In these lectures, I will present an analogous Khinchin-type theorem for horoballs packings in Gromov hyperbolic metric spaces that arise from geometrically finite actions with controlled parabolic growth. An application is the logarithm law for cusp excursion; that is, we prove asymptotics for the depth in the horoball packing of a typical geodesic.
