Diving inland in South Africa/Komati Springs

From Wikitravel
Jump to: navigation, search

Komati Springs used to be a mine prior to 1972. When mining because unfeasible, equipment was pulled out, and they ceased pumping out water. The groundwater rose back naturally, thus providing a dive site of note. This left an open hole to 54m, and a cavern and cave system from 9 m to 186m. Water in the hole reached reaches up to 26 degrees in summer, and never drops below 16 degrees in winter. Visibility is 10 – 20m. There are grids at 5, 10 and 30 meters. The site is 915m above sea level, so not as high as the Gauteng sites. Weather is normally good, and dive conditions are always good.

Komati Springs lies between Badplaas and Barberton in the Mpumalanga province of South Africa. It is at an altitude of 915m above sea level.


Komati Springs, is one of the most popular technical diving and technical diver training sites in inland South Africa due to the depth, accessibility, overhead environment and consistent conditions. It is also good for recreational divers as it has an open portion with training grids.

Maximum depth in the cave system is 186m, and 53m in open water.


5 to 40m.


The area is surrounded by the oldest mountains on the planet dating back to 3.7 billion years. This is a Greenstone Belt area, and these are zones of rocks left over from the original portion of the Earth. It is the oldest well-preserved real estate on Earth. Dotted throughout the area you can also see Komatiites - outcrops consisting of the hottest rocks ever to erupt on the planet. They are named after the Komati River, which in turn carved out the Great Nkomati River Valley. The surrounding grasslands represent the most threatened biome on Earth. .

Geology: The site is an abandoned and flooded mine. The surrounding area has been rehabilitated and is safe.


The water temperature varies seasonally. In summer the surface temperature can rise to 25°C, dropping to about 20°C at about 30m, and 17°C at depth. In winter the water drops to a constant 16 to 17°C throughout the water column.

The site is diveable throughout the year.

Aquatic life[edit]


The cave system of the abandoned mine is a three-dimensional maze with lots of exploration opportunities.


Suggested Routes[edit]

Stay safe[edit]


Cave certification is required to be allowed entry to the overhead areas, unless you are being trained as a cave diver by a qualified instructor at the time. Certification (recreational and technical) must be appropriate for the planned depth of the dive.


Cave diving equipment is necessary for penetrations. Open Water (recreational) equipment for the open hole.
