South of Guilin, in China, you can find the biggest karst formation of the world. The erosion has created unique mountians that are cut by different rivers: Li River, the biggest, is the main way to reach Yangshuo by a cruise boat. Yangshuo is a touristic capital in the middle of the karst formation. Although many tourists pay for an hotel in the town, we decided to stay in a small hotel in the countryside, close to Yangshuo but far enough to have a quiet and pleasant stay. The Moondance Hotel was next to Yulong river, the most beautiful river we have ever seen.
