Several mountains in Iceland go by the name Helgafell. In most instances the name derives from the Icelandic word helgur (holy, spiritual).
The Helgafell featured below is in Hafnarfjörður just outside Reykjavík, and a popular hiking destination for the local community.
From May until July the low midnight sun on the northern horizon is incident on the dome-shaped profile of the mountain. When the stars align, magic happens. (Note: the strike rate is very low and it takes many attempts to acquire something worthwhile.)
