Route 14 is the next step after beating Clemont for your 5th badge at Lumiose City Gym, unless you want to run around the biggest city in the game. It leads to Laverre City But your friends will be waiting there, and you can get there any way you like in Lumiose City, even by taxi.
The most notable thing on Route 14 is the Scary House. It is before the entrance to Laverre City.
