- Due to the immense popularity the Bio Bay tour, at times can get crowded. It’s not uncommon to meet up with other tour groups waiting to access the canal leading to the lagoon. There can be bumping other kayaks along the way. When crowded conditions warrant, Pure Adventure will provide extra guides for your safety.

- In order to best appreciate the bioluminescent phenomena our tours run at sunset and early evening and it can get quite dark in the mangrove canal. So, if you are afraid of darkness, a first time kayaker, or have small kids we strongly suggest taking the earlier, sunset trip. This way you can see where you are going, get use to the environment and sharpen your kayaking skills
