Pokémon Diamond and Pearl/Oreburgh Gate

Events

 * Almost immediately, a hiker will walk down and give you HM6, Rock Smash. This HM is not currently usable outside of battle, but that will be resolved after you beat Roark, Oreburgh's Gym Leader. To get to Oreburgh, just go to the right, passing behind the trainers' backs if you like.

Floor 1

 * There is a hiker who will give you HM 6 just to the right of the left entrance.
 * There are two trainers straight ahead, although you may step behind their backs to avoid battles.


 * 1st Trainer (Platinum)- Starley: Lvl 7 & Shinx: Lvl 7


 * 2nd Trainer (Platinum)- Bidoof: Lvl 9


 * To the north, there is a small passageway blocked by rocks. These can be Rock Smashed to reach the lower level.

People

 * There is a biker that explains that the jumps can be only made with a bike.
 * There is a Veteran who will fight you on the ledge across the underground lake.

Items

 * These items can be obtained by using Rock Smash: Stardust and TM70. To get TM70, go down the stairs from the entrance. Go right, use Rock Smash, and the TM is just to the right. To get the Stardust, go to the left from the bottom of the stairs. Rock Smash past three rocks, and the Stardust will be above you and just to the right on a small ledge.
 * This item can be obtained by using Rock Smash and the Bicycle: TM31. To get this TM, go left from the bottom of the stairs. Rock Smash past the three rocks, and use the bike (in fourth gear) to jump the ramps. The TM will be just above you.
 * These items can only be obtained by using Surf and Strength. Surf to the left along the lake. You will reach a ledge with a Veteran trainer on it. Go past the Veteran, then use Strength to push the boulder out of the way to receive a TM01 and an Earth Plate.
