Kjalvegur, (“Keel road”) the south section, 88,2 km from the service centre by Gullfoss to the junction to Hveravellir. From there and north to road 731 are 79 km. This route is passible for all vehicles. Kjalvegur has always been a much–used mountain route between the north and south of Iceland, being easily accessible from Húnavatnssýsla, Skagafjörður and Eyjafjörður. The many grassy areas made this route easier than other inland tracks when people travelled on horseback. The oldest track was through the centre of Kjölur, on the east of Kjalfell, but after the incident at Beinahóll in 1780 people mostly used the western route through Þjófadalir.
