We discuss the properties of Lorentzian wormholes in dilatonic
Einstein-Gauss-Bonnet theory in four spacetime dimensions. These wormholes do
not need any form of exotic matter for their existence. A subset of these
wormholes is shown to be linearly stable with respect to radial perturbations.
We perform a comprehensive study of their domain of existence, and derive a
generalised Smarr relation for these wormholes. We also investigate their
geodesics determining all possible particle trajectories, and perform a study
of the acceleration and tidal forces that a traveler crossing the wormhole
would feel.
