The Rosario Islands National Park is a group of islands on the Colombian coast, located just 1 hour by sport boat from Cartagena. With this plan you will enjoy the most complete tour of the city, visiting different beaches of Baru and the Rosario Islands. You will experience snorkeling in crystal clear waters, white sand and coral reefs, which is a breathtaking experience! The day will end with a unique, magical and incomparable activity: experiencing the Bioluminescent Plankton.
Certain creatures both on land and sea can produce light through chemical reactions taking place within their bodies known as Bioluminescence. The bioluminescence results from a light-producing chemical reaction also called chemiluminescence. Certain types of chemicals when mixed together produce energy which ‘excites’ other particles on vibration and generate light which causes the glow. The group of chemicals involved to make plankton glow are broadly termed luciferins and the light is produced by a series of oxidation reactions set off by a catalyst called luciferase. The bioluminescence in plankton is very high in several forms of Plankton and is a form of cold light or luminescence.
