The waters that launched Brooke Shields’ movie career are by any measure one of the most beautiful spots in Jamaica. The 55m-deep ‘Blue Hole’ (as it is known locally) opens to the sea through a narrow funnel, but is fed by freshwater springs that come in at about a depth of 40m. As a result the water changes color through every shade of jade and emerald during the day, thanks to cold freshwater that blankets the warm mass of seawater lurking below.
You may encounter boat operators eager to take you on a short boat ride (US$20) to nearby Cocktail Beach (where parts of the Tom Cruise movie Cocktail were filmed) and rustic Monkey Island, a short distance away.
The lagoon is accessible from the road and is public property, but the area is under development so an entrance fee may soon be on the cards. Note that if it's been raining heavily, run-off water from the hills turns the lagoon a disappointing murky green.
