Cao Bang
Karst landscapes on the Vietnam–China border and a UNESCO Global Geopark, with Ban Gioc Waterfall, Mat Than Mountain, Thang Hen Lake, Pac Bo and Nguom Ngao Cave scattered among the mountains.
Cao Bang (Cao Bằng) is a mountainous province in northeastern Vietnam bordering China's Guangxi, and its capital, Cao Bang City, lies about 280 km from Hanoi. The province is known for its karst peaks, caves, highland lakes and Tay and Nung villages, and in 2018 Non Nuoc Cao Bang (Non Nước Cao Bằng) was designated a UNESCO Global Geopark. Most travelers base themselves in Cao Bang City and follow two routes. The eastern loop runs along Highways 3 and 4A past Thang Hen Lake, Mat Than Mountain, Ma Phuc Pass and Phia Thap incense village to the Vietnamese side of Ban Gioc Waterfall in Trung Khanh District, Truc Lam Ban Gioc Pagoda and Nguom Ngao Cave — about 85–90 km one way, with most visitors spending a night in a stone village near Ban Gioc. The northern route runs about 55 km to the Pac Bo relic site in Ha Quang District, where Ho Chi Minh returned in 1941 to lead the revolution. In the southwest, Phia Oac–Phia Den National Park rises to nearly 2,000 m and occasionally sees frost and snow in winter. The best time to visit is Sep–Oct, when the rice fields turn gold and the waterfall is still full, and November, when buckwheat blooms; the Jun–Aug rainy season makes the waterfall most spectacular but brings landslides on mountain roads, while Jan–Feb is cold, gloomy and foggy. Overnight sleeper buses from Hanoi take about 7–8 hours, or you can drive or ride a motorbike. Allow 2–3 days. Note that Ban Gioc Waterfall sits right on the border — do not cross it; accommodation and ATMs are limited in some villages, so bring enough cash. Ba Be Lake to the north is a separate destination.
