Kerid Crater

About

Kerid, also written Kerið, is a striking volcanic crater lake tucked into the south Icelandic Grímsnes area along the famous Golden Circle route. The caldera, about 170 m wide and 55 m deep, is formed of bright red basalt walls that contrast vividly with the aquamarine lake at its bottom, a result of mineral deposits that give the water its color. It is one of Iceland’s most iconic natural sights, attracting thousands of visitors who come to admire the dramatic geological layers and the simple, picturesque trail that circles the rim. Admission to the crater costs a modest 600 ISK, which grants entry to the walk‑around trail and the lake itself. The site is open whenever the sun shines, making it possible to explore day‑timed hours from early morning until sunset. Visitors can walk freely to the crater’s edge, sit on a bench overlooking the water, or descend to the lake’s bottom for a closer look—ideal for photographers and nature lovers alike. The best time to visit Kerid is late spring through early autumn, when mild weather and longer daylight hours make the walk more comfortable. Summer crowds can be heavy, so arriving early in the morning offers a quieter experience. For larger groups or tour operators, advance booking can be arranged directly via the site for a smoother visit.
