Seoul vs Siem Reap

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.

Siem Reap

Siem Reap has a tropical monsoon climate nearly identical to Phnom Penh. It is hot year-round with a distinct wet season from May to October. The temples can be brutally hot midday — plan early morning and late afternoon visits.

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.

Siem Reap

Siem Reap town is compact and walkable, but the temples require wheels. Most visitors hire a tuk-tuk or car with driver for full-day temple tours. Bicycles are popular for the Small Circuit temples. The town has no public transit system.

Walkability: The town center around Pub Street, the Old Market, and the river area is easily walkable. Most hotels and guesthouses in the tourist zone are within a 15-minute walk of the center. The temples, however, are 6+ km away and require transport.
