... Just helpful roadside markers! Hrafnseyrarheiði is the mountain pass situated between Dýrafjörður and Arnarfjörður, running from Dynjandi to Þingeyri. This road was one of the most challenging ones we faced in Iceland. It is gravel and has high exposed switchbacks with no barriers. Quite vertiginous. It is closed in winter, cutting off the southwestern part of the West Fjords from the main town of Isafjördur in the north.
