Hellisheiði
The mountain road (Route 917) between Vopnafjörður and Egilsstaðir crosses over Hellisheiði plateau leading to ear-popping and vertigo-inducing heights before descending down the other side. From here you can see superb panoramic views of Héraðsflói Bay and the black sands of Héraðssandur. Route 917 is usually closed during the winter; you can check its status before setting off on the website www.road.is.
