Do you need to speak Korean to travel Korea?

No. You can travel Korea comfortably without speaking Korean, especially in Seoul, which is one of the easier non-English-speaking countries to get around. Subway, bus, store and street signage carries English, major tourist spots and hotels usually have someone who speaks some English, and a translation app covers the rest. Knowing a few words is appreciated and makes interactions warmer, but it is genuinely optional rather than required.

Enough to get by in the places tourists spend most time. In Seoul and other big cities you'll find English on signage and menus and English-speaking staff at hotels, airports, big stores and popular attractions. It's patchier with older shop owners, small local eateries, taxi drivers and once you head into the countryside — which is exactly where a translation app earns its keep. So plan to lean on English in the tourist core and a phone in the gaps.

Papago is the standout for Korea — it's Korean-built, handles Korean translation very naturally, and has camera translation for signs and menus plus a voice mode for two-way conversations. Pair it with Naver Map (or KakaoMap) for getting around, since Google Maps walking directions are limited in Korea; Naver Map gives English transit, walking routes and place info. Download both before you fly. They both need data, so an eSIM or local SIM is what actually makes them work from the airport.

Yes, a bit. English coverage on signs and among staff thins out as you leave Seoul — you can notice it already around Incheon and Gyeonggi and more so in smaller towns and rural areas. Nothing about it is unsafe or impossible; it just means you'll rely on Papago and Naver Map more, and for deep-history sites, the DMZ or regional day trips a Korean-speaking guide removes the friction entirely and adds context you'd otherwise miss.

A tiny set goes a long way and is warmly received: 'annyeonghaseyo' (hello), 'gamsahamnida' (thank you), 'juseyo' (please/give me, handy when ordering), 'eolmayeyo?' (how much is it?), and 'hwajangsil eodieyo?' (where's the bathroom?). Learning to read Hangul — Korea's alphabet, which is famously quick to pick up — is the single highest-value extra, because once you can sound out signs and menus the whole trip feels easier. None of it is required; it just smooths the edges.
