Location

West Iceland

Near Bifröst, along Route 1

Grábók is a well-preserved scoria crater located alongside Route 1 in West Iceland near the village of Bifröst. Formed approximately 3,400 years ago during a volcanic eruption that also produced the extensive Grábrókarhraun lava field, this cinder cone crater stands as one of the most accessible volcanic features in Iceland. A wooden staircase with around 300 steps ascends the steep outer wall of the crater, making it easy for visitors to reach the rim and peer into the hollow interior. From the top, panoramic views stretch across the surrounding lava field, the Hraunfossar area, and the mountains of Borgarfjörður. The crater and its surrounding area have been a protected nature reserve since 1962.

Getting There

From Reykjavík, drive north on Route 1 through the Hvalfjörður tunnel (or around the fjord) and continue through Borgarfjörður.

In winter, the staircase can be icy and the crater may be dusted with snow, creating a dramatic appearance but requiring caution on the steps. The crater makes an excellent stop on any season's Ring Road drive, but allow extra time in winter for potentially slippery conditions.
