Pokémon FireRed and LeafGreen/Route 19



Route 19 is just south of Fuchsia City and is full of trainers and Pokemon. If you're in a hurry, you can fly to Pallet town and take Route 21 to Cinnabar Island instead, but you'll miss out on lots of XP and a chance to catch one of the Legendary Bird Pokemon on the Seafoam Islands.
