Hálsanefshellir cave

Cliff Sea cave and coastal cliff formation in Iceland

At the Dyrhólaey-Vík coastline, Hálsanefshellir cave sits by black-sand shores and basalt columns; visitors photograph sea arches, watch Atlantic surf and explore nearby coastal cliffs.

Hálsanefshellir is a coastal sea cave on Iceland’s south coast, located near the Dyrhólaey peninsula and adjacent black-sand beaches. The cave is formed in columnar basalt and is visited for its striking geology and coastal views.

The cave sits beside basalt columns and cliffs typical of the area and is approached from the beach; visitors commonly photograph the columnar patterns and the cave mouth from the shoreline. Access is subject to sea and tide conditions and the cave is not a developed show cave.

The feature was formed by wave erosion cutting into Pleistocene lava flows, producing the cave opening and exposed columnar structures. There is no human construction associated with the cave itself.

The cave lies on Iceland’s south coast near Dyrhólaey and the Reynisfjara area, reachable from the main ring road and commonly visited on day trips from the village of Vík í Mýrdal.

Safety: Strong sneaker waves and rapidly changing tides make areas near the cave mouth hazardous; keep a safe distance from the waterline and check local tide conditions before approaching.
Best viewing conditions: Best viewed from the beach at low tide and in calm sea conditions for unobstructed photography and safer access along the shoreline.
