Klougljúfur canyon is located in Víðidalur in Vestur-Húnavantssýsla. The canyon is said to be named after the female troll Kola, which is said to have dug the canyon to live there. The canyons run about 1-2 Km and are a couple of tens of meters deep. The canyon is, for the most part, unexplored and is exceptionally beautiful.
Turn off the Ring road (road Nr. 1) onto road 715 and when you get to the U turn on road 715 turn off that road onto Hrappstaðarvegur (not numbered on google maps) and continue until you get to the parking lot.
Explore the canyons but be safe out there, as there are no man-made barriers to protect you. Check out Kolufossar waterfall.
Walk over the bridge that goes over the canyon and look down the stream going down the canyon.
