  We assume the validity of the Bekenstein-Hawking entropy, as given in terms
of the horizon area of the Bardeen regular black hole, and consider it as the
fundamental thermodynamic equation. We derive and investigate the behavior of
the main thermodynamic variables. Using the formalism of
geometrothermodynamics, we derive the geometric properties of the corresponding
equilibrium space and show that the curvature contains information about the
stability properties and phase transition structure of the black hole.
