The player first accesses this route from the west, the Hayward City direction. A patch of long grass can be accessed on this route without the player needing to use Cut, which can be useful for training. However, to progress further, the Owsauri CityGym badge is required to Cut down the trees and pass through.
At the east end of the route is Silk Tunnel, a cave with several floors containing wild Pokémon and trainers, so bringing plenty of healing items is recommended.
Route 63 is first reached by the player once they have traveled through Silk Tunnel, and is the way they will go to get to Hayward City and beyond. A Pokémon with Cut is required to leave the route and reach the city.
A colored background means that the Pokémon can be found in this location at that time of day. A white background means that the Pokémon cannot be found at that time.
