The Badaling section of the Great Wall is one of the most popular and well-preserved sections, making it a must-see for visitors to Beijing. While some sections have been renovated for easier walking, accessibility can still be challenging due to steep inclines and uneven surfaces; consider the cable car for easier access. Exploring independently is possible, but guided tours offer historical context and navigation assistance. Peak season (spring/fall) sees large crowds; winter can be cold but less crowded. Expect to spend approximately 2-4 hours exploring, with costs including entrance fees (around $7-$10 USD) and transportation. Dress comfortably with sturdy shoes, and bring water, especially during warmer months.
