you dont....fly is in wyvern hill but the key to it is in solar cave
fly is not there ....... even i dont know where fly is but i can tell you this much
After you beat the game you can go to solar cave you can find keys in there.
Keys can be found on the floor in Solar Cave and Western Cave. They are more frequently found in Solar Cave, though.
You can usually find them lying around Solar Cave itself, but you can also find them in Desert Region. Just check all the floors properly, and you should find a few. There are doors in Wyvern Hill, Desert Region and, of course, Solar Cave. Behind these doors, there is all kinds of treasure, HM's for instance, but you'll have to make sure you've got a Pokemon in your team that can move over water, as the treasure is usually surrounded by it.
after beating Raquayza Medicham will appear in front of the team base so, you have to talk to him then go talk to Lombre in pokemon square then go talk to Wishcash in his pond then in the conversation he'll say something about the solar cave then after talking to him go to the dungeon list and solar cave will appear
