This route is in a valley. It leads to the next town, and there are cliffs on either sides. Once you have the hm for fly, you can fly onto the cliffs and catch high leveled flying types.

There is an antique shop run by an old man. He sells rare items, but they cost a lot.

There are few Pokémon in the valley, but they're good additions to any team.
