Rotorura isn't the kind of city you catch glimpses of looming in the distance. In fact, you don't even need your eyes to sense you're drawing near. Just use your nose. The not-so-subtle scent of sulphur hangs over the countryside surrounding the city while steam rises from any hole in the earth.
In this hotbed of geothermal activity, people are the only ones not allowed to smoke. "No smoking in the thermal valley." Really???
