A first look in 60–90 minutes
Orient yourself at the entrance information, choose the Otani No. 1 reconstruction as your main stop, then add the smaller mounds or the Earth-history bridge. Pause for the view if the designated ascent suits everyone. Return by a familiar, open path rather than improvising a shortcut over a mound. This is an editorial sequence of sights, not a mapped circuit, distance claim or step-free route.
