We theoretically study the properties of one-dimensional nonlinear saturable photonic lattices exhibiting multiple
mobility windows for stationary solutions. The effective energy barrier decreases to a minimum in those power
regions where a new intermediate stationary solution appears. As an application, we investigate the dynamics
of high-power Gaussian-like beams finding several regions where the light transport is enhanced.
