Daimonzaka is the slope that leads up from the valley floor towards Nachi Taisha Shrine, Seigantoji, and the Nachi Falls. Most people now take the modern road.
Daimonzaka means "Great Gate Slope", though the gate has long since disappeared, the path is flanked by huge trees, some 800 years old.
The stone staircase is 600 meters long and comprises of 267 steps. Near the base is shop renting Heian period costumes for cosplay photo ops.
For those unable to walk the Kumano Kodo it offers an opportunity to experience the pilgrimage route. At the top the road heads down to the right towards the Falls or a further series of steps carry on up to the shrine and temple.
