Priced at $768 round trip. The route covers 15,339 miles round trip.

Hanoi is one of Asia’s most rewarding city breaks, blending centuries of history with the energy of a fast-changing capital. Its appeal lies in the contrast between the atmospheric Old Quarter’s narrow lanes and traditional shopfronts, the tree-lined boulevards and colonial architecture of the French Quarter, and the calm of lakes and temples that offer a slower rhythm amid the bustle. Visitors come for landmarks such as Hoan Kiem Lake, the Temple of Literature, the Ho Chi Minh Mausoleum complex, and the city’s many museums and pagodas, but also for the simple pleasure of wandering neighborhoods where everyday life still unfolds on the sidewalks.

The best times to visit are typically autumn, from September to November, and spring, from March to April, when temperatures are milder and humidity is more comfortable for exploring on foot. Hanoi’s food culture is a major draw in its own right: this is the place to try pho, bun cha, banh mi, egg coffee, and the city’s lively street-food scene, which is central to local life. Beyond the cuisine, travelers will find a rich cultural identity shaped by Vietnamese tradition, French colonial heritage, and a strong sense of local community, making Hanoi both an accessible introduction to Vietnam and a destination with plenty of depth.
