Our kayaks are all tandem kayaks for two people - you are booking per person not per kayak. If one space is left, that means there is 1 space on a tandem kayak.

Guest that are not able to complete the tour for any reason will not be provided a refund of any type.

All guests must be able to row their kayaks by themselves. One of the requirements is that you are able to get in and out of the kayak on your own and be able to maneuver it. If you are an unexperienced kayaker we highly suggest you choose the earlier tour.

If one space is left, that means there is 1 space (for 1 person) on a tandem kayak (No single kayaks available). You will be accompanied by another guest on the tour.

All guest must arrive 30 mins before the start of their tour. We respectfully will not accept or wait for any guest after this time.

If necessary, a tarp (canopy) may be used during the excursion to block any light pollution and enhanced the experience.

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

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.

Please keep in mind that this tour takes place in a natural environment and that the bioluminescent phenomenon, although rare, can be seen year round. The intensity of brightness is unpredictable and can vary from minimal to very bright suddenly.

SPECIAL NOTE: We encourage our guests to not reserve the tour on the same day of arrival to the Island, including coming from Vieques or Culebra. If the FLIGHT or FERRY is delayed and the guest misses the tour the guest will not be entitled to a refund or rescheduling.

TOUR TIME might change depending on sunset time. If so we will send a reminder for updated meeting time.

This tour takes place in the water. Expect to get completely wet. Wear clothes and shoes that can get wet. We recommend to bring a change of clothes and towel for after the trip.

There are public bathrooms on-site, but they are not always in good condition. You may consider stopping in fast food before getting to the meeting site or using the bathrooms from the nearby stores/restaurants which are sometimes available.

Certain time of the year great amounts of sargassum (seaweed) arrive to our coasts. This can make paddling to feel like a workout. Also the natural decomposition odor might be unpleasant.
