There are so many places you can enjoy autumn red leaves in Kyoto. But here are some recommendations.
It is just one stop from Fushimi Inari shrine by JR train, or you might want to walk from Fushimi Inari to Tofukuji temple.
It is a bit off the center, but try visiting the philosopher’s walk or Shinnyodo as well.
It is just next to the Arashiyama bamboo forest. You can enjoy the green of bamboo, and red & yellow leaves in the temple. There is admission fee to get in there but worth it.
Huge park in the center of Kyoto city. Nice strolling around the park.
It is near Yasaka shrine, in Higashiyama, Gion area. Make sure visiting the park while you walk around the area.
