No motorized vehicles are allowed on the dunes. You can however bring toboggans to slide down the dunes.
There is a 4wd trail that goes around the back side up the pass. That's as much wheeling as you get there. If you are looking for dunes to 4 wheel in look in Walden, Co
I don't think so I'm not that sure because the time that I've gone there I've never seen four wheelers
No, you are not allowed to drive on the sand dunes.
