The Caledon Resort is home to one of the Western Cape's famous Mineral Rich Warm Spring. The hot spring originate by the emergence of geothermally heated groundwater that rises from the Earth's crust. It produces over a million litres of water daily with an average temperature of 65 degrees Celsius source.
What makes The Caledon Spa's natural warm mineral pools unique is that the water is kept naturally pure - no chemicals are added. The distinctive brown colour of the water is due to the high iron content, known as chalybeate. When the water reach the surface rapid oxidation takes place which gives the distinct smell and colour of the water. The iron particles are a natural body exfoliation and the oily layers found on the surface of the pools, depending on weather conditions, a natural moisturiser to the skin.
