Ban Gioc Waterfalls, located on the Quay Son River along the Vietnam-China border, is a breathtaking natural attraction in Cao Bang Province. The falls are most impressive during the rainy season (May to September) when the water flow is at its peak; however, the dry season (October to April) offers easier access and clearer water. While the falls are generally accessible, some areas may be challenging for visitors with mobility issues. Independent exploration is possible, but guided tours offer deeper insights into the local culture and history. A typical visit lasts 2-4 hours, and the approximate cost, including entrance fees and boat rides, can range from $10 to $30 USD. Be aware of seasonal changes that may impact accessibility and water conditions. Consider packing light, wearing comfortable shoes, and bringing rain gear depending on the time of year.
