If you’re in Kyoto in autumn, one of the must-see places is the Kyoto Botanical Garden, which is sometimes called the Kyoto Prefectural Botanical Garden. It has around 12,000 different species of plants with around 120,000 different plants in total.
That might make it special, but it isn’t inherently what makes it worth visiting. And that is the changing leaves in autumn. This is called koyo in Japanese and is a fairly big thing. The Botanical Garden is a fairly big space with quite a lot of trees, and it looks really nice in autumn.
The Kyoto Botanical Garden is actually one of the easiest places to reach by subway in Kyoto; simply take the subway to Kitayama station and get off at exit 3, and it is right there. Admission is 200 yen for adults and 150 yen for high school students, with middle school students free.
