Wide, deep or long, a canyon is an amazing sight. Wind your way along the trails of Yabakei and be impressed by this geological wonder.
Situated in Nakatsu, this steep-walled valley is well worth including on your itinerary. But you'll find lots more to explore in this area. Rakanji Temple, and Yaba-Hita-Hikosan Quasi-National Park aren't too far from Yabakei.
