Nanling National Forest Park — Hiking (3hr)

Nanling National Forest Park (南岭国家森林公园) straddles the Guangdong-Hunan border and is one of the most biodiverse forest ecosystems in China, home to ancient nanmu trees, waterfalls, and rare subtropical flora. It is a popular hiking and camping destination for Guangzhou and Shenzhen families. Travel: 3 hours from Guangzhou by coach to Ruyuan County. Best March-April (azalea bloom) or September-October. Not a simple day trip from HK — better as an overnight. China visa required.
