Vallhólmur

Vallhólmur, also called Hólmurinn, is a flatland area in the middle of Skagafjörður, Iceland, formed from sediment from the Héraðsvötn river—it is in fact an old seabed. The area's eastern boundary is the Héraðsvötn and Húseyjarkvísl, and its western is Vindheimamelar. Vallhólmur becomes the Eylendið plain to the north, but the name "Eylendið" sometimes encompasses both areas.

The region is flat and level except for two hills that rise up from the plain, Skiphóll and Vallholt. There are two farms with the same name, Syðra- and Ytra-Vallholt (South- and Far Vallholt), up against the back of Vallholt, and a short distance from Vallalaug spring, which is often mentioned in the Sturlunga saga and other sources from that era. Other farms in Vallhólmur are Vellir and Langamýri. A few of the farms in eastern Vallhólmur, which are now abandoned, belonged to Akrahreppur. This suggests that the Héraðsvötn previously ran further west, at least intermittently.

Vallhólmur is grassy and a grass pellet plant operated there for years, but it has since ceased operations. Vallhólmur also has what is considered an excellent racetrack.
