I believe it'll be open & no reservations needed. Parking is $3/hour. If you plan to stay more than 3 hours, just pay $10 for the whole day.
Yes you can walk in no advance booking necessary! There are lovely creeks and picnic spots all over and just have to pay for parking, and make sure you take out what you take in!
You can walk in to the park. It has a ranger booth. Parking for the whole day is $10. Hourly is $3 per hr. They also have pay machine. At least walk to the rock pool and visit visitors center.
Yes it will be open
