The dive site Komati Springs or Badgat is an inland freshwater cave system in a flooded mine at the foot of the mountains between Badplaas and Barberton in the Mpumalanga province of South Africa. It is at an altitude of 915 m 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.
