Xiong'er Mountain Great Rift Valley is a developed geological scenic area outside Zaozhuang, known for narrow rock passages, wooded slopes, and short walks through the mountain terrain. It offers a natural contrast to the canal and mining-history sights closer to the city.
The site is arranged for domestic day-trippers, so expect paths, signs, and set viewpoints rather than wilderness. It is worth considering if you have a car or driver and want a half-day outdoors.
