The disordered medium is modelled by percolation clusters with correlations decaying with the distance as a power law, $r^{-a}$, generated with the improved Fourier filtering method. To characterize this type of disorder, we determine the percolation threshold $p_{\\text c}$ by investigating cluster-wrapping probabilities. At $p_{\\text c}$, we estimate the (sub-diffusive) walk dimension $d_{\\text w}$ for different correlation exponents $a$.
