10 Most beautiful crater lakes in the world – #1 is a must see! (With Pictures)

2. Kerið Crater Lake – Iceland

The Kerið Crater Lake is located in the Grímsnes area in south Iceland, on the Golden Route. This volcanic crater lake is one of the many lakes in the Western Volcanic Zone of Iceland. But, its caldera, made of mainly red volcanic rock, is still intact and recognizable. It is about 55m deep, 170 m wide and 270 m across. Due to the minerals from the soil, its water is opaque and vividly aquamarine.
