POKÉMON PLATINUM / GUIDE
Platinum caves and optional dungeons
Find the main rewards and access requirements in Sinnoh’s caves, ruins and side paths.
Edition covered
Original Nintendo DS release; not Brilliant Diamond or Shining Pearl.
Match the entrance to the objective
Several landmarks have separate entrances or later branches. Use the location directory beside this checklist.
Early and middle journey
| Location | Purpose / access |
|---|---|
| Oreburgh Gate and Mine | Early field-move access and story meeting; deeper Gate rewards require later moves. |
| Wayward Cave | Hidden entrance under Cycling Road leads to Gible and the basement bicycle path. Platinum removes the Diamond/Pearl Strength barrier there. |
| Old Chateau | Eterna Forest side trip after Cut; the TV encounter for Rotom is at night. |
| Solaceon Ruins | Unown letters, items and Platinum’s Defog HM. |
| Iron Island | Riley escort, Riolu Egg, Strength from Riley and the mine’s items. |
| Fuego Ironworks | Surf branch with floor panels, items and shard-related exploration. |
Late and postgame branches
| Location | Purpose / access |
|---|---|
| Mt. Coronet | Story climb and later special evolutions; Feebas fishing uses restricted tiles. |
| Victory Road | League route; a postgame branch with Marley leads toward Route 224. |
| Turnback Cave | Find three pillars before reaching thirty rooms; access Giratina’s later opportunity and the Distortion World portal. |
| Stark Mountain | Battle Zone Galactic conclusion with Buck, followed by Heatran. |
| Snowpoint Temple | Bring Regirock, Regice and Registeel for Regigigas; temple entry follows postgame permission. |
Carry the right field moves
Check badge permissions before a long detour. A new field move often makes old routes worth revisiting. Keep a free party slot before collecting an Egg, and save before a one-time gift or legendary battle.
