Ban Gioc-Detian Falls
Thac Ban Gioc / Detian Falls
The largest waterfall straddling an international border in Asia is known by two names on two sides of a single river, with bamboo rafts ferrying visitors between the Vietnamese and Chinese viewpoints without ever technically crossing customs. Multiple limestone tiers spread the water across a wide, terraced curtain visible from both countries at once.
