Westfjords is an region with more fjords than the rest of the country. The region is one of two with very steep hills, the other one being East-Iceland. Roads may be closed several months a year, separating the northern towns from the southern ones. Tunnels, especially the Vestfjarðargöng tunnel, has improved that situation. The westfjords are connected to the rest of the country by a 7 km-wide isthumus between Gilsfjörður and Bitrufjörður. In the Icelandic folk tales there is an explanation for this short isthmus. In those tales, two trolls tried to separate the Westfjords from the rest of the island. They dug all night and eventually tried to hide from the sun in Kollfjarðarnes. But as the sun rose, they turned to stone. The result of their digging was the short isthmus between Gilsfjörður and Bitrufjörður.
