American Southwest vs Seoul

American Southwest

The American Southwest spans a huge elevation range — from desert floors at 900 meters to canyon rims above 2,500 meters — so weather varies dramatically. Low deserts (Phoenix, Page) bake in summer (40°C+), while Grand Canyon South Rim and Flagstaff can get snow in winter. Sedona sits in between. The July-September "monsoon" brings sudden, violent thunderstorms and flash floods.

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.

American Southwest

A rental car is essentially mandatory to explore the Southwest. Distances are huge (Grand Canyon to Monument Valley is 280 km; Sedona to Page is 210 km) and public transport between parks is minimal. Once inside Grand Canyon South Rim, however, free shuttle buses efficiently cover all viewpoints. Amtrak's Southwest Chief stops at Flagstaff, and small regional airports serve the area.

Walkability: Downtown Sedona, Flagstaff, Williams, and Page are pleasantly walkable once you've parked. The Grand Canyon Village is very walkable — you can walk the entire South Rim Trail (21 km) past all major viewpoints. Outside town centers, distances and lack of sidewalks make walking impractical.

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.
