Boston vs Seoul

Boston

Boston has a humid continental climate with four sharply defined seasons. Winters are cold and snowy, summers are warm and humid, and spring and fall can be glorious. Proximity to the Atlantic moderates extremes but also brings nor'easter storms in winter and occasional sea fog in summer.

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.

Boston

Boston's MBTA — simply "the T" — covers the city with subway, trolley, commuter rail, bus, and ferry. The subway is the oldest in the Americas, compact, and perfect for most visitor itineraries. A CharlieCard (reloadable) or CharlieTicket (paper) is used across the system. Driving is painful — narrow one-way colonial street grids, no numbered system, and notoriously aggressive drivers.

Walkability: Central Boston is one of the most walkable areas in the US. Beacon Hill, the North End, Back Bay, Downtown, and the Waterfront are tightly packed and best explored on foot. The Freedom Trail is literally a walking itinerary. Cambridge is also very walkable once you cross the river. Winter ice is the main challenge; summer heat rarely stops walking.

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.
