Kloofwaters has been run as a Christian Campsite by its owners, Bob and Beryl Laburn, for over 20 years. It is situated on the northern slopes of the Magaliesberg, about 120 km from Johannesburg, and is equipped with basic dormitory accommodation for up to 80 children, a kitchen, dining area, classroom, and beautiful stone chapel. A clear mountain stream runs through the 150 hectare property, there are four small dams, and beautiful unspoilt areas for swimming, hiking, rock climbing and bird-watching. 

In 2002 St Mary’s and St John’s took over and jointly leased the property from the Laburns, with the intention that it should function as an outdoor campus for the two schools. It has since provided wonderful opportunities for children to explore the outdoors and have adventures, with hands-on learning about the environment and ecology. It has been a centre for Christian camping, team-building, and the development of personal, interpersonal and leadership skills. This era of Kloofwaters was started by Mr Brett Nicolson and Ms Jenny Ketley and has grown to a vibrant and busy organization that continues to serve St Johns and St Mary’s schools. Many children from all over the greater Johannesburg and Pretoria metropolitan areas have set foot on the farm to enjoy its treasures.
