When exploring the wonders of Iceland's Golden Circle, a brief yet captivating stop awaits – the Kerið Crater. Situated next to the road, this volcanic crater lake, approximately 6,500 years old, offers a unique glimpse into Iceland's geological history.
Initially thought to be an explosion crater, research revealed Kerið as a cone volcano. Likely erupting and depleting its magma reserve, the cone collapsed, forming a caldera – a cauldron-like pit. The reddish/blackish volcanic rock crater is oval, 55 meters deep, 170 meters wide, and 270 meters long.
The relatively shallow Kerið Crater lake, 7 to 14 meters deep, derives its beautiful opaque color from soil minerals.
Admission costs 400 ISK (€3) for adults, the short visit and unique experience make it a fair price. Note that there are no nearby restrooms.
A stroll around the top of the crater provides a panoramic view, while descending to walk around the lake offers a different perspective. The hike, though not lengthy, demands warmth due to the often windy conditions. You can complete both walks in about an hour.
