蘇東隧道(Su-Dong Tunnel)in Yilan is a dramatic seaside rail tunnel beside the Pacific. Photographers come for moody, long-exposure shots where waves, mist, and train/walkway geometry frame light beams through the opening. Best light is late afternoon to sunset; weekdays reduce crowds. Access is via Su’ao/Sudong Village roads; there’s usually roadside parking nearby—arrive early for clear access.
