We booked two tours with Bucaneros and were very satisfied. We especially enjoyed a trip with Carlos on the boat, where we saw a huge pod of dolphins and were treated to a delicious meal in a beautiful bay. Carlos is a relaxed, caring, and friendly guide. If you're still hungry or thirsty after the tour, the family-run restaurant El Bucanero is a great option.

Sunset & Bioluminescence from Drake Bay
Sail to one of Drake Bay's most beautiful beaches for the sunset, then swim after dark in bioluminescent water that lights up with every movement.
What to expect
A scenic boat ride takes you toward a remote beach for golden hour over the Pacific, with stargazing once the light fades and the crowds disappear.
After dark you swim in bioluminescent water that glows around you as you move — a natural light show. Boat, drinks and safety gear are included.

Couples, families and anyone who wants one unforgettable evening. You swim in a life vest with the guide, so confidence in the water matters more than technique.

Frequently Asked Questions
What is bioluminescence?
Microscopic plankton in the water that flash when they are disturbed. Move your hand and it lights up around you; the wake off the boat glows. It is a living thing, not a light show, which is why some nights are far brighter than others.
Is it guaranteed?
No, and anyone who guarantees it is not being straight with you. It depends on moonlight, plankton and the water that week. We book around the darkest nights we can and we will tell you honestly if your dates look poor.
Do I have to get in the water?
You can watch it from the boat, but it is best to swim with a life vest and alongside the guide. The experience is more intense when you are in the glow.
Can I photograph it?
Honestly, barely. It is very faint to a camera and almost every photograph you have seen of it is enhanced. Bring your eyes rather than your phone for this one.
Is it suitable for children?
Yes, and children tend to be the ones who react best to it. They wear vests and stay with the guide. The trip is over by about 7 PM, so it does not run late.
Is this tour refundable?
Yes. If you need to cancel, contact us as soon as possible so we can arrange your refund.
Hear from travelers who chose us
The bioluminescence tour was wonderful. Carlos and Carlos or friend will take you out on a multipurpose boat, the same one their family uses to catch fresh fish for their restaurant. This type of bioluminescence is reactive to the touch. In Drake Bay in mid-July, we went out into the middle of the bay and swam in life jackets. They were willing to do a private tour for a bit longer for a little more, and were very flexible and nice. I felt comfortable at night with a ratio of 1 guide to 3 people, so if swimming in a lifejacket at night in the bay is scary for you, you might inquire about that. It is difficult to climb up to the boat without a ladder on your own, but extremely easy with the captain's helping hand. This bioluminescence is not easily photographable and requires at a minimum a very very large aperture DSLR with very high ISO and sensitivity, and even then it's extremely faint. Think of it as bright as small ephemeral stars in the water, a few dozens whenever you move. The snorkeling goggles are not compatible with prescription glasses, but I preferred personally the clarity of no goggles (which can get foggy), while my companions preferred with goggles. Any night is good as long as the moon is not up in the sky (new moon or near new moon is fine any time of night, but anything else and you have to check the lunar hour by hour moonrise moonset time table). Very nice family, who helped us out a few times when we forgot an item or two. Tasty drinks and food at their restaurant too. Another unnamed popular agency across the street cancelled another bioluminescence tour we booked, disingenuously claiming "weather" (seemed fair weather; I think they didn't get enough customers that night), but Bucaneros Corcovado Tours is very good. Bucarenos Tours honored the scheduled time and has always been straightforward and honorable, and we greatly enjoyed their kindness/hospitality and experience. Muchas gracias para todos 🤎
Thanks Carlos for the amazing kayak tour showing us the bioluminescence! After paddling out in the sea for a while, the biolumnescence was clearly visible from the kajak and even more while swimming in the sea. It was magical!
We booked the Sunset & Bioluminescence Tour as a family, and it was absolutely amazing. Carlos and his friend did an outstanding job throughout the experience. Our kids especially loved when they cut fresh coconuts from the palms and prepared sugar cane for us to try. They even brought along cold beers, which we enjoyed while watching the sunset from the boat. Later, swimming in the glowing water under the pitch-black, starry sky felt truly magical. We can without hesitation recommend this tour. If you're interested, it’s best to visit Bucaneros Restaurant and arrange it directly with them, as the website still needs a bit of improvement . Its worth it! :)
My wife and I were impressed by the professionalism and knowledge of Carlos during our inshore fishing tour today. He tried different spots, different techniques in pursuit of the best experience. We caught Bonito Tuna, Red Snapper, Spanish Mackerel, and Jack. The Jack fish was served at the El Bucanero Restaurante in a Ceviche dish - muy deliciosa!
