls involving rope ladders and steep climbs. The benefit is said to be closer looks at the falls, but since we didn't do it, we can't really say for sure what it was like there.
In addition to the distant views of the falls from the east bank, we also got a good vantage of the canyon carved out by the Jökulsá á Fjöllum as we looked further downstream. It kind of put into perspective the forces at work here.
Directions: From the turnoff leading to the east bank car park for Dettifoss, continue north on Route 864 for another 2km where there's another signposted turnoff to the left. Take that turnoff and continue to the car park.
If you're interested in checking out the west bank of this waterfall, there's a turnoff branching off the spur road leading to Dettifoss. See that page for details.
