Þjórsá river
Þjórsá is the longest river in Iceland, 230 km, with a catchment area of 8000 km². Þjórsá is a glacier river, and its source is the Hofsjökull glacier. On its way to the sea, it falls off some cliffs in many places, forming beautiful waterfalls. Some of these waterfalls are well-known, but others are unknown pearls to discover, especially those in the highlands. The waterfall Þjófafoss in Þjórsá, south of the hill Búrfell, is well known and easy to reach.
In winter, the river can gather vast quantities of ice that has settled at its bottom. In spring, when the ice melts in Þjórsá canyons below Urriðafoss waterfall, the river breaks through the ice, which is a magnificent sight to behold.
