I'm trying to find a route to take to the Jarasum International Jazz Festival that is happening this weekend, yet am having a difficult time.  Would anyone know if there is a bus or train that would take me directly to Gapyeong from Busan or would I have to go to Seoul and transfer? Also, is there a car rental agency you may find reliable and affordable, as renting a car may be a better option.  

Thanks for the help!
