Why trust this guide

Seoul is a city of ten million people wrapped around mountains, where six-hundred-year-old palaces sit two subway stops from neighbourhoods that set global trends in music, skincare and food. It is enormous, immaculately organised, open extremely late, and far easier to travel in than its size suggests.

Why it's worth the flight

Few cities compress this much variety into one metro system. You can hike a granite peak in the morning, eat at a market stall at lunch, sit in a Joseon-era palace garden in the afternoon and be in a fourth-floor cocktail bar at two in the morning. The public transport is among the best in the world and the city is exceptionally safe.

When to go

Spring, roughly April to May, brings cherry blossom and mild weather. Autumn, late September through November, is the local favourite — clear skies and mountain foliage. Summer is hot, humid and includes a genuine monsoon. Winter is properly cold, with temperatures well below freezing, though the city is built for it and the food is at its best.

Where to base yourself

Get the transport card first A rechargeable transit card works on every bus and subway in the city and beyond, and it is the single thing that makes Seoul effortless.

What to eat

Korean barbecue is the obvious one and worth doing properly at a place full of Koreans rather than a tourist strip. Beyond it: bibimbap, kimchi jjigae, samgyetang (ginseng chicken soup), tteokbokki from a street cart, naengmyeon cold noodles in summer, and the whole institution of banchan — the free side dishes that arrive with everything and get refilled. Convenience-store food here is genuinely good, not a compromise.

Getting around

The subway is comprehensive, cheap, signposted in English and runs until roughly midnight. Buses fill the gaps. Taxis are plentiful and metered; the Kakao T app is the local standard. Walking is pleasant but Seoul is hillier than people expect — the city sprawls across and between mountains.

Fly business for less

Long-haul to Asia is where points matter most

The gap between economy and business on a route this long is exactly where miles earn their keep. Here's how ordinary spending gets you there.

The honest caveat

Seoul is vast and spread out; you will spend real time on the subway and should plan by district rather than hopping across the city repeatedly. Language is more of a barrier than in Japan or Singapore outside the main tourist areas — a translation app earns its place here.
