How do Busan and Seoul compare?
The Korean two-city decision — and at 2.5 hours apart on the KTX, most travelers visit both. Seoul is the high-octane capital — palaces (Gyeongbokgung's hourly guard ceremony, Changdeokgung's Secret Garden), Bukchon Hanok Village, Hongdae nightlife, Myeongdong's neon, $5 Korean BBQ at Mapo, K-pop merchandise everywhere, and a metro that connects 25 million people. Busan is the laid-back coastal counterweight — Haeundae and Gwangalli beaches with 80-floor condo towers behind them, Jagalchi fish market where you point at live fish for the upstairs sashimi room, the painted Gamcheon Culture Village hilltop, and a calmer pace built around water and mountains.
Seoul runs $40 hostel / $100 mid / $280 luxe, Busan a touch cheaper at $30 / $80 / $220. Safety in both around 85 — Korea is among Asia's safest countries, and solo female travelers report it as one of the easier places to navigate. English coverage is patchy in both but improving fast (Seoul more international; Busan more local). Seoul wins on cultural sites, nightlife scale, and shopping. Busan wins on beaches (genuine swimming and surfing in summer at Songjeong), seafood (Jagalchi is one of Asia's great fish markets), and a less frenetic pace.
Both peak April-May and September-October. Avoid June-August humidity and the late-summer typhoon window in Busan. Pro tip: take the KTX between them — 2h30, $50, station-to-station. The Busan International Film Festival in early October is the rare time the city outshines Seoul on cool factor. Use a T-money card (works in both cities on every bus and metro) and load it at any 7-Eleven. Pick Seoul as the cultural and nightlife heavyweight Korea trip. Pick Busan to slow down at the coast, or do the standard play — 4 nights Seoul, 2 in Busan, with the KTX gluing them together.
If you have to pick one for a first Korea trip, Seoul is the obvious answer — bigger food scene, more cultural sites, more nightlife, and the country's only must-see palaces. Busan rewards travelers who've already done Seoul or who want a coastal counterweight on a 7+ day trip. Standard split: 4 nights Seoul, 2 nights Busan, with the KTX bullet train as the connector and a half-day Gyeongju detour from Busan for Silla-era temples and tomb mounds.

Seoul

Petty theft is uncommon compared to European cities. The main "risks" are taxi overcharging and the occasional bar scam in Itaewon.

🚇 Getting Around
Busan
Busan has an excellent metro system covering most tourist areas, supplemented by buses and affordable taxis. A T-money card works on all public transport.
Walkability: Moderate — beach areas and Nampo-dong are very walkable, but the city is spread out and hilly. Metro + walking is the best combination.
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.
