The roads are completely toll free and shouldn't be closed at night. You do need to reserve and pay for campground spaces though if you plan on setting up tents or trailers.
No fees, unless maybe you use a designated camp site.
There is no fee to enter the park at night. There is a fee if you want to camp.
Should be free
It's free to enter any time. Would be wonderful to check out the stars at night with all the wide open skies!
Easy access. Pretty much free just to go there. Camping has a fee.
