I'm heading on a short trip to South Korea soon. I will be based in Changwon. I wanted to know how feasible it would be to do a short trip to Wolchulsan National Park. Geographically it's not that far. Is there a direct bus between the two places? Would it be possible to do it in a daytrip? Am I instead better off looking at national parks closer to Changwon, perhaps Gayasan or Jirisan? I would be relying on public transport. Not on a strict budget so short distance taxis aren't too much of an issue if necessary.
Any info is much appreciated,
