Hraunfossar, or the ‘Lava Falls,’ is one of Iceland’s most extraordinary natural wonders. Spanning nearly 900 meters, this series of waterfalls doesn’t fall from a visible river above. Instead, cold glacial meltwater from beneath the porous Hallmundarhraun lava field emerges through the rock, creating a delicate ‘lace curtain’ of turquoise rivulets. The contrast between the crystal-clear water, the dark volcanic rock, and the vibrant moss makes Hraunfossar a masterpiece of color and texture. It is a serene, ethereal landscape that showcases the hidden plumbing of Iceland’s volcanic heart.
Hraunfossar impresses with its delicate cascade of rivulets flowing out of a vast lava field, creating a lace-like natural curtain of water over black volcanic rock, surrounded by vibrant moss and greenery.
The waterfall is about a two-hour drive from Reykjavík via the Ring Road (Route 1) and Route 50/518, with a parking area and accessible paths leading to viewpoints of the falls.
Parking is free.
Hraunfossar attracts a moderate number of visitors but is less crowded than popular south coast waterfalls. The close presence of Barnafoss offers visitors a chance to explore two distinct falls in one visit, spreading out foot traffic.
