Pokémon Diamond and Pearl/Route 208

Route 208 connects Mt. Coronet to Hearthome City. On the left side of the route, you will find a scenic waterfall. When you hit the grassland, you will find the unique Berry Master, another Pokétch app, and an item to get a rare Pokémon later on.

Route 208

Fresh air

Coming right out of Mt. Coronet you will be on a waterfall and you have to cross bridges to get back to the grassland. Before you do, there are some trainers and items that you will find around the waterfall.

Walk out and cross the first bridge to face Hiker Robert. Take the bridge that goes up and you'll find Black Belt Kyle. Go down the stairs after Kyle to get an X Speed (DP). Go back towards Hiker Robert and go over the bridge that goes right to find Hiker Jonathan. Continue going up the path to find breakable rocks to you left and smash them to go down the stairs to pick up the Poké Ball (DP). Go back up the stairs and down the next stairs and you will see next two trainers, Aroma Lady Hannah and Artist William. You will also see the Berry Master's House to above you so go inside and take a look.

When done in there, go to the berry patch to to the left to get 2x Pinap Berries, 2x Bluk Berries, 2x Razz Berries, and 2x Nanab Berries. After that, go to the bottom part of the grass patch and you will see a Black Belt to talk to receive an item called an Odd Keystone which can be used later on Route 209 to catch a rare Pokémon. In the bottom left corner of the grass patch in a bare spot is a hidden Honey (DP).

Go to the right and you will reach Hearthome City.

Note: The last two trainers on this route either require Rock Slide or Surf so come back here later if you want to face them.
