The road of Kaldidalur valley is a highland road, stretching from Thingvellir to Husafell (in Borgarfjordur district), between Langjokull glacier and Ok shield volcano. It is Iceland's second-highest pass.
The Kaldidalur road was a common horse route in former times but was made available for cars around 1930, though only passable for a few months of summer. One can continue to the north through the barren sand area of Storisandur. South of the valley is a cairn wherein travelers would put naughty verses.
