How do you get to verdanturf town without rock smash on Pokemon sapphire version?

You have to work your way to Mauville City, which is later in your quest. From there, you can go east and through a small route, and end up in Verdanturf. [ edit ] You have to go to Mr. Briney's house outside of Petaltown's forest. Then ask him to sail you to Dewford.
