Gluggafoss (Icelandic pronunciation: ​[ˈklʏkːaˌfɔsː]) is a waterfall in southern Iceland, specifically in the Fljótshlíð area. As the most prominent member of a series of waterfalls running from the river Merkjá [ˈmɛr̥cauː], it is also known as Merkjárfoss [ˈmɛr̥caurˌfɔsː]; both names are acknowledged on an on-site signpost. The waterfall is accessible off Route 261, some 17.3 km from the closest major town, Hvolsvöllur (which in turn is 106 km east of Reykjavík).

Gluggafoss has a total height of approximately 52 m and features two main drops: one for 44 m into a narrow recess, then another for a further 8.5 m (in three main channels).[1] The cliff supporting Gluggafoss has an upper palagonite (or tuff rock) portion and a lower basalt portion.[2] Distinctive of Gluggafoss' geology are the holes and tunnels formed by the river through the soft palagonite. Known in Icelandic as gluggar, or 'windows',[3] these holes allow observers at the base of the waterfall to see partly obscured water flow. According to the on-site signpost, the upper half of the waterfall could be seen only through three such vertically arranged holes prior to 1947. Hekla, due roughly 30 km north-northeast, erupted in that year, filling the river Merkjá and the tunnels of Gluggafoss with volcanic ash; this severely diminished the waterfall's exterior visibility for decades. By the present day, however, erosion has undone the blockages.[2]

Small trails on the adjacent hills allow visitors to see both drops of the waterfall up close, and also to obtain a view from above. Seljalandsfoss is another waterfall nearby and of similar (or larger) size.
