Ferries to these islands leave from the South Sea Visitor Center (南海遊客中心; nánhǎi yóukè zhōngxīn; daily 6.30am–5.30pm; t 06/926-4738), at 25 Xinying Rd in Magong. Here a couple of private operators offer a variety of tours; weather permitting, these sail daily to Tongpan, Hujing, Wangan and Qimei for around NT$700, leaving at 7.30–8.30am and returning in mid-afternoon – the boats make very short stops at each island. For NT$500 you can visit the first three islands only (skipping Qimei), while NT$350 covers just Tongpan and Hujing. Try to buy tickets in advance.
Otherwise, to stay longer you need to take the public ferry, giving you the option of staying overnight. The ferry departs daily at 9am, arriving at Wangan at 9.45am (NT$278); it departs Wangan at around 10.05am and heads to Qimei (NT$443 from Magong). The boat leaves Qimei at 1.40pm to arrive at Wangan at 2.25pm; it then leaves Wangan at 2.40pm for arrival in Magong at 3.25pm.
