Bioluminescent Bay Tour

Imagine bathing in the warm waters of the Caribbean whilst thousands of tiny lights start to illuminate your path. Experience it with this luminous plankton tour!

Bioluminescent Bay Tour

We'll pick you up from your hotel in Bocagrande or one of the other meeting points, between 1 and 2 pm. There will be an hour and a half minibus journey to reach Playa Blanca, on the island of Baru. When we get there we'll have two hours to enjoy the views, the sunset and an intriguing and informative talk about the luminous plankton which exhibit this spectacular phenomenon! 

At 7 pm, once the sun has set, we'll get on the boat which will take us to the Puerto Naito cove. When we reach the area you'll see how thousands of small blue dots start to shine in the water. You'll think you're dreaming!

We'll anchor the boat and put our life jackets on to jump into the water. You'll be able to see how with every movement you make, the water will start to shine, and then the light will fade again. Have you ever seen anything like this?

You'll certainly enjoy swimming in this picture-postcard area; one of very few in the world home to luminous or bioluminescent plankton. After this incredible experience, we'll get back on the boat and return to Playa Blanca, have a snack, and then head back to the tour pick up point at 9 pm.
