Hi Steve. There are plenty of climbers here in Busan that can help you find gyms & gear. It just so happens that I'm going to a climbing shop myself tomorrow morning in Yeonsandong, which is pretty easy to get to from Seomyeon. Can you meet at Yeonsandong subway exit 12 @ 10am? Text me if you can make it. (Cell # in profile)
Your closest gym is probably this one,
but a group of us go to Dongnae wall
or Dae Ryuk Bong
about twice a week, usually in the mornings. Once you get hooked up with shoes/harness you're welcome to join us. What are your working hours?
