One of the best reasons to get out into the countryside surrounding Beijing in late September-early October is to see all the fantastic colors as the leaves change. The Jiankou Great Wall is a great spot to usher in fall, and is where the inner and outer lines of Beijing’s Great Wall join, wrapping around the ridge lines that surround Xizhazi Village. There are numerous options for varying wall hikes here and many of the trails that lead up to the wall pass through forests of deciduous trees, making for a colorful climb.
