Taiwu Town is easily accessible from Beijing by high-speed rail. From Qinghe Station to Taizicheng Station, there are free shuttle buses available right outside the stations, taking about 10 minutes to reach various stops within the town. Families without cars have no problem. The town was already a bit chilly during the National Day holiday. There are many hiking trails available. We chose cable car number 4 to the top of the mountain, returned to the transfer station, and began hiking Rainbow Valley G3 from the starting point. The entire trail is 2.33 kilometers long with 15 checkpoints. It winds through forests along a wavy route, and we even encountered some squirrels – quite interesting! We continued until we reached the junction with the G4 chipmunk route, which is also the starting point for the mountain bikes. If you get tired here, you can ride down for 150 yuan. There are many curves, and children up to 12 years old can ride independently. If you choose to continue hiking, take the chipmunk route downhill. Don't stay on the paved road the whole way; after a section of paved road, turn into the pine forest path – that's the correct chipmunk route. Continue until you reach the red wooden bridge, then return to the paved road downhill to the starting point of cable car number 9, Nanshanli Hotel, Paston Hotel, and the end point. Rainbow Valley G3 + Chipmunk G4 is a 6km route that takes 2.5 hours. There are very few uphill sections, making it a fun and engaging route. It's not particularly difficult.
