Although there isn't anything particularly pretty about it, Busan does attract many tourists and is a quickly-growing city thanks to its trading activities (5th biggest port in the world) and tourist attractions. It offers a friendly welcome to the tourists who come here in throngs, and especially Japanese nationals, for whom this is a starting point when they arrive by ferry. From Seoul, the best way to get here is by KTX, the Korean fast train that connects the 2 cities in 3 hours. A 2-day/1-night stay seems sufficient to see the main sights, but you could easily spend just as much time here as in the capital. You might consider a longer stay if you want to familiarise yourself with the Korean way of life. Busan cannot be described as a centre of spirituality since it only has 2 Buddhist temples (Beomosa and Samgwangsa). Instead, it's mostly a city of leisure, surrounded by beautiful landscapes: the island of Eulsukdo, Yeongdo lighthouse and Gwangan Bridge by night. You can stroll among the fishmongers' stalls of Jagalchi Market or indulge in some retail therapy in Seomyeon street at the huge Gukje Market, where you can find absolutely everything.
