You must go and search for it on routes 116 and 117 and then go to Snowpoint City Gym. Use a Pokemon like Infernape and use Fire and Fighting type moves. Candice ( gym leader) will give you HM Rock Climb at the end of the battle and teach the HM to your Pokemon. I hope this advice helps!
rock climb
You get rock climb at the one of the gyms
Rock Climb is not a move in the game. It wasn't a move until Diamond/Pearl/Platinum, which came out after FireRed.
yes you are
You have to teach them Rock Climb, which is a HM(Hidden Move).
HM Rock Climb
In Pokémon Ash Gray, you can rock climb by obtaining the Rock Climbing ability through your Pokémon. Once you have a Pokémon that knows the move "Rock Climb," you need to find a climbable rock wall, which is usually marked by a gray texture. Approach the wall and select the Pokémon with the Rock Climb move to ascend. Ensure you have the necessary badges to use the move outside of battle.
In Pokemon diamond, pearl, and platinum rock climb is found on route 217. (SEARCH EVERYWHERE)
you find rock climb from one of the gym leaders. easy as that.
