Is there a phone number to contact someone for more information?

No but you can check the website for more info.

So I have a sprinter van. Stayed here one night last spring. Do you recommend I bring a tent to “reserve my spot” for several nights?

Are reservations required to camp at the campground?

Is a disabled access pass equivalent to a Discovery Pass and therefore would make it free to Camp as well?

If you have particular questions, you can try posting it here. Someone might have a n answer.
