Hanoi vs Seoul

Hanoi

Hanoi has a humid subtropical climate with four distinct seasons. Summers are hot and humid with heavy monsoon rains, while winters are cool and drizzly. The shoulder seasons of spring and autumn are the most pleasant.

Seoul

Seoul has a humid continental climate with four very distinct seasons. Summers are hot and humid with a monsoon season (jangma) in July. Winters are cold and dry with Siberian air masses. Spring and autumn are short but spectacular.

Hanoi

Hanoi's public transit is expanding rapidly with new metro lines, but most visitors rely on Grab (ride-hailing), walking in the Old Quarter, and buses. The city launched Metro Line 2A in 2021 and Line 3 is under construction.

Walkability: The Old Quarter and Hoan Kiem area are very walkable, though chaotic sidewalks (often blocked by parked motorbikes and street food stalls) force pedestrians onto the road. Beyond the center, distances are long and walking is impractical due to traffic and heat.

Seoul

Seoul has one of the world's best public transit systems. The subway is clean, punctual, and covers virtually everywhere you need to go. Get a T-money card (reloadable transit card) at any convenience store for 2,500 KRW and load it up. It works on subways, buses, and even taxis and convenience stores.

Walkability: Seoul is moderately walkable but spread out. The historic core (Jongno, Insadong, Bukchon) is compact and pleasant on foot. Hilly terrain in some neighborhoods (Bukchon, Itaewon) can be tiring. Use the subway to cover distances between districts and walk within them.
