Best Kerid Crater Day Trips & Things to Do

Nestled in Iceland’s Grímsnes region, Kerið Crater is a striking volcanic caldera formed roughly 6,500 years ago, part of the Western Volcanic Zone. With its vivid red volcanic rock walls, deep blue lake, and lush green moss in summer, Kerið offers a vivid contrast to Iceland’s often stark landscapes. Easily accessible along the Golden Circle route, it sits near Þingvellir National Park and close to Gullfoss Falls, making it a popular stop for travelers exploring geothermal wonders and tectonic drama. Unlike most calderas, Kerið is believed to be a collapsed magma chamber rather than an explosion crater, offering a unique geological story. Visitors can walk the full 55-meter-deep rim and descend via stairs to the lake edge, especially beautiful at sunset when the rock glows.
