Going to the Ya'an Panda Base, by the way, Bifeng Gorge, I have to say that Bifeng Gorge will be a pretty good summer resort, especially close to Chengdu. My friends and I like to hike, but the time is a bit insufficient. I only chose a long section of the canyon 7.5 kilometers. The slope in the canyon is not big. It is very smooth to hike along the stream. There are guardrails along the way, which feels very safe. The canyon has several waterfalls all the way. Bailongtan Waterfall has a quite large gap here. The waterfall is very tall, almost nine levels and ten levels. The winter water volume is small and it is spectacular enough. The signs along the canyon are very clear, and even if you walk alone, you will be relieved.
