The park is located on an inland dune and contains several significant features including Caroline Sinkhole, situated in the north-eastern corner. View the sinkhole from a suspended platform near the main car park on Carba Road.
The large sinkhole has collapsed into the underlying marine limestone. Look closely and you will notice the varying layers of the limestone in the walls.
Where sinkholes reach the watertable and have vertical sides, like Caroline Sinkhole, they are often called cenotes.
The watertable is presently low and only exists as small pools around the edge. Changes in vegetation types, clearly visible from the elevated viewing platform, indicate former water levels.
There are also several dolines scattered throughout the park. Dolines are formed the same way as sinkholes, but do not reach the watertable and often have gentle sides. The largest doline is located near the southern boundary.
The area was occasionally used as a military training camp during World War Two.
