Too many people, bordering on dangerous because it is got so crowded and because its dark it is a bit alarming in the narrow channel. Very disorganized… one hour late starting with nowhere to sit while we waited. Bioluminescent was minimal so not really work the efforr

My real issue is that this was advertised as a small tour (max 13 people) and there were about 35 people on this tour. There were 4 tour guides but it was all one big group. It was fun to kayak at night but there was very little bioluminescence to see. Parts of the ride through the mangrove are in complete darkness so can be hard to navigate even with some guidance. Best to have some kayaking experience. I can’t remember the age suggestions but there was no way my 10 year old would’ve been able to navigate it on her own, fortunately she was in a double kayak.

This group is awesome. It was a big group going out but you had enough guides to make it easy to follow along the dark waters. Very cool to see the bioluminescent plankton. Like sparkles of light in the water, very cool. Seriously, very nice staff and helpful and was a great experience.
