Lonely Planet review for Kaohsiung Harbour
The opening of the harbour to the public is still a work in progress, but down by Pier 12 (the Love Pier), Gushan Ferry Pier (渡船站) and Fisherman's Wharf (高雄港漁人碼頭; Gāoxióng Gǎng Yúrén Mǎtóu) you'll find walkways, bike paths, cafes and beer gardens. Check at the train station visitor centre about harbour cruises.
The Pier-2 Art District (駁二藝術特區; Bóèr Yìshù Tèqū) is an old warehouse area that was renovated into art studios (following European and North American examples of similar urban-regeneration projects). Exhibitions and concerts are frequently held indoors and out. Check at the visitor centre for a schedule of events.
