Access and Information
The natural monument is located southeast of Mývatn, north of Bláfjall. Access is via a track that is passable only to four-wheel-drive vehicles during the summer months.
A marked hiking trail leads into Seljahjallagil, approximately 5 km in length with an elevation gain of around 100 metres.
Rangers in the Mývatn area are responsible for monitoring the site.
Protection Status
Seljahjallagil, Bláhvammur, Þrengslaborgir, and the surrounding area in the former municipality of Skútustaðahreppur were designated a natural monument in 2012. The protected area covers 1,880.7 hectares.
The objective of the protection designation is to preserve the area’s distinctive geological formations, while recognising its significant educational and recreational value. The natural monument also partly serves to protect habitat for the gyrfalcon in the Mývatn region.
