The World Heritage site of Hieizan Enryakuji is a temple that you can visit while also enjoying a mountain-climbing trek. While appreciating the stone statues and singing birds encountered along the route, even a trekking beginner can reach Enryakuji in around one and a half to two hours.

Taking the “Honzaka Route” comes highly recommended, which is the representative route for trekking on Mt. Hiei.

Get off at Sakamoto Hieizanguchi station on the Keihan Line, and walk for around five minutes to arrive in front of Hiyoshi Taisha shrine. The stone steps next to the torii gate at Hiyoshi Taisha mark the entrance to the Mt. Hiei trekking Pilgrimage route.
Honzaka was once the main path used by those coming to worship at Hieizan Enryakuji, but with the opening of the cable car, the route has seen far less use and is not especially well maintained.

You will proceed up some stone steps, passing the Flower Picking Hall and Turtle Tower, before finally coming to Enryakuji Hall. While there are no signposts along the way, you can’t fail to reach Enryakuji on this easy-to-follow route.
Why not try walking the path like an ascetic monk for the day?
