I'm planning WAY in advance a rim to rim hike.

I've learned there is a small parking lot (20 to 25 vehicles) at the North Kaibab Trail trailhead (I was told it was actualy about 1/4 mile away).

If the above is not accurate, please advise.

But my main question -- does anyone know if there are any posted parking restrictions at this parking lot? Particularly with regard to overnight or long term parking?
