The best season to climb the Badaling Great Wall is autumn, especially from mid to late October to mid to early November.

In autumn, the scenery of Badaling Great Wall is the most charming. At this moment, the sky is clear and the clouds are sparse. The autumn wind is refreshing. The trees on both sides of the Great Wall are ablaze with colors, and the red leaves are like fire, complementing the ancient Great Wall and forming a splendid and colorful picture. Especially in the section of the city wall between the North Tenth Tower and the Eleventh Tower, the red-leaf trees are mainly Acer truncatum. The pentagonal leaves combined with the geometric outline of the city wall’s crenments make the Great Wall look magnificent and imposing.

Besides, spring (April to May) is also a good time to climb the Badaling Great Wall. At this moment, all things come back to life. The flowers, grass and trees at the foot of the Great Wall sprout and blossom, presenting a scene full of vitality. However, compared with autumn, the weather in spring may be more changeable, and the red leaf landscape is not as spectacular as that in autumn.

Although summer (June to August) and winter (December to February of the following year) also have their own unique charms, the hot weather and large number of tourists in summer may affect the visiting experience. In winter, the weather is cold and there may be snow and ice on the Great Wall, which poses certain safety hazards.

Therefore, taking into account factors such as weather, scenery and visiting experience comprehensively, autumn is the best season to climb the Badaling Great Wall.
