Yoro is a great day hiking destination especially in the intermediate seasons like spring and autumn. It’s located in the mountains where it’s nice and cool. To get there, one must take the Kintetsu train (from Nagoya), and change at Kintetsu Kuwana. Then take the yellow train of the Yoro Tetsudo company, which is probably on the same platform, but different track to the train you get off of. Then check with the station guard and maps on how to get to Yoro Park. Find your way to and through the car parks and follow the crowd.
Hiking paths at Yoro are unfortunately asphalted, and so there’s no chance of getting lost or falling down an abandoned gold mine, but you need to watch out for the occasional car. However, there are some short sections that a treacherous for those adventuring in high heels, but thankfully the wilderness sections short. The main attraction of Yoro is the water fall and its water. The water fall is nice to reach, but nothing special to photograph. Local legend is that the water can make you look and feel younger (Wikipedia). The local water is sold sugared, fizzed, and bottled, or just still.
Photos should soon be available on the Asia Photo Connection website.
