Solo in Beijing for 4 days, the scale of this city is no joke

1.National Museum of China, Beijing

2.Mutianyu Great Wall, Beijing

3.Badaling Great Wall, Beijing

4.Summer Palace, Beijing

5.Temple of Heaven, Beijing

25F, first Beijing trip, just finished 4 days solo. I knew Beijing was big, but 20k+ steps daily did not feel real until I stopped after hitting spots like the Forbidden City and Temple of Heaven and realized my calves were absolutely destroyed. Every attraction in Beijing is massive so definitely wear comfy sneakers. Used app for tickets and audio guides at the Forbidden City, Temple of Heaven, and Summer Palace, saved me a lot of time figuring stuff out solo.

For Mutianyu, Didi in Alipay got me there fine. Felt safe the whole time, even walking back late. Anyone else been to Beijing solo?
