Seoul vs Vientiane

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.

Vientiane

Vientiane has a tropical savanna climate with a pronounced wet season from May to October. It is hotter than Luang Prabang due to its lower elevation and flat terrain. The cool season (November-February) is the most comfortable period, though midday temperatures remain warm.

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.

Vientiane

Vientiane is more spread out than Luang Prabang, making walking between all sights impractical. Tuk-tuks, motorbike taxis, and ride-hailing apps are the main options. The city has a limited local bus network and no urban rail system. Renting a bicycle works well for the central core.

Walkability: The central area between Wat Si Saket, Patuxai, and the riverfront is walkable but spread out — expect 20-30 minute walks between major sights. Sidewalks are uneven and sometimes blocked. The riverfront promenade is pleasant for walking. Pha That Luang and Buddha Park require transport.
