I have been to Glistening Waters a couple of times and it was great fun. It's best if it has been a sunny day in Falmouth - those little bioluminescent guys give a better show after a day in the sun! Also, better when there aren't any cruise ships in. Captain Jerry is great! So animated. It is truly a beautiful natural phenomenon! You'll not see anything like it anywhere! I would recommend you take a chance and go for it. There is a dandy little resto on the site where you get the tour boats - good service and pretty good food. You can swim in the water at the end (totally awesome! Capt. Jerry told my husband to just fall off the back of the boat into the water and it looked like a bazillion light sticks exploded around him! You can't see the people swimming in the water, just their outline - it's amazing!). The bottom is pretty mucky, so you might want to have water shoes, and be able to take a shower ASAP when you get back to you hotel. No danger or anything, its just kind of an ookie feeling after a bit.)

It's probably my favorite place in Jamaica and would take anyone there, of any age.
