Kerið is a beautiful volcanic crater with a lake in South Iceland. It was formed about 6,000 years ago and is known for its striking colors. The crater walls are red from iron deposits, and the lake is a bright blue-green.
The crater is approximately 55 m deep (180 ft), 170 m wide (560 ft), and 270 m across (890 ft)!
Visitors can walk around the top of the crater for great views or take a path down to the water and walk around the lake. Unlike many craters that are made by explosions, Kerid was formed when a magma chamber collapsed, giving it a unique shape.
It's part of the popular Golden Circle route, making it an easy and favorite stop for tourists.
