The Yonago Castle Ruins are not to be missed. I found that there was not to much to do in Yonago, but this is well worth exploring. There is a parking lot at the base, and several different hiking trails to the ruins, all were fairly easy. Once at the top you get incredible views of the city of Yonago, the sea, and Mt. Daisen. I bet it would be beautiful here during sun rise and sun set. The ruins itself are pretty impressive, it must have been a huge complex. Definitely, come here for the views!

Really nice view from the top, worth the walk, there are a lot of instructions a long the way. The entrace we climbed up was to the right side of the ruins when you walk from Yonaga station to there, and you pass by a baseball field on your left side, when you reach the corner, you’ll see a street going upwards, just walk up, and follow the path which is behind 3 tenis squares.
