Þjófafoss (pronounced as /is/, "thieves' waterfall"; also Thjofafoss) is located on the river Þjórsá on the east side of the Merkurhraun lava fields in the south of Iceland, at the southwest tip of the hill Búrfell.[1] A viewing point for the waterfall can be accessed by a gravel track that leads about 4km (02miles) northwest from Route 26 or by a track that leads south from Route 32 past the hydroelectric power station Búrfellsstöð and Hjálparfoss.
