Transport properties of 10μm to 30μm wide grain-boundary junctions ion-etched in thin colossal magnetoresistance La_{0. 7}Sr_{0.3}MnO_3 films deposited on a SrTiO_3 bi-crystal were investigated. We have measured the current-voltage characteristics in the temperature range from 4.2 K to 300 K without applied magnetic field, as well as the magnetoresistance at magnetic fields up to±10 kOe directed parallel to the film surface, both perpendicular and parallel to the direction of current flow through the junctions. The investigated junctions have nonlinear current-voltage characteristics in this temperature range and consist of several magnetic domains. The maximum magnetoresistance (R(H)-R _{max})/R_{max}, measured at 1 kOe was -17.6% at 4.1 K.
