$30 per night, full hookups.

$20 dry sites.

Sites are reservable through recreation.gov.

Note:  Reservations are required.  Its best to make reservations prior to your arrival.  However, you may call or use the parks website when you arrive.  Unfortunately, you will need to drive to the top of the hill to get a good internet connection.  Campbase made reservations through the web site and it worked quite well.
