We investigate the propagation of spatial solitons in a nonlinear metamaterial formed by metallic nanowires embedded in a Kerr-type material. We show that within an effective medium description, the formation of spatial optical solitons is only possible when the wires are embedded in a self-defocusing medium, and demonstrate that for comparable nonlinear perturbations the confinement of spatial-solitons depends on the degree of hyperbolicity of the dispersion of the photonic states.
