The paper presents the results of a ground state study of YGa3(BO3)4 crystals doped with erbium ions. The EPR spectrum of the Er3+ ion, which replaces yttrium ions in a crystal and is located in a slightly distorted prism of six oxygen ions, is detected and decoded. The parameters of the spin Hamiltonian describing the strongly anisotropic behavior of the spectrum are determined g=1.269(1), gbot=9.34(6), A=47.7(5) MHz, Abot=320(9) MHz.
