The steepest mountain road or the mountain pass in Iceland on both sides, up and down, is "Helisheiði eystri". Although this mountain road is not officially part of the Ring Road, it connects the Eastern Region and the Northern Region a bit north of the main Ring Road. The drive is approximately 14 kilometers, and the highest point is about 660 meters. Even though driving the road is a bit intimidating the view from the top is astonishing.
