There's no bad time to visit the canyon, though the busiest times of year are summer and spring break. Visiting during these peak seasons, as well as holidays, requires patience and a tolerance for crowds. Note that weather changes on a whim in this exposed high-desert region. You cannot visit the North Rim in the winter due to weather conditions and related road closures.
