Purple Mountain (Zijin Shan) Summit Ridge Trail

The Purple Mountain (Zijin Shan) Summit Ridge Trail is the classic long walk on Nanjing's main urban mountain, in the Zhongshan Scenic Area of Xuanwu District, Jiangsu Province, China. Access is straightforward: Metro Line 4 runs to Zhongshan Ling station, from which visitors walk to the Sun Yat-sen Mausoleum entrance on Zhongshan Ling Road. Entry to the mausoleum is free but requires a timed reservation made through the official WeChat mini-program, and a passport is used for check-in, so the booking should be completed before the day of the hike. Parking exists near the scenic area, but public transport avoids congestion on weekends. The route is a loop of about 12 km with roughly 450 m of cumulative climbing towards a ridge that peaks at about 448 m. It is graded moderate: the gradient is sustained rather than technical, and there is no serious exposure. The surface is a mix of granite steps, paved forest lanes and earthen paths, with the first section from the mausoleum involving hundreds of stone steps. Most of the route runs under dense tree cover of camphor, plane and pine, which gives good shade in summer and makes the ridge noticeably cooler than the city. Key landmarks include the Sun Yat-sen Mausoleum itself, the Ming Xiaoling area and Meiling Palace, and Linggu Temple with its forested surroundings; short side trips are possible to each. Viewpoints along the ridge look back over Xuanwu Lake and the Nanjing skyline when haze allows. Sensible turn-around points are Meiling Palace for a shorter half-day outing, or Linggu Temple for those who want to finish with a lower-effort descent. Water is available from kiosks and shops near the mausoleum and temple areas, but not reliably on the upper ridge, so a full supply should be carried, roughly 1.5 litres per person. Pavilions and temple halls offer shelter from sudden rain, though there are no refuge huts in the alpine sense. Hikers should expect large crowds on public holidays and weekends, when paths near the mausoleum become congested. Phone-based payment through WeChat or Alipay is the norm for tickets, food and drink, so visitors without a linked account should carry some cash.
