Minoh Park
A forested valley 30 minutes north of the city with a well-paved hike that ends at a proper waterfall β wild monkeys and deer along the way, fireflies in early summer, and if you're lucky a giant salamander in the river. Best in autumn for the leaves. Pairs naturally with Katsuo-ji Temple as a full day trip, and there are ryokan up in the mountains if you want to stay the night.
