Swimming with Bioluminescent Plankton at Isla Mucura

Once the sun sets over the Caribbean horizon and the clear blue waters turn to darkness, dip your head below the surface. Among the coastal mangroves off the coral island of Mucura, you’ll suddenly be surrounded by an otherworldly scene.

Speckles of blue-green light will ignite the dark waters like the ocean’s very own stars. Tiny bioluminescent plankton produce a chemical called luciferin which glows with your soft movements in the water. A night-time swim is an ideal adventure, for it immerses you in a surreal natural world. 

Underneath the night sky, you’ll find yourself swimming amongst the ocean’s version of the northern lights.
