Gatklettur sea arch at Arnarstapi Cliffs on the Snæfellsnes Peninsula, West Iceland — a dramatic basalt rock arch carved by North Atlantic waves.
Gatklettur Arch is a natural basalt sea arch located near Arnarstapi on the Snæfellsnes Peninsula. The formation spans a narrow opening above the Atlantic, shaped by sustained coastal erosion. Its curved aperture creates a defined framing element within a horizontal shoreline composition.

Best Light
Light works best when low-angle sun strikes across the arch because angled illumination enhances rock texture and increases separation between the opening and surrounding sea.
Why This Light
Season
Year-Round Stable
In summer, extended daylight enhances detail within the rock texture and surrounding coastline. In winter, stronger swells and lower sun angles increase contrast between the arch and open water.
Crowds
Busy Midday
Restrictions
Cliff-edge exposure and wind conditions may affect safe positioning near the viewpoint.
