A nonlinear theory of the parallel diffusion of charged particles with perpendicular scattering and dynamical turbulence is obtained. The combination of the new parallel diffusion theory and the nonlinear guiding center theory shows good agreement with numerical simulations using typical parameters for a solar wind. Furthermore, the combination of the theories has a simpler mathematical form and is more computationally tractable than the weakly nonlinear theory.
