Gluggafoss takes its name from the natural “windows” or holes formed in the rock, where the water flows through the cliff face, creating a unique and visually striking waterfall. This feature sets it apart from many other waterfalls in the region.

The surrounding landscape of Fljótshlíð is green and peaceful, and the waterfall is easily accessible via a short walk from the road. Gluggafoss is a popular stop for visitors and photographers seeking a tranquil yet unusual waterfall experience in South Iceland.

Geology

Gluggafoss, also known as Merkjárfoss, lies in the Merkjá river. The upper cliff consists of palagonite or tuff while the lower ledge is basalt. The river has carved tunnels and grooves into the softer rock, forming the distinctive windows that give the waterfall its name.
