The semiclassical propagation of spin-coherent states is considered in complex phase space. For two time-independent systems, we find the appropriate classical trajectories and show that their combined contributions are able to describe quantum interference with great accuracy. Not only the modulus but also the phase of the quantum propagator, both dynamical and geometric terms combined, are accurately reproduced.
