We present an omnidirectional matter waveguide on an atom chip. The guide is based on a combination of two current-carrying wires and a bias field pointing perpendicular to the chip surface. Thermal atoms are guided for more than two complete turns along a 25-mm-long spiral path (with curve radii as short as 200 üm) at various atom-surface distances (35–450 üm). An extension of the scheme for the guiding of Bose–Einstein condensates is outlined.
