Toraja divided into different geographic groups, the most important being Mamasa, centred on the isolated Kalumpang valley and the Sa’dan of the southern Toraja lands. Known as 'Tana Toraja', Sa'dan has the market towns of Makale and Rantepao. There have never been any strong lasting political grouping within the Toraja. Good roads now reach Tana Toraja from Makassar, the largest city in Sulawesi. This brings in a seasonal influx of foreign tourists who whilst injecting their money into the local economy have not yet had much lasting impact on local people’s lives.
