Zion in August: what the park service says
In August the Zion Canyon Scenic Drive is shuttle-only, as it is daily from March through November; cars are not allowed on it while the buses run. Start at the Zion Canyon Visitor Center, where the first shuttle leaves, or skip the park lots entirely, which often fill early in the day, by parking in Springdale and taking the free town shuttle to the walk-in entrance at Zion Canyon Village.
