Grábrók Walk

West

Grábrók is the largest of three craters formed by the same fissure eruption roughly 3,400 years ago, and among the easiest volcanic craters to climb in Iceland. From the parking area right off Route 1, a well-maintained trail with several hundred wooden steps reaches the rim in about 15 to 20 minutes. At the top you can walk the full circumference and look into the red-and-black cinder bowl, which has stayed remarkably intact. The other two craters — Grábrókarfell and Litla-Grábrók — are visible nearby. The lava field covers around 7 square kilometers, now softened by birch scrub and thick moss. The crater sits just east of Lake Hreðavatn, near Bifröst University, about 170 km north of Reykjavík — a natural stopping point when driving the Ring Road. On clear days the views from the rim take in the Borgarfjörður valley. The whole area has been a nature reserve since 1962. The climb suits most fitness levels, including families with older children. The path can ice up in winter, so traction devices help from November through March. Parking and access are free.
