Hraunfossar

Unlike any other waterfall in Iceland. Water seeps through a lava field and emerges as hundreds of small rivulets pouring into the turquoise Hvítá river. Stretches for nearly a kilometer.

It's mesmerizing. Hundreds of streams trickling from under the lava, each one catching light differently. The water is impossibly blue. It's quiet, gentle — the opposite of power waterfalls.

The water comes from Langjökull glacier, filtering through the porous Hallmundarhraun lava field for miles underground before emerging here. The lava flowed from a crater 1,500 years ago.

Right next to Barnafoss — do both. Easy access, parking lot nearby. The autumn colors here are incredible. Less crowded than south coast falls. Good cafe at the visitor center.
