Welcome to Western Þjórsárdalur
The powerful Þjórsá is Iceland’s longest river, a fast-flowing, churning mass of milky glacial water that courses 230km from Vatnajökull down to the Atlantic. Including its tributaries, it accounts for almost one-third of Iceland’s hydroelectric power. Rte 32 follows the western side of the river, and as it moves upstream and into the highlands you'll traverse broad plains, split by the enormous river, that lead to volcanic fields and finally the foothills of the mountains beyond. It is a relatively untouristed area, with Viking ruins, hidden waterfalls and prehistoric-like river landscapes.
