FROHG members are involved with maintaining the Hiking Trail which meanders through the grasslands and forest patches .
Historian and local resident Prof. Louis Changuion laid out the original trail in 1993. At times it fell into disuse but various organisations and Haenertsburg residents have played a role in maintaining it. The Haenertsburg Development Foundation (HADEF), obtained lottery funds to do this, and HEMAG members assisted in administering these funds and in physical work in maintaing the trail. Individual Haenertsburg residents who were not necessarily HEMAG members also helped in alien plant removal, clearing the trail, and labelling trees.
The Trail Map and brochures on the fauna and flora are available from various shops in the village.
