Dyrholaey is a 120-metre high promontory, not far from
Vik. The place got its name from the massive arch that the
sea has eroded from the headland. (The name literally means
"door-hole"). When the sea is calm, big boats can sail through
From Dyrholaey is a great view. The headland is thought
to have been made in an underwater volcanic eruption late
in the glacial period, not unlike the eruption of Surtsey.
Several outcrops are in the sea, the highest one called
Hαidrangur ("High column") is 56 m. high. Dyrholaey has
been a natural reserve since 1978.
Birdlife is abundant, with puffins and eider ducks being
the most common species in the area. The promontory is widely
known among sailors as "Portland".
