The sixth gym is in Fuschia City, where you fight Koga, Poison type leader.
If you mean the ones below Fuschia City, then I just flew to Pallet Town and surfed to Cinnabar Island then to Seafoam Islands, completed the gym and surfed back up to Fuschia. By then they let me pass. But im sure there must be a shorter way
This is technically the 5th gym, although you can defeat the 6th gym in saffron city before it.
Surf south of pallet town to get to cinabar island.
In Vermilion City, you go to the gym which is next to the port and you cut the tree. In fact, you don't need to beat this gym for a really long time (you can progress through the game really far before you have to beat this gym) but it helps to beat this gym early because FLY is activated, although you don't get HM Fly until you get to Fuschia City
