Hengifoss
This waterfall plunges 128 meters (420 feet) over a sheer drop into a glorious gorge with an unusual striped appearance, thanks to its red clay and black basalt. The 2½ km (1½ miles) path from the car park (off Route 931) leads to the falls and takes around 40 to 60 minutes, with some relatively steep sections. The superb Litlanesfoss waterfall can be found halfway up the trail.
