Gerðuberg Cliffs – Basalt Columns in Iceland
A perfectly symmetrical wall of hexagonal basalt columns on the Snæfellsnes peninsula

Location
West Iceland / Snæfellsnes
Along Route 54 on the Snæfellsnes peninsula
Gerðuberg is a long cliff face of remarkably regular basalt columns located on the southern edge of the Snæfellsnes peninsula in West Iceland. Stretching approximately 500 meters, the formation consists of perfectly upright dolerite columns with strikingly uniform hexagonal cross-sections. The geometric precision of these columns is considered among the finest in Iceland, formed when a thick lava flow cooled with exceptional evenness over thousands of years. Unlike many of Iceland's basalt formations that require hiking, Gerðuberg sits right beside the road, making it one of the most accessible examples of columnar jointing in the country and an ideal stop when exploring the Snæfellsnes peninsula.

Access
Roadside
Just a few minutes' walk from the parking area beside Route 54. No hiking required.
Distance from Reykjavík
~155 km
About a 2-hour drive north via Route 1 and Route 54 toward Snæfellsnes.
What to Expect
Perfect Hexagonal Geometry
The columns display some of Iceland's most regular hexagonal cross-sections, with remarkably uniform sizing and near-perfect symmetry.
Dolerite Composition
Unlike softer basalt, Gerðuberg's columns are composed of dolerite, a harder rock that has resisted erosion and preserved the sharp geometric edges.
Easy Roadside Access
No hiking is required. The cliffs are visible from the road and just a short walk from the parking area, making them accessible to all visitors.
Snæfellsnes Gateway
Located at the entrance to the Snæfellsnes peninsula, Gerðuberg makes an ideal first stop before exploring the area's other natural wonders.
Geological Education
The formation is an excellent place to understand columnar jointing, as the clear, large-scale columns illustrate the cooling process perfectly.
Quiet Atmosphere
Despite its impressive appearance, Gerðuberg sees fewer visitors than South Iceland basalt sites, offering a more peaceful experience.
Getting There
Gerðuberg is located along Route 54 on the southern side of the Snæfellsnes peninsula. From Reykjavík, drive north on Route 1 and then take Route 54 west toward Snæfellsnes. The cliffs appear on the north side of the road approximately 155 km from Reykjavík, shortly after the town of Borgarnes. A small parking area is located beside the road. The site is accessible by any vehicle type and requires no special equipment. It pairs well with a full day trip around the Snæfellsnes peninsula.
Best Time to Visit
Gerðuberg can be visited year-round since it requires no hiking and the road is maintained in all seasons. Summer offers the best light and warmest conditions for exploring the base of the columns, while winter can coat the formation in snow and ice for a different aesthetic. The roadside location means even brief stops during winter road trips are feasible. Late afternoon light in summer creates dramatic shadows that emphasize the columnar geometry. Since the site is less crowded than many basalt attractions, timing is less critical for avoiding crowds.
