Blue Hole

A Blue Hole is a natural underwater sinkhole, typically found in coastal areas. These deep, circular formations often connected to the ocean and are characterized by their vibrant blue color due to the depth of the water. They can vary in size and depth and are popular for diving and snorkeling because of their unique ecosystems, clear waters, and diverse marine life. Blue Holes also serve as windows into geological history, revealing insights about past climatic conditions and oceanic changes. Notable examples include the Great Blue Hole in Belize, which is a UNESCO World Heritage site.
