Ifs its just the semi you will have room, but if you have trailer hooked up i would suggest to park it at gas station or un-hook it at gas station and drive just the semi with no trailer
There is large gas station down below but quite a walk. I would try going in and park along roadway inside about a quarter mile in. I have seen some park there before.
I believe the park ranger at the gate, would help you find a parking place.
MrM Jimmy is right. The parking lot won't fit a large semi. There are roads around the monument you can drive through. It's amazing
The parking lot is pretty big there and campers were parked inside.
They are car park inside it
