The South Korean city of Busan is home to the world’s largest department store, Shinsegae, which also houses one of Korea’s largest spas, Spa Land, catering for up to 1,500 people at a time. This is not a spa for those with inhibitions because many of the areas within the spa require patrons to be naked. But for those willing to embrace Korean culture and go naked with the locals, a visit to Shinsegae Spa Land might well be one of the most memorable experiences of a trip to South Korea.
