Jinqiao Leisure Sports Park is a nice little public park shaped like a strip that is a bit more than a kilometer long between YangGao Middle Road (杨高中路) and LanTian Road (蓝天路).
The park is a serene neighborhood park in the Jinqiao area, with a lazy river running through the strip. The entrance is on LanTian Road, but there is also a small pedestrian gate/entrance on YangGao Middle Road. There are many ball courts, walkways and even a skateboard area in the park, and therefore there a lot of muggles with children. Normally, there is an exceptionally high amount of muggles in the evenings and weekends.
Nearby, there are many restaurants on the Lantian Road side, and the area is across the street from the Jinqiao Leisure center and Carrefour. There are a lot of different cuisines and shops inside the Leisure center, should you want to check that out.
The cache is a 35mm container that is located close to the river next to some large rocks. Sometimes people rest on these rocks, so if there is somebody there on the rocks please wait a while before searching. The cache is not under anything, and you do not need to look around the rocks for the cache. Refer to the hint and spoiler if necessary.
As always, be stealthy when searching and replace the cache back to where it was carefully. Make sure it does not fall out of position and is out of plain sight.
Happy Searching!
