Abstract: In this paper, we show that the level sets of mean zero finite variance random walks in $ {\mathbb{R}^1}$ form a discrete fractal in the sense of Barlow and Taylor. Analogously to the Brownian motion result, the Hausdorff dimension of the level sets is almost surely equal to $ \tfrac{1} {2}$.
