Kerið, Iceland While many crater lakes are deep within black volcanic rock, the rock around the colorful Kerið Lake in Iceland is a mix of red, brown, and pink. The crater sits within the tourist route known as the Golden Circle.
Lake Retba in Senegal which is also called Lac Rose or the Pink Lake. Water is turned pink due to a specific micro-algae and has salt saturation which means you can just float in it. I want to go here.
