We found ourselves asking, why is the water in Greece so blue? To answer, it is a reflection of the sky. We have that in Florida though? What makes this different? It is because the water does not contain much solid matter, such as plankton, mud, and dust particles that could easily float up and cloud the view. It is very rocky, which also helps to filter the water and they cannot be picked up and travel easily, keeping the view clear. In that case, take Rick Steves' advise and bring water shoes!
