The Boiling Hole is an underground connection to the ocean.
The Boiling Hole is a naturally-formed subterranean underwater fissure passage that connects the ocean to the main
salina pond on South Caicos. This formation was taken advantage of by early
sea salt producers, who converted it to feed sea water into the salt pans to be evaporated.
The name Boiling Hole was derived from the agitated state of the water when flowing in through the hole during
Today, you can walk out to the Boiling Hole from the
Cockburn Harbour side of the main salina. A twenty foot wide low white concrete structure surrounds the feature, along with the remains of gates to control the water output.

As was the case with nearly all of the
sinkholes, blue holes and caves found in the Turks and Caicos, The natural hole was created by what is called the karst process: the slow action of slightly acidic rain water dissolving the soft limestone as it drained to the water table.
These cave systems typically formed without an opening to the surface. Ceiling collapse and erosion was the usual force that eventually revealed the hidden chasm.
Several of the shallow ponds and salinas in the country have subterranean systems that appear to be connected to the ocean similar to the Boiling Hole, or remnants of such.
The incredibly scenic
Lake Catherine on
West Caicos is home to one such example.
How to Find the Boiling Hole
To get to this feature, follow St George's Street west from
Cockburn Harbour onto the salina. A recently-regraded 700 foot (220 meter) limestone causeway leads to a small parking area.
Once at the parking area, It's a short walk along the top of the salina dividing walls out to the Boiling Hole.
Due to the maze-like network of dividing walls in the salina, it may be easiest to simply ask for directions.
