Gerðuberg is a stunning natural geological formation consisting of a long row of perfectly shaped hexagonal basalt columns stretching along a cliff on the southern side of the Snæfellsnes Peninsula in western Iceland.
These basalt columns, reaching between 7 and 14 meters (23 to 46 feet) in height and up to 1.5 meters (5 feet) wide, form an impressive wall-like structure often compared to a man-made fortress. The symmetrical and geometric shapes of the columns make Gerðuberg one of Iceland’s most striking and rare geological wonders.
The cliffs were formed thousands of years ago during volcanic eruptions when rivers of basaltic lava cooled rapidly against the sea, creating these unique pillar shapes through a natural process called columnar jointing.
The cliff is located just off Highway 54, approximately 115 kilometers from Reykjavík and 46 kilometers north of the town of Borgarnes.
Good to know
Scenic beauty
While Gerðuberg’s hexagonal columns are an impressive geological spectacle and offer excellent photo opportunities, the location is best appreciated if you are already in the area. It is visually striking but not necessarily a must-see standalone attraction. Visitors often consider it a memorable part of a larger Snæfellsnes Peninsula tour including other natural highlights.
Accessibility
Gerðuberg is easily accessible by car from Reykjavík, situated just off Highway 54 along the peninsula’s southern coast. However, to reach the base of the cliffs, visitors must drive a short gravel road which is bumpy and unpaved, requiring some caution. The terrain near the cliffs is uneven with a steep incline to approach the formations.
Cost
There is no entrance fee or parking charge at Gerðuberg, making it a free natural attraction for all travelers.
Crowd level
Gerðuberg is generally not crowded. Due to its location slightly off the most popular routes and the nature of the terrain, visitors typically find it peaceful with plenty of space to explore and photograph. Early visits or later in the day provide even quieter conditions.
