Hanoi attractions: choosing the sights that fit your days
Hanoi's sights spread across districts, so a sensible plan groups them rather than crisscrossing town. Hoa Lo Prison and St. Joseph's Cathedral both sit in Hoan Kiem district, close enough to pair in a morning, while the Imperial Citadel of Thang Long waits in Ba Dinh and the Museum of Ethnology sits out in Cau Giay, worth a longer block of time.
Some stops reward planning. The Hanoi Opera House has no walk-in hours, so the colonnaded interior only comes with a seat at an opera, ballet or orchestra evening, with tickets from 500,000 VND set per production. The Vietnam Museum of Ethnology explains the cultures of Vietnam's 54 recognized ethnic groups inside, then sends you out among full-scale stilt houses and communal buildings, and a booking is recommended.
Other visits are lighter. St. Joseph's Cathedral is a working neo-Gothic parish with free entry, its doors mostly following Mass times, and the plaza is simple to wander though the midday closure matters for the interior. Hoa Lo Prison packs dense labels into 60 to 90 minutes, and th Citadel's Le dynasty gates, Nguyen tower and wartime bunker sit minutes apart on a 2-3 hour loop.

Where reserving ahead pays off in Hanoi
The Opera House is the clearest case: no walk-in visits exist, so plan an evening around a Vietnam National Opera & Ballet performance and expect from 500,000 VND per production. For the Vietnam Museum of Ethnology, booking is recommended, sensible given the 3-4 hours its indoor galleries and outdoor stilt houses can absorb.
Free entry at a Hanoi church
St. Joseph's Cathedral asks nothing at the door, with free entry and no fee listed. Time your stop outside the midday closure or just before a service to see the stained glass and gilt sanctuary, or simply circle the plaza at 40 Nha Chung Street in 20 to 40 minutes.
