you need to get the 7th gym badge.

No, because you can't use Rock Climb out of battle without Snowpoint's Gym Badge.
First you need the HM rock climb then somewhere to the left of the suite is a rock wall that you need to use rock climb on and follow the trail of rock walls and you're there.
Its at Route 211, use Rock Smash then Rock Climb.
yes
Professor Oak gives HM08 Rock Climb to you after you get all 16 badges.
You can use it after winning the Glacier badge at Snowpoint city.
You have to beat the elite four then go to Kanto and beat all of their gyms to use rock climb.
I think it's the 7th badge, i just tried it and i have 6 badges and it failed :/
The HM Rock climb can be found on route 217. The icicle Gym badge is required to use Rock climb outside of battle.
ANSWER:Icicle Badge (Snowpoint City)
You will need the 7th badge to use the move Rock Smash.
Beat the gym leader.
As far as I'm aware, you need the badge from Canalave City (the sixth) which can be reached after obtaining the Surf HM from Cynthia's grandmother. Hope that helps! - BanetteBrain
The 7th badge.

In Diamond, Pearl, and Platinum, you will find HM08, the device needed to teach Rock Climb, on Route 217, near Snowpoint City. In order to be able to use the move outside of battle, you will need the Icicle Badge from the Snowpoint Gym. In Heart Gold and Soul Silver, you will need to defeat all 16 Gyms before you can use Rock Climb at all. When you conquer the Viridian Gym, Blue will hand you the Earth Badge, which enables you to use Rock Climb outside of battle. Immediately afterwards, Professor Oak will call you, and summon you to his lab. Speak to him there, and he will give you HM08.
