From Bulbapedia, the community-driven Pokémon encyclopedia.
Route 31 (Japanese: 31ばんどうろ Route 31) is a route in central Johto, connecting Route 30 and Violet City. The western entrance to Dark Cave is located on the eastern part of the route.
Route description
This route is the third route that Trainers starting in New Bark Town will arrive at. Like the route before it, Route 31 contains more than an even share of ledges that players need to go around to get to Violet City, but may jump over on their way back. A small pond is north of the route, just west of Dark Cave. Featuring few Trainers and a small area, all that a traveling Trainer really has to look out for on this route are the wild Pokémon.
There is a man who seems to be in a sleep-like state that is located next to the pond. He doesn't actually do anything when first encountered, but will be useful later on in the game. At the gate on Route 35 leading from Goldenrod, there is a guard who will give the player a Spearow with Mail attached to deliver to this man. However, any Pokémon holding the mail will suffice, and in Generation IV he won't keep a Pokémon he "doesn't know". After he receives the mail, the man will give the player TM50 (Nightmare) as a reward in Generation II or TM44 (Rest) in Generation IV.
