Off the Beaten Path
Hanoi Train Street (Narrow Lane with Trains)
A narrow residential lane in the Old Quarter where a fully operational railway runs twice a day within arm's reach of the houses and cafes. The 10-minute window around each train arrival is the whole event: everyone retreats, it thunders past, then daily life resumes. Free, short, and uniquely strange, worth timing right and folding into an afternoon around Hoan Kiem Lake.
