Helgrindur (Icelandic pronunciation: [ˈhɛlˌkrɪntʏr̥], also known as Lýsuskarð, Lysuhóll or Lysukard)[2][3] is a volcanic mountain range or massif in the middle of the Snæfellsnes peninsula that provides a backdrop to the port of Grundarfjörður.

The volcano can be regarded as potentially active, with a risk of lava flows and much more rarely explosive tephra eruptions.

The 2–3 km (1.2–1.9 mi) wide range,[1] is in the middle of the Snæfellsnes peninsula and thus divides the northern large bay of Breiðafjörður from the southern bay of Faxaflói.

[1] The weather systems in the two large bays are often quite different and the stormy winds across the range are quite notorious and can be heard sometimes at sea level.

In total length there is a 30 km (19 mi) fissure swarm that extends from the south-east into the sea at its north-west.
