Photonic spin Hall effect in transmission is a transverse beam shift of theout-coming beam depending on polarization of the in-coming beam. The effect canbe significantly enhanced by materials with high anisotropy. We report thefirst experimental demonstration of the photonic spin Hall effect in amultilayer hyperbolic metamaterial at visible wavelengths (wavelengths of 520nm and 633 nm). The metamaterial is composed of alternating layers of gold andalumina with deeply-subwavelength thicknesses, exhibiting extremely largeanisotropy. The angle resolved polarimetric measurements showed the shift of165 $\mu m$ for the metamaterial of 176 nm in thickness. Additionally thetransverse beam shift is extremely sensitive to the variations of the incidentangle changing theoretically by 270 $\mu m$ with one milli-radian($0.057^\circ$). These features can lead to minituarized spin Hall switches andfilters with high angular resolution.
