About Gullkistugjá
Gullkistugjá is a prominent volcanic fissure located west of Helgafell above Hafnarfjörður. The fissure forms part of a long fracture system that runs through the lava fields surrounding the mountain, extending across the rugged terrain shaped by past volcanic activity. The feature is described as a “long fissure zone” that cuts through the southeastern part of Helgafell and continues southward through the lava. Nearby lies Skúlatún, a small grassy hill that stands out within the otherwise dark lava field, highlighting the contrast between volcanic and vegetated landscapes. Gullkistugjá provides a clear example of how tectonic forces and volcanic processes create cracks and fractures in Iceland’s surface. The area is relatively quiet compared to more famous geological sites, offering visitors a more secluded experience of raw Icelandic nature.
History & Background
Gullkistugjá formed as part of the volcanic and tectonic activity associated with the Reykjanes Peninsula, where the Earth’s crust is gradually stretching and fracturing. The fissure developed over time as lava flows cooled and the ground shifted, creating cracks and fracture zones across the surface. Located near Helgafell above Hafnarfjörður, it is part of a wider system of geological features that reflect Iceland’s position along the Mid-Atlantic Ridge. Although not developed as a major tourist site, Gullkistugjá remains an important natural feature that illustrates the long-term geological processes shaping the region.

Why Visit
Visit Gullkistugjá (Helgafell) to explore a dramatic volcanic fissure in a quieter setting above Hafnarfjörður, where raw lava landscapes, deep cracks, and unique features like nearby Skúlatún reveal the powerful geological forces shaping Iceland.
Did You Know?
Small green areas like Skúlatún can form in lava fields where soil and moisture accumulate over time—creating isolated patches of vegetation surrounded by bare volcanic rock.
A long volcanic fissure west of Helgafell, Gullkistugjá cuts through lava fields above Hafnarfjörður, revealing the powerful geological forces shaping the Reykjanes landscape.
West of Helgafell, the land opens into a rugged lava field marked by deep cracks and uneven terrain. Among these features, Gullkistugjá stands out as a long fissure stretching through the landscape, quietly recording the movement of the earth beneath. For generations, people crossing this area would have noticed the dramatic contrast between the dark lava and the occasional patches of green, such as nearby Skúlatún, where vegetation has taken hold. The fissure itself is not a single dramatic canyon but a system of fractures that guide the eye across the terrain, showing how the land has slowly pulled apart over time. Today, visitors who walk the paths around Helgafell encounter Gullkistugjá as part of a broader volcanic landscape—one that feels both raw and untouched, offering a glimpse into the ongoing geological processes that continue to shape Iceland.
Practical Information
Best Time
Late spring to early autumn (May–September) offers the safest and most accessible conditions, with clear paths and good visibility across the lava fields. Summer provides long daylight hours, ideal for exploring the area around Helgafell.
Duration
45–90 minutes depending on route and pace. The fissure is typically visited as part of a longer walk around Helgafell and the surrounding lava landscape.
Access
Gullkistugjá is located west of Helgafell above Hafnarfjörður and is accessible on foot via hiking routes in the surrounding lava fields. There are no formal paved paths directly to the fissure, so visitors should follow established walking trails from nearby parking areas and use caution when navigating uneven terrain.
