Gljúfrafoss or Gljúfrabúi ("one who lives in the canyon") is a small waterfall north of the larger falls of Seljalandsfoss in Iceland. The falls are partially obscured by the cliff rock, but hikers can follow a trail to enter the narrow canyon where the water plummets to a small pool. There is also a winding trail nearby and a wooden staircase to enable sightseers to climb roughly halfway up and view the falls from another perspective.
