Haifoss waterfall, Iceland Key Ring

Háifoss, or the 'High Waterfall', is a waterfall in Fossárdalur valley, innermost of Þjórsárdalur valley, in south Iceland. It is the country’s third tallest falls. Háifoss is 122 metres (400 feet) tall, meaning the only waterfalls larger than it in the country are Morsárfoss (240 metres, or 787 feet) and Glymur (198 metres, or 650 feet). It is fed by the river Fossá, which feeds into the longest river in Iceland, the Þjorsá.
