push all the boulders down the holes with stength,
a hiker on route 42 will give you the tm strength. use that on the boulders
You can't break them. You use strength(hm04)and push them with a Pokemon that knows that move.
just push the boulders on the floor above it into the holes in the ground

Go to the west of the city towards Mt. Mortar. A man will run out he will give you Strength (HM04)
