Route 507 is a winding road between the arid wasteland of sand, the desert of illusion and the bright and cheery floral park. The air gets much cooler and humid as one exits the wasteland half of the route and grows closer to floral park. Be careful however as the drastic changing climate gives rise to many different types of pokemon depending on which portion of the route you are at. Closer to the desert, expect to find more remnants of the desert pokemon while closer to the floral park, there would be more grass and poison-type pokemon.
