Spot guide
Sanxiantai refers only to the mainland recreation area: the bridge closure is not a mainland closure. Xiaoyeliu is usable only for a published, booked night session that proceeds.
Sanxiantai mainland and Xiaoyeliu share a Highway 11 trip, but the first is a general-access mainland area and the second is usable only in a published, booked night programme that proceeds.

Taitung City or Chenggong
Plan the drive and return between Taitung City and Chenggong. Sanxiantai directions stop at the mainland parking/recreation area; Xiaoyeliu directions stop at the visitor-centre event meeting point.
Highway 11 coastal drive comparing general access with a reserved session
Sanxiantai's eight-arch bridge is closed through the end of 2027 while the mainland area remains open. Xiaoyeliu's daytime visitor hours do not grant independent night entry.
Checks before departure
A public planning option still needs a user recheck of coastal warnings and roads before travel. A booked Xiaoyeliu session remains ineligible until its date and operation are confirmed.
Sky conditions only
Give your eyes about 10 minutes to adapt to the dark after arrival. Keep flashlights and vehicle lights low for other stargazers.
