In the south of Iceland, a day trip from Reykjavik, there is a 3,000-year-old volcanic crater with unique volcanic rocks.
This shallow lake is within the easy hiking trail and visitors can get a closer view of it. The Kerid Crater Hike is a magical experience. The opaque aquamarine shade of blue water is a result of the minerals from the surrounding soil.
The lake is a breathtaking view with vibrant green moss around it and red slopes. It is the result of an eruption over 3,000 years ago, but the crater itself is believed to have been formed 6,500 years ago and known as an “explosion crater”. The explosive eruption made the magma in the center deplete itself, and the foundation for the water pool was formed.
The bright, sapphire-colored water is covered in rich green moss on one side. The bright rainbow of colors looks magnificent.
