Kalos Route 2
Kalos Route 2 is the second route in Kalos. It connects Aquacorde to the Santalune Forest.

Kalos Route 3
Kalos Route 3 is seen at the first trailer. If you look at the first trailer and the screenchots from the official website you ca see that this Route looks different from the first trailer, for example having more trees and more detaied plants, rocks, etc. This may be because they are still working on the designs of the overworld. It is most likely the third route of the Kalos region. This Route connects Santalune Forest with Santalune City.

Trivia

 * Similarly, Kalos is the second region to have the routes restart at 1, the first being Unova.
 * Kalos is meant to be based on France, although the creators also took inspiration from other parts of Europe. If you look at the top-left corner of the Kalos region you can see a town with a resemblance to Stonehenge, which is in England, mixed with the Carnac Stones, a group of rocks in France.
 * Route 1 in Kalos is one of the shortest routes in the game.
