No longer free. Costs about $6 and requires a booking. Has an office by the entry with someone to check you in.We showed up at a peak period and it was booked out, though the wet weather had cleared out most people and it was fairly empty. The staff were very helpful, but the booking system is clearly flawed as we had too book for two weeks away in order to pay the site fee even though the camp was empty.This is a an amazing spot though. Can't wait to go back.
