Golden Circle

Vivid red volcanic crater lake Kerid with aquamarine water on the Golden Circle in South Iceland

Kerið

Kerið is one of Iceland’s most visually stunning volcanic crater lakes, located in the Grímsnes area. Formed about 3,000 years ago, this ‘young’ caldera is famous for its striking contrast between deep-red volcanic rock and bright aquamarine water. Unlike many explosive craters, Kerið was formed by a magma chamber collapse, creating a perfect natural amphitheater. Visitors can easily walk the entire rim for panoramic views or descend the stairs to the water’s edge to experience the tranquil beauty of this geological gem.

Kerið offers a unique and colorful landscape with its striking red slopes contrasted against the deep blue-green crater lake. The vibrant colors change with the seasons, from vivid summer tones to snow-dusted winters, providing excellent photographic opportunities.

Kerið is very easy to access, located just off the Golden Circle route near Selfoss. The site features well-maintained paths and stairs for walking around the crater rim and down to the lake, suitable for visitors of most ages and abilities.

There is a small entrance fee of around 600 ISK (about 5 EUR/USD) as of 2025, which contributes to the upkeep and conservation of the site.

Kerið attracts many visitors throughout the year due to its popularity on the Golden Circle tour. However, it is generally a bit less crowded than the main Golden Circle highlights.
