Krýsuvikurberg, often referred to as the Krýsuvík Cliff, is a striking geological feature located on the Reykjanes Peninsula in southwestern Iceland. This cliff is notable for its dramatic vertical cliffs that tower over the surrounding landscape, offering breathtaking views of the Atlantic Ocean and the rugged coastal terrain.

The Krýsuvík area is geologically active, characterized by volcanic activity, hot springs, and unique geothermal features. The cliffs themselves are composed of layers of volcanic rock, shaped by centuries of erosion and the forces of nature. The area is rich in biodiversity, with various bird species nesting along the cliffs.
