Bioluminescent plankton: how to experience Isla Múcura’s most magical night
What it is, why the water glows, when it is best to see it and what the night tour from the hotel is like.
Some experiences can’t be put into words. You move your hand under the water and the sea answers with thousands of blue sparks. That is the Bioluminescent Plankton Tour, the night activity most talked about by visitors to Isla Múcura.
Why the water glows
The glow comes from millions of microorganisms called phytoplankton that react with light when the water is disturbed. As you swim or move your hands, the sea comes alive with a bluish luminescence that seems out of this world.
When it looks best
On dark nights, without a full moon. The hotel schedules the outing according to conditions so the show is as spectacular as possible.
What the tour is like
- It takes place in small groups, with trained staff and life jackets.
- It costs $70,000 COP per person.
- It is suitable for couples, solo travelers and families.
- It is part of the hotel’s commitment to responsible tourism: we observe, we don’t disturb.
Bring a swimsuit and a towel; the water is warm. And leave your phone on the boat: this is something to see with your own eyes.
