At the dam, Sterkfontein resort, Parksboard. Basic self catering. 0839421418. The wires are often not working so I tend to use the cell number. It belongs to Sam.
Wild horses Lodge, very larny and expensive. But best value with the best 'table' in the Eastern Freestate.
Gerrit 0832625104.
Qwantani Resort RCI but you can get private bookings. 058 6230882
Catapillar Catfish Cookhouse. Laid back at the top end of the dam good table. Sylvia 082 5301062
Then there are many B+B's in Harrismith. 20km from the dam.
Hope this helps
