ONE of Jamaica's many natural attractions the Blue Lagoon of Port Antonio, Portland might be just as mysterious as it is blue.

It is said to be bottomless and the waters supposedly act as an aphrodisiac.

This myths surrounding the lagoon are filled with mystique and allure and some legends even claiming that a dragon resides beneath the waters.

However, as far as has been proven, the Blue Lagoon is over 180 feet deep and is supplied by multiple freshwater springs within the surrounding mountains which enter the lagoon at about 131 feet.

The waters are surrounded by a tropical garden and natural, lush flora. Although being open to the sea through a narrow channel it is seen as the largest of Jamaica's spring-fed lagoons.

The Lagoon is famous for its striking blue colour, which changes through the full palette of blue shades. The colour of the water ranges from turquoise to azure to sapphire depending on the light from the sun. This is said to be resultant from the great depths as well as the cold mineral water, which oozes from beneath this magical site.

The water varies in temperature, having a cool top layer with warmer layers underneath. Its mix of freshwater for spring and salty sea water has proved a favourite of locals and tourists alike for activities like swimming, diving, kayaking, and rafting.

Premier Norman Manley first sent a preservation notice to his cabinet in 1951 in order to ensure the continuation and protection of the beautiful Blue Hole area in Portland.

This area was later renamed the Blue Lagoon after the great success of the movie Blue Lagoon, which was shot entirely in the area.

Some locals, however, still refer to it as the Blue Hole.
