Glistening Waters for sure! Amazing! Don't go on a cruise ship day. Mobay undersea tour. Again, don't go on a cruise ship day. Make reservations. Blue Hole at Roaring River. Glistening Waters (Luminous Lagoon) is the best. Capt Jerry told us there are only 4 in the world, but the biggest and brightest is in Jamaica. We got Gary to fall back into the water and it looked like a million light sticks exploded around him! Truly a natural wonder! Only USD20 for the boat tour, I think. Great, reasonable resto on site, too.
