Bring Toilet Paper!
Bianca_B, Dec 2021
We got picked up at 5:50 at the Marriott Stellaris in an air conditioned shuttle bus. There were two more stops before getting to the bio bag, one at a hotel in Isla Verde and another stop near El Yunque. In total, the commute from our hotel with stops was about 1hr and 20 min. Our driver was a sage driver and ver professional. Once you get there, you do have time to use the restroom at the local park. There is no toilet paper, so you have to bring your own. There is a water spigot to wash your feet, which was great. You can leave your change of clothes, Phones and snacks on the bus since the driver stays with the bus while you are on the excursion. The boats were in great shape and there were three guides for the group of approximately 30 people (15 boats). The life jackets were in good shape as well. We had a group of mixed skill level, including kids- which meant for a few random oars flying and bumper boats. There are other four groups out at the same time, and during the approx 45 min paddle to the bay (up stream) we had cross traffic that caused a few pile ups. It is very dark so you have to be aware of mangrove trees and vines above you and on each side. You spend about 20 min in the bay experiencing more of the biolum. The way back is easier because you are going with the current. You do have to wear a mask when you are with the larger group. After the excursion is over, they have small bottles of water. Most people head to the restrooms to change into dry clothes and wash their feet. The ride back is uneventful- we got back into the bus around 10pm. This is not a tour, it is an activity. We enjoyed it, but it does take a chunk of your evening. Good workout.

Bioluminescence bay was good but it takes long time to go there and therefore we were kind of tired when we arrived but also we anticipated the trip

Epic: like a scene out of a movie.
Ophelia_L, Nov 2021
The nature of it all!! Happy to be able to share these experience with my daughter. We are from NY-“concrete jungle” so this was of course out of known element. The experience will be something to remember. Tour guides where edifying, and ensure safety at all time while simultaneously entertaining.
Get ready for lots of fun

Viator is untrustworthy!
Kevin_P, Oct 2021
Viator is bad at communication. Use another source. They will take your money but then you are on your own and they don’t help and people will lie to you over the phone about why you can’t go even though you booked hours in advance. Makes zero sense.
Set low expectations and its physically challenging
Karen_L, Oct 2021
I didn’t see a little more than a few sparkles here and there the glass bottom helped letting through those few sparkles otherwise it’s just physical exercise
