Summer is the best time to visit Inner Mongolia Autonomous Region in north China, and the region's grasslands in particular are a big draw. The Hulunbuir Grassland, for one, welcomed more than 6 million tourists in July, hitting a record high. Apart from riding a horse and spending a night in a traditional Mongolian ger, visitors now have more fun activities to choose from, including river drifting, paragliding and go-karting.
