This may be a stupid question but how much per night to camp?

You can't camp on them.

No camping

Any where around this area to camp?

It's kinda on the side of a cliff by a neighborhood. I don't think there's anywhere near there to camp

I have not heard of anyone camping at sunset cliffs. I believe is closes at night.

No

It closes at 10pm - no camping.

You can't camp around there
