Does my Parking reservation provide entry to all passengers in my car?
No. You will need both a parking reservation and entry ticket for yourself and an entry ticket for the passengers in your vehicle.
I purchased an Entry voucher; where do I park?
There are no parking options outside of Waianapanapa State Park without a parking voucher. The road leading up to the park is privately owned and your car will be towed if you park there!  Valid forms of transportation with an entry voucher are walking, non-motorized vehicles (e.g. bike), rideshare/taxi, or carpooling with a Hawaii Resident with State Issued ID.
I booked the wrong date or time-slot, can you please change my reservation?
Unfortunately reservation dates and times cannot be changed once the purchased. ALL SALES ARE FINAL. No refunds, no exceptions.
If we purchased the 7:00am to 10:00am do we need to purchase another voucher to stay until 12:00pm?
Yes, multiple time-slots can be purchased to stay at the park for an extended period. In this situation a voucher for 7:00am to 10:00am and a voucher for 10:00am to 12:30pm will be needed.
My reservation states the time of entry is 10:00am-12:30pm. Does that mean I have to leave the park by 12:30?
Yes. You can enter the park anytime within your reservation time-slot but must leave the park once your reservation has ended.
Can I park there all day?
If you want to park all day, you’ll need to purchase vouchers for all the time you plan on visiting. If you want to be there from park opening until sunset, you’ll need to purchase all four time-slots. Note – not all time-slots may be available on a given date.
