Primitive sites don’t have hookups but many sites have 30A and 50A hookups. The site reservations calls this out clearly.

Some sites do.

Yes and No. Some sites have electric. Others you can elect to be at a primitive site for less money.

There are, but not at every site. And their generator hours are very limited in the morning and evening. It can get very hot there and we camped there one time when we didn’t have electricity and it was not fun with the heat and limited generator hours.

Yes, limited to some sites. Book early.

There is a section where there are full hookups but only about a dozen spots. The others are dry spots but they have a dump station and allow generators until 10. I heard they are trying to add more full hookups though.
