Kalos Canyon
Kalos Canyon (Japanese: カロスキャニオン Kalos Canyon) is located in Route 11, between Geosenge Town and Shalour City. It was formed naturally over the course of tens of thousands of years.
The winds blowing through the ravines in the canyon turn into rising air currents, and as such it's an ideal spot for Sky Battles. There is a center nearby specially for Sky Battles, where Trainers can rent Sky Battle suits and practice in air tubes. The actual Sky Battles are held over the canyon.
