If museums are on your list of things to see, you might want to browse the collections at Taiwan Sugar Museum in Qiaotou District. If you want to see more of the museums in Kaohsiung, Goodbye Lulu-Taiwan Guancun Cultural Park isn't far either.
If you're planning a bit of sightseeing head to Holiu - Bridge of Motherly Affection— just one of the monuments in Nanzi. You could also start your cultural experience by heading over to the art galleries in the area.
Imagine soaking up the atmosphere at Kaohsiung National Stadium, a stadium in Zuoying District. If you think Kaohsiung National Stadium is cool, you also might like Kaohsiung Arena, located nearby.
