These paintings could represent the concepts of heat, energy, creation and growth and may be associated with the trance dance. This dance produces an altered state of consciousness in which, the Bushmen believe, the dancer can heal the sick and control the natural and supernatural. The paintings depicting a mythological snake may corroborate this, as snakes in Bushman and Bantu mythology are associated with rain.
The schematic patterns may also have meanings - perhaps to do with creating rain to bring health and prosperity to all living things. Even the painting sites chosen on the hills would seem to point to their spiritual and religious significance. Many are on high, inaccessible cliffs, with commanding views over the landscape. This could indicate an authority and control over the sky and earth, or protection for those living on earth. It would seem that little or nothing about the paintings was haphazard.
Archaeological research at the hills has recently challenged previously held ideas about human migrations to southern Africa.
Scientists have identified the shorelines of a small lake. Among the rare artifacts found there are some animal bone fish hooks dating back more than 20,000 years. Other archaeological discoveries include the location of mines among the hills. There is evidence that between AD 800 and 1,100 the people at Tsodilo were engaged in mining black hematite, and possibly mica, and trading it through the extensive trade networks of Africa.
The Tsodilo Hills is one of the most historically significant rock art sites in the world with 500 individual sites charting thousands of years of human habitation. There is a small San encampment nearby as well as a village near the Male Hill inhabited by the Hambukushu people. Guides are available at these settlements.
The track to Tsodilo Hills is extremely rough and suitable only for four-wheel-drive vehicles. The turning off the main Maun/Shakawe road is just south of Sepupa and is indicated with a National Museum signpost. There are no designated campsites in the area and camping is permitted anywhere, but again, be sure to treat Tsodilo with respect.
