That is correct. You pay at the park, Visa and Mastercard is accepted via a cc payment slip as well as cash. Two park host who are awesome and can get you firewood. The trails in the area are awesome, and the river access is divine. It seems a bit steep $ wise, until you use the showers. Unlimited hot water 7am, to 9pm make it almost worth it, lol. Always have a good time there, and the people that camp there seem to be the mellow types.
There is a pay station. They upped the cost, I think it's like 16 a night.
