The magnetic ground state of polycrystalline N\'eel skyrmion hosting materialGaV$_4$S$_8$ has been investigated using ac susceptibility and powder neutrondiffraction. In the absence of an applied magnetic field GaV$_4$S$_8$ undergoesa transition from a paramagnetic to a cycloidal state below 13~K and then to aferromagnetic-like state below 6~K. With evidence from ac susceptibility andpowder neutron diffraction, we have identified the commensurate magneticstructure at 1.5 K, with ordered magnetic moments of $0.23(2)~\mu_{\mathrm{B}}$on the V1 sites and $0.22(1)~\mu_{\mathrm{B}}$ on the V2 sites. These momentshave ferromagnetic-like alignment but with a 39(8)$^{\circ}$ canting of themagnetic moments on the V2 sites away from the V$_4$ cluster. In theincommensurate magnetic phase that exists between 6 and 13 K, we provide athorough and careful analysis of the cycloidal magnetic structure exhibited bythis material using powder neutron diffraction.
