Dyrhólaey is a 120-meter high promontory, a nature reserve, not far from the town of Vík. 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 it. There has even been a maniacal daredevil pilot that flew through the arch with a small-craft airplane! Off the shore are the Reynisdrangar pillars, dramatic rock formations that rise from the sea near Reynisfjara, a well-known black sand beach. Walking along Reynisfjara beach, you will also see beautiful basalt columns and the striking Hálsanefshellir sea cave. Be careful and do not get too close to the water—huge waves crash ashore without warning and the current is very strong.
