Cao Bang

There are no rail connections, making buses the most convenient way to get to Cao Bằng. A bus from Lạng Sơn on the China-Vietnam border take 4–5 hours and costs 50,000 dong. There are also buses from the neighbouring provinces in northern Vietnam.
You can rent a bus from Hanoi to CaoBang, about 5 hours on road, cost around 15 USD.

Cao Bằng is easily navigated on foot, but xe ôm (motorbike taxis) are convenient and cheap.
The Bằng Giang River splits the city into two. The bus station is on the eastern side of the river; cross the bridge to find the main street, Kim Dong (parallel to the river), the market and most of the hotels.

• Thang Hen Lake - surrounded by mountains, this serene lake is at its best in the rainy season. During the dry season the lake shrinks and is not as impressive, but there are a few rafts that you can take. Walking in the nearby mountains brings you past local herders and farmers. There are no buses to Thang Hen, so the cheapest option is to hire a motorbike driver for the half-day trip. It's about 1 hour away, and try to negotiate a round-trip price of 125,000 dong. No entrance fee.
• Ban Gioc Waterfall - this breathtaking waterfall, the largest in Vietnam, straddles the China-Vietnam border. The water is particularly thunderous in the wet season but is still beautiful during the dry. You can take a raft out into the river to the base of the falls and greet Chinese tourists doing the same from the other side. Ban Gioc is about 85 km from Cao Bằng, about 3 hours away. The cheapest way to get there is to take a public minibus to Trung Khanh for around 50,000 dong. Once in Trung Khanh, the minibus driver may offer to take you the rest of the way to Ban Gioc for an extra 150,000 dong, which includes waiting time, the nearby Ngườm Ngao Cave, and the return trip to Cao Bằng. You can also rent a motorbike in Trung Khanh to take you the rest of the way to the falls (about 20–30 minutes). Those with a larger budget may consider renting a jeep for the day. No entrance fee, but you may be charged 2,000 dong to cross the bridge to reach the falls.
• Nguom Ngao Cave - ask your driver to take you to Nguom Ngao before or after Ban Gioc. This immense cave holds a series of majestic, jaw-dropping caverns, filled with delicate, intricate formations of stalactites and stalagmites. In the low season, you may even have the cave to yourself, which is an experience probably not to be had elsewhere. Optional guides will helpfully point out particularly interesting rocks and bat roosts. 5,000 dong.
• Pac Bo Cave

Many minority tribes live in the area surrounding Cao Bằng, and their village markets make fascinating places to visit. Markets take place according to the lunar calendar, and the early morning is the best time to go. Hiring a motorbike is the only way to get there.

There are two fruit and vegetable markets on the western side of the river. The more organized one sprawls under a roof just north of the bridge along Kim Dong. It also sells some cooked foods and household goods. The second market stretches along the river south of the bridge and is only in the morning. Women from the countryside spread their fresh fruits and vegetables on blankets or in the baskets used to transport them.

There are few restaurants in Cao Bằng, and those that exist are expensive by backpacker standards. Fortunately, eating on the streets is delicious, easy and cheap. For breakfast consider bahn mi, which toasted baguettes filled with cuts of pork, egg, cilantro and a sweet-spicy sauce. A woman on Pho Hoang Nhu, a few minutes' walk north of the Bac Lam Hotel, makes particularly tasty bahn mi. Pho shops line the street facing the bus station (around 12,000 dong per bowl).
By dinnertime, certain areas become temporary food markets, with each area specializing in a certain dish. Walk south down Kim Dong from the bridge to find chao (rice porridge) and stir-fried instant noodles. On Kim Dong just south of the bridge there are several stands that serve pho and fried rice. For a sweet dessert, in the evening women set up small tables on the streets, where they cook sticky rice balls in a sweet ginger soup. Serve with crumbled peanuts on top, this is the perfect way to end a day of eating on the streets.
