Road 12 and Coumarine City | Walkthrough Pokemon X/Y Guide

Once here, Your rival will appear and HM03 - Surf. It's a move that lets You cross water. Teach it to a Water-type pokemon, and proceed. Once You cross the water, head east, then north to the next city. Head east until You find the train station. You'll meet Prof. Sycamore, who will give You a HM for Flying (thanks to which You will gain and an ability to fast travel to known cities, pretty nice, eh?). Talk to the clerk in the station building. Use the monorail. Once in the other part of town, head east for the gym, inside a cave. The Coumarine gym is a Grass-type. Follow the ropes to get to the upper areas. On the top the Leader awaits. As You may already know, Fire is Grass-types natural born enemy. Burn the opposing monsters with ease. If You don't have a Fire-type, Flying will also do the trick. You know what to do. Congratulations, You're halfway through the Gym Leaders. On to the next one. Head south for the unlucky Road 13.
