About place

Þjórsá is the longest river in Iceland, 230 km, and has a catchment area of 8000 km². Þjórsá is a glacier river and its source is Hofsjökull glacier. On its way to the sea it falls off some cliffs in many places and there forms beautiful waterfalls. Some of these waterfalls are well-known, but some others are unknown pearls to discover, especially those in the highlands. The waterfall Thjofafoss in Thjorsá south of the hill Búrfell is well known and easy to reach. 

In winter the river can gather up huge quantities of ice that had settled at its bottom and 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.
