It was great! We did not use the transportation portion as we were staying nearby and met at the Bay. The night kayaking was super fun and challenging (I would not recommend this trip for people who have no kayaking experience.) My husband and I are both experienced kayakers and found it to be a bit challenging (but in a good way!) the Bio Bay was magical! So glad we did this activity!

The Kayaking at night was an amazing experience, Danny and Felix were great guides with tons of info and made me feel safe.

Then, paddle in a two-person kayak through the mangrove channels leading to the natural reserve of the Laguna Grande.

Then, see the microscopic plankton capable of producing natural light at the touch of your hand. Explore these amazing organisms up close as your professional guide takes you on a journey to discover all their secrets.

This is definitely an activity that will be most enjoyed by people who like natural things like rocks, plants, and nature stuff. Not everyone will be wowed. There is a bit of a drive to get to the location, but since there are only 5 bio bays in the world, an hour road trip is no problem. Once we got to the rally point the bathrooms are in the tower and that's where you'll change clothes if you choose. To get to the kayak you can take off your shoes as you walk in the water to your kayak. I am just over 5ft and the water was below my hips. If you don't like being uncomfortable you will not like this part. Rowing through the mangroves in the dark was a very cool part of the adventure. Listening to the wild sounds and looking at the stars was beautiful. The glow was already visible. We rowed out to a wide open body of water and splashed our hands in and it was incredible. Like nothing I've ever seen. The kayak next to me had a girl ~10yrs old. She was giggling and loving it.
