Pokémon Omega Ruby and Alpha Sapphire/Route 101

'After being given your first Pokémon, your next job is to find Birch's child, Brendan or May. They're not too far away, in Route 103, just north of Oldale Town. You'll meet your first wild Pokémon here, but you won't be able to catch them yet, as you don't have any Poké Balls.'

Let's begin smoothly
First, you must traverse Route 101, a pleasant little lane linking directly to Oldale Town. There's no Trainers here and the wild Pokémon here are all weak (all at level 2-3). You can't catch any yet, but it's still a good idea to defeat a couple and level up your starter to give you more of an advantage against your rival in the upcoming battle. Note that when you can catch Pokémon, all Pokémon in this route have a guaranteed catch rate.

If your Pokémon is too weak to go further, you can go heal your team by talking to your mom.

As there is not much to do here, you'll fast reach the north exit of this little route, which brings you to Oldale Town, another little town on your road to become Pokémon Master.
