Nijo Castle is another World Heritage site in Kyoto. You can read about it here. It was really cool! There is a lot to see as the property is quite large. We rode a bus from the Kinkakuji temple to the Nijo Castle. The bus was super crowded! We were warned about that, but there was literally NO ROOM left on that bus but people kept boarding. After being smooshed on the ride, it was nice to walk around the castle. You aren't supposed to take photos inside the castle.
