Kollafjarðarheiði

A mountain-pass F-road that's the sole crossing route through this part of the region, connecting areas that otherwise require a long detour.

Steep and narrow in sections. Because it's the only crossing route, expect it to matter more for local travel than for sightseeing.

As the only road across this stretch, it saves a long detour when conditions allow — but the steep switchbacks mean 'shortcut' doesn't mean 'easy.'

Only small stream crossings are noted — the climb and the narrow switchbacks are the actual challenge here, not water. Weather changes quickly on this pass, so check conditions immediately before driving rather than the night before.
