How do you get to flannery in Pokemon emerald?

Answer 1

After entering the gym, head left and pass the first warp-thing. Enter the warp to the north. Head south and around the wall to the left. Enter the nearest warp (the two that are only separated by a single space are both trainer battles) after going around the wall. Now head south and jump the ledge. On the left side of the wall, there are six warps (the three right-most holes are trainer battles). Enter the northwestern warp. Now head to the warp directly above you (the one to the right is a trainer battle). Now in the room with four warps, the northeastern one is a trainer battle and the one closest to it is the one you want to take. Now go east and enter the closest warp. The current southeastern warp is the target this time. Go south and jump the ledge, entering the next warp. You made it!
