Where do you get rock climb in pokemon white?

Answer 1

It's not an HM first of all

Venipede learns it at level 40. Whirlipede learns it at level 46. Scolipede at level 50. Scraggy at 45. Scrafty at 51. Ferrothorn from heart scale. Druddigon learns it at level 49

For further information, Sandshrew, Rhyhorn, Zigzagoon, Bidoof, Gible, Drilbur, Sandile, and Bouffalant can learn it as an Egg move (from male scraggy and scrafty that knows rock climb)

Geodude, Onix, and Ferroseed can learn it as an Egg move (from male ferrothorn that knows rock climb)

Rhyhorn and Gible can learn it as an Egg move (from male druddigon that knows rock climb)

Finally, GLigar, Venipede, Joltik, and Durant can learn it as an Egg move (from male venipede, whirlipede, and scolipede)
