During our Ocean Odyssey trips we often pause to observe certain geological features at the Knysna headlands and all along our spectacular coastline. One very unusual feature seldom seen in this area is an ocean front cave bearing stalactites. These caves are known as The Needle Caves.
Originating from the Greek word stalasso meaning “to drip”, stalactites are formed from the deposition of calcium carbonate and other minerals. Shaped like an icicle, all stalactites begin with a single mineral-laden drop of water and are formed over thousands of years by the dripping of percolating calcareous water.
