Get ready to witness something truly otherworldly at the "Hells of Beppu," a collection of spectacular geothermal hot springs that are for viewing, not for bathing. You'll wander through a landscape that feels like another planet, with steaming ponds of vibrant cobalt blue, blood red, and milky white. Five of the hells are an easy stroll from each other, while the other two are just a short bus ride away. Be sure to try the "onsen tamago," eggs deliciously cooked in the natural steam, and relax with a soothing footbath.
