The outdoor lifestyle industry is insanely popular in Korea, second only to the US (or so I read). I suppose it makes sense – Koreans do love gearing up in expensive technical clothing for any/all outdoor activity to include leisurely strolls along the river and weekend trips to the department store. Koreans also enjoy grilling and eating outside or day camping in sweet tents in parks or on beaches. Basic tent camping (as in a tent that sleeps less than four) and backpacking/minimalist camping however is not as widespread.
Instead, Koreans have glamping.
