You'll need to teach a Pokemon the HM Rock Slide, which is located on Route 217, and then press A on the rocky wall and the Pokemon will slide up or downwards of it.
Use TM80 (Rock Slide) on it.
Of course!
Infernape
You don't.
A move tutor in the Battle Frontier will teach one of your Pokemon Rock Slide. It costs 48 BP to do so.
There is no rock climb in pokemon saphire, but there is a rock climb in pokemon diamond and pearl.
Rock Slide is not a TM in Leafgreen. In Leafgreen Rock Slide is a Move Tutor move and the Move Tutor is hidden somewhere in Rock Tunnel.
there is no naval rock in pearl only in emerald, firered ,leefgreen
If you're referring to a stone used on rock pokemon to get them to evolve, there is no such thing.
