The Kii Mountain Range is made up of a series of soaring, 1,000-meter peaks. This area is home to three deeply spiritual locations, including Kumano, home of nature worship; Yoshino and Omine, a training ground; and Mt. Koya, a foundational site for Japanese Buddhism. Although formed in different eras, and for different beliefs, a 300km pilgrims' path connects all three locations. This verdant and spiritual route is still followed by visitors today.
