I really enjoyed the night-time kayaking in the Biobay. It felt like an adventure! I was a little underwhelmed by the bio luminesence in the water... didn't really know what to expect. With that said, we did see it and it was still pretty neat. Javier was a great guide. We absolutely loved looking at the night sky and learning about the constellations. Bug spray is a must. This trip is not for someone afraid of the dark, bugs, or some physical effort. You will get a workout.
