An easy day trip from Seoul, Seoraksan is one of South Korea's most famous mountains. Hiking is very popular among South Koreans - most people do not realize that the country is very mountainous. Enjoy flowing streams, modest waterfalls, and other excellent mountain vistas amidst the fall foliage while partaking in this favorite South Korean pasttime, and don't feel bad if an ajema (older Korean woman) barrels past you with her walking stick and sun visor! Insider's Tip: book a budget friendly, English speaking tour of Seoraksan with Adventure Korea, which is very popular with English teacher expats.
