The land surrounding Gullfoss  is about 200 metres above sea level.  Vegetation is typical of Icelandic heathland and many of its characteristic forms are visible here outside the windows.  Lichens grow on the rocks, forming irregular patches of varying colours.  Wooly willows are widespread in the dry moorland and are easily recognised by their light green leaves covered with grey fuzz.  Other common small shrubs are blueberry and dwarf birch.  Lady smock is found in the marshy, low-lying areas.  Those with a keen eye for different types of plants will see holy grass along the edges of the paths.  In former times holy grass was picked to line chests and drawers as it gave a fine scent to clothes and linens.
