$5 cash only. They only charge on the weekends currently, because of the construction trucks on Calavarous Rd Mon -Fri.
$5.00 per passenger vehicle for parking. It's quite a drive out there. Looks like you're going to uncharted territory. Don't run out of gas! And make sure your car is working well. Bring food and drink as there's (very)limited selection at the museum. And no GPS or phone service way out there! Sorry...tmi!
