Lóndrangar Cliffs

The Lóndrangar are a pair of rock pinnacles in Iceland. They are volcanic plugs of basalt, that have been hewn out from softer surrounding rock by erosion. At 75 and 61 m tall, they are a singular sight, rising above and outside the ocean front due east across from Malarrif and some 10 km from Hellnar, on the southern coast of Snæfellsnes peninsula. History has it that the taller of the cliffs was ascended in 1735, while the smaller one was not climbed until 1938.The Lóndrangar are remnants from a bigger crater which has mostly eroded away.
