Nice video.
Scubawise, we always stay at this CG. Full hook up. Right outside the gate of Mt. Zion. You can just walk to the gate.

They also have a CG inside. Electric hook up only.
To go around Zion Stops and to get to the Narrows, you will need to take the park shuttle at this time. I believe you have to make reservation for the shuttle during peak hours.
Beautiful NP. We go there at least every 3 months.
