Brúarfoss

Brúarfoss ('Bridge Falls') is a relatively small waterfall compared to many of its Icelandic counterparts, but its diminutive size does nothing to take away from its staggering beauty. Both locals and seasoned travellers regard Brúarfoss as one of the country’s hidden gems, often labelling it 'Iceland’s Bluest Waterfall.'

The glacial river Brúará falls 2-3m, ending in a U-turn at the base of the waterfall, where the river is concentrated into a deep crevice that runs through the centre of dark volcanic rock formations. This creates sky-blue rapids that almost defy the imagination—and the vistas are made all the more beautiful by the surrounding, lush green flora, which provides a stark contrast to the flowing water.  --- Guide to Iceland
