Like ET with his glowing finger or Harry Potter with his wand, you'll suddenly feel like having magical powers.
When you shake the water or stroll along the beach, you'll witness a mesmerizing dance of lights illuminating the serene darkness of the night.
It's all part of the magical adventure you can experience thanks to bioluminescence, an impressive phenomenon that tints the salty waters with shades of blue and green.
So, what's bioluminescence, why is it so fascinating, and which beaches in Costa Rica can you witness it? Well, let's try to answer these questions in this luminous article.
What is bioluminescence?
Bioluminescence is one of the most peculiar and least studied phenomena in the region – they've been investigating it in Costa Rica since around 2013.
It's the production of light by certain organisms through a chemical-to-light energy transformation. You can find it in insects and fungi, but it's more commonly observed in bodies of water, especially in marine ecosystems. There are only a few reported cases of bioluminescence in freshwater worldwide.
The major groups of microorganisms involved in aquatic bioluminescence are bacteria and dinoflagellates (a type of phytoplankton). Experts say bioluminescence's color depends on the species that produce it and how it's perceived by the human eye.
This fascinating event is more easily observed at night, and in Costa Rica, it has been reported in both the Pacific and Caribbean Oceans, mainly in Guanacaste and Puntarenas – popular fishing and tourist spots.
Bioluminescent hotspots in Costa Rica
One of the main spots is Isla Chiquita in the Gulf of Nicoya, where the waters come alive with a captivating sparkling show on moonless nights.
You can join expeditions on small boats to experience the bioluminescence firsthand.
While these events are spontaneous and not predictable, local fishermen have noticed some trends related to moon phases, rainfall, and tides. So, with a bit of luck, you might witness a trail of twinkling lights forming as boats pass by.
Other beaches that have reported this fantastic phenomenon include Rocas in Montezuma, Punta Cuchillo and Isla Cedros in Paquera, and El Cocal and Caldera in Puntarenas.
Besides boat or kayak tours, some of these destinations offer the opportunity for nighttime snorkeling or simply walking barefoot on the sand while admiring this dazzling natural spectacle.
Although there have been sightings in the Caribbean, researchers still don’t have photographic evidence.
Book a tour in Puntarenas
If you're already daydreaming about experiencing this sensory delight, we've got some great news for your next Costa Rican vacation.
