  We prove that every bounded smooth domain of finite d'Angelo type in
$\mathbb{C}^2$ endowed with the Kobayashi distance is Gromov hyperbolic and its
Gromov boundary is canonically homeomorphic to the Euclidean boundary. We also
show that any domain in $\mathbb{C}^2$ endowed with the Kobayashi distance is
Gromov hyperbolic provided there exists a sequence of automorphisms that
converges to a smooth boundary point of finite D'Angelo type.
