Xianghu Lake (Xiaoshan)
湘湖（萧山）
A restored lake in Xiaoshan with a 15.4 km greenway system, a 7.6 km seven-colour loop around its Phase-3 basin, 108 bridges and a paid beach. The metro stops five kilometres short, and the loop is the one part a walker can use without a car, in a district with no other trail.
Xianghu 湘湖 is a 6.1 km² lake on the southern edge of 萧山区, restored in three phases. Phase 3 opened on 1 October 2016 and added a 2.9 km² basin, completing the water body you see today. The resort around it became one of China's first national tourist resorts in 2015, and the lake now carries 108 bridges and a 21 km ring road for vehicles. The greenway system is a separate object: 15.4 km in all, made of 7.8 km of Phase-1/2 riding paths and the 7.6 km Phase-3 七彩绿道, the seven-colour loop this site covers. The 14 km figure that appears in older sources is the sum of the Phase-1 and Phase-2 loops, not the riding-path mileage; 7.8 km measures the paths, 14 km measures two loops. The 7.6 km Phase-3 surface is 4.6 m wide, laid in seven colours at roughly a kilometre per colour, free to use, and was named one of Hangzhou's most beautiful greenways in 2019. The 8.175 km hill-path system on 越王城山 and 西山 is a different outing. The lake is often called the West Lake's sister, or Hangzhou's second lake; the comparison is useful once, and the numbers are more useful.
