Most Taiwan travel guides focus on the Red Line (airport→HSR). But the Orange Line is what actually connects you to Kaohsiung's interesting spots.
**Key Orange Line stations west→east:**
**O1 – Sizihwan (西子灣):** Sunset spot, NSYSU campus (free to enter), good for golden hour photography.
**O2 – Yanchengpu (鹽埔埠):** Pier-2 Art District, old harbor character, good independent cafes.
**O5 – Kaohsiung Arena (巨蛋):** The Arena, Hankyu Arena Mall, Ruifeng Night Market 7 min walk. Great residential base for stays — there are whole-apartment Airbnbs in this area that work well for groups or anyone wanting a local neighborhood feel.
**O8 – Formosa Boulevard (美麗島):** THE transfer station, and also the famous stained glass dome ceiling — worth stopping just to look up. Free.
**O10 – City Council (市議會):** Qingnian Night Market nearby.
**Crucial transfer:** Red ↔ Orange at Formosa Boulevard (O8/R10). Almost every itinerary involves this transfer.
**Fastest connection from HSR:** Zuoying (R14) → direct Orange Line → O5 Arena in **4 minutes**. No transfer. This surprises a lot of people who assume they need to go through the city center first.
The Orange Line alone covers: Cijin ferry access, Pier-2, Formosa Boulevard dome, Ruifeng Night Market, the Arena. One line, all the good stuff.
