The structure and transport properties of YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7</sub> films have been investigated. At high temperatures and low magnetic field the vortices seem to flow along one-dimensional easy slip channels. The regions near low angle grain boundaries, where superconducting order parameter is locally suppressed, can serve as such channels.
