The Great Wall in late September

 Clothing: For early September, short-sleeved tops paired with a light jacket and thin long pants work well. By mid-to-late September, opt for long-sleeved T-shirts layered with a jacket or hoodie. For bottoms, sweatpants or jeans are suitable, and it’s wise to pack long johns as a backup. After rainy days, a thicker jacket is recommended.

Shoes: Comfortable, non-slip sneakers are the optimal choice.

Others: Sunglasses, sunscreen, a sun hat, a raincoat, and an adequate supply of food and water.
 1. The night tour service at Mutianyu Great Wall concludes at the end of August. If you wish to experience a Great Wall night tour in September 2025, consider visiting Badaling Great Wall or Simatai Great Wall instead.

2. It is recommended to avoid visiting the Great Wall during the final three days of September. Since China’s National Day Holiday runs from October 1st to 7th, many tourists begin their trips in advance of this period, leading to high demand for train tickets and Great Wall entry passes, which can be difficult to obtain.
