Nagatoro Gorge
A river gorge of naturally sculpted red and green rocks (Hitsujiyama Rhyolite) carved by the Arakawa River — officially designated Japan's first Special Natural Monument (1941).

Local Tips
The traditional wooden boat ride through the Arakawa River gorge (30 min, ¥1,600) is guided by experienced boatmen who use poles to navigate the rapids. The gorge walls of folded metamorphic rock are geologically extraordinary. The Hodo-san cable car above the gorge gives aerial views. Combine with Chichibu Shrine for a full Saitama mountain day.
