At the unassuming yet storied landmark of Wangyu Gully Intersection, you'll discover the raw beauty of Beijing's outskirts. This is the gateway to Gubei Water Town and Simatai Great Wall, surrounded by rolling mountains that burst into fiery foliage in autumn and transform into a poetic winter wonderland. Pause here to soak in the serenity away from city chaos, and don't miss the rainbow trout at local farmhouse restaurants—a perfect urban escape.
