Gueishan Sports Park (龜山運動公園) is a city park next to the Linkou Chang Geng Hospital (林口長庚醫院). The park includes a small, scenic lake with fish, turtles and wading birds, as well as tennis courts. It’s a great place for hospital patients and visitors alike to get outside for some fresh air, sunshine, and exercise. This cache is located in the northwest corner of the park.
