Tour inside the Sion Castle

#Overseas travel If you rent an audio guidebook, the inside of the Sion Castle is very good to tour. Since they also provide Korean guides, 1-2 hours will pass quickly if you listen to them one by one. It's even free with a travel pass, and it's accessible by both cruise ships and trains, and it's also great for eating lunch at a nearby park. See various things, from the servants' rooms to the underground prison and the battle walls.
