It has an area of 105 square kilometers in the tropical zone, with abundant shallow geothermal resources. With 2,623.4 hours of sunshine per year, it is the region with the most abundant solar energy resources in Beijing. Also, Yanqing's wind resources account for 70% of Beijing.[10]

The Yanqing Badaling Great Wall Basin is surrounded by mountains on three sides in the north, south, east, and Guanting Reservoir to the west, namely the Yanhuai Basin. Yanqing is located in the east of the basin, with an average elevation of about 500 meters. Haituo Mountain is the highest peak in the territory, with an elevation of 2241 meters and the second highest peak in Beijing.[11]

Yanqing is surrounded by mountains to the north, east and south, and water to the west, with an average altitude of 500 meters above sea level, and is predominantly mountainous, with mountains accounting for 70% of the county's area.[6]: 104  The forest greening rate of the entire region has reached 74%.[12] In addition, Yanqing is rich in geothermal, solar, wind and other new and renewable energy sources, accounting for 25% of energy consumption, and is one of the first national green energy demonstration counties and a new and renewable energy demonstration area in Beijing.[12]

The highest temperature recorded was 39 °C, which occurred on June 10, 1961.[6]: 65  Prior to 2016 and the lowest temperature recorded was -27.3 °C (-17.14 °F), which occurred on January 23, 1973,[6]: 65  however, on January 23, 2016, the lowest temperature recorded was -29.8 °C (-21.64 °F), the lowest temperature recorded in Beijing in 30 years.[13] The year with the highest precipitation from June to August was 1964 with 747.1 mm, and the year with the lowest was 1965 with 274 mm.[6]: 66  The average annual sunshine in one district of Yanqing County is 2623.4 hours, with an annual sunshine percentage of 60%, the highest sunshine hours and solar radiation in Beijing.[6]: 67

The remnants of a 1,000 year old cliff dwelling community date back to the Tang dynasty are found at Guyaju Ruins near the village of Dongmenying.[24] Archaeologists are uncertain about the origins of Guyaju. One theory holds that the Kumo Xi, a steppe tribe, carved from the rocks the halls and hundreds of dwellings that form a fortress community in the caves.[24][25]

Another historical attraction is the town of Yongning. The town square tower was restored in the 2000s and there is a Gothic Revival Catholic church from the 19th century.[26]

Commune by the Great Wall is in the district.[27]
