About Diamond Head State Monument Reservations

Aloha and welcome to the official website for the Diamond Head State Monument Online Reservation System. From this website you will be able to reserve and purchase parking (if necessary) and entry tickets to the park.

During the initial release, reservations may be made up to 14 days in advance, but will be extended to 30 days in the near future – please check before your trip to assure the reservations window has not been extended. Because the park gets busy at certain times during the day and may sell out, please book your reservations as soon as possible to avoid missing out.

Please arrive within the first 30 minutes of your reservation period. If you arrive after 30 minutes into your reservation period, you may be denied access and/or parking. There will be no refunds for no-shows or late arrivals. If you purchase parking reservations, be aware that you must exit the park by the end time of your reservation period. This is to accommodate those arriving in later timeslots, as parking in Diamond Head is very limited.

Parking and entry fees must be purchased online, at this website. Persons without a reservation will be turned away.

*State of Hawaii residents are exempt from the fee/reservation requirement – proof of state residency is required at time of entry. Visitors accompanying State of Hawaii residents to visit Diamond Head State Monument are not exempt from the entry fees and must purchase in advance.

*Any commercial carriers or tour companies caught trying to use the visitor reservation system instead of the PUC reservation system may be banned from the park for up to one year.
