This 90-minute journey covers nearly 20 kilometers, passing through rolling hills, lush forest valleys, and traditional villages. Traveling through 24 tunnels, the approach to this UNESCO World Heritage Site in Wakayama Prefecture promises an epic visual experience. Make sure to keep your camera ready at all times!

Exploring the Serenity of Mount Koya
Upon arriving at Gokurakubashi Station, the journey continues by cable car, which will take you directly to the summit of Mount Koya. This mountain plateau is one of the most revered centers of Buddhism in Japan, home to more than 100 temples scattered across the area.
Here, you can immerse yourself in tranquility by strolling through Okunoin Cemetery, beneath towering cedar trees where rows of stone lanterns illuminate the path leading to the mausoleum of Kobo Daishi. Be sure to also visit Kongobuji Temple, the headquarters of Shingon Buddhism, famous for its gold-leaf sliding doors and the largest rock garden in Japan.
