A composition and method for making a simulated rock climbing, including the steps of making a mold for a basic shape for a rock climbing wall casting, filling the mold with cellular concrete; allowing the concrete to cure partially and inverting it in a bed of sand, removing the mold to expose the simulated rock climbing wall casting; sandblasting the simulated rock climbing wall casting into its general finished shape; and using concentrated sandblasting to form integral recesses and protrusions comprising various hand holds.
