On all the islands of Malta, you will find natural pools. These are true wonders of nature. They are often formed from the coast’s rocks and have deep blue water. Where does this blue colour actually come from? Water is transparent, which you see when you swim. Yet, the Maltese waters look deep blue. Especially in Malta. The reason is that the sea, silt particles, and plankton extract the red light from the sun's rays and the sea reflects the blue rays back. Combine that with white sandy soil and the sea reflects an azure blue colour that we know as lagoons.
