Forest Park in the north of Zhuhai, Tangjiawanzhen. It offers an approx. 1km walk up an asphalt route to a spectacular viewing platform.
Or you can take the 3.5km round trip to Xiaojiuzhaigou - a walk on a paved path up and down along the hillside, to then go down into the gorge and walk back through the gorge. The route through the gorge ends with a climb up a lot of stairs to rejoin the path you came on.
