OK.
there are 3 go-karting tracks in ZhuHai as per my knowledge (could be more).
1 - beside the ZIC....very far off...need to take a taxi to get there
2 - in the park near the statue of the girl with the pearl
3 - in the basement of a building in the pub area
all three are good fun.
if you can shell out a little cash, at the ZIC, you can get a ride on a 2 seater Formula car driven by an experienced driver around the ZIC track to get a real feel of high speed racing.
