The City also lists Christmas Day and New Year’s Day closures. Check special notices before relying on the regular schedule. Read the official City guidance.

Know the admission costs

The City lists US$25 entry for nonresidents age 13 and older, plus a 2.35% online payment fee. Nonresident vehicle parking is US$3, paid on-site in cash. Children 12 and younger enter free; other exemptions have eligibility conditions. Check the official page and checkout for your party’s total.

Prepare a fallback that does not depend on entry

Keep the rest of that day flexible until you have a confirmation. A standalone ride does not include admission unless the booking expressly says so. Neither a ride nor an entry reservation guarantees parking. Save your confirmation and make sure the named visitor can provide matching photo ID.

A release time is a chance to reserve, not a promise of availability. Do not schedule your only possible visit for a day with no alternative. Check any transport provider’s cancellation terms before paying.

The planner shows the release in HST and your browser’s local timezone. Make sure your device timezone matches where you will be when booking.

Admission with transport has a different window

The City also links admission with round-trip transportation packages from Waikiki and Ala Moana that can be booked up to a month ahead. The two-day, 7 a.m. rule on this page applies to admission-only bookings. A standalone ride includes entry only if the booking explicitly says so. Compare the package inclusions and final price before choosing.

Before you book

Can I book on Monday for Wednesday?

Yes. That is the City’s published two-day pattern, even though the preserve is closed on Monday.

Is entry guaranteed if online slots sell out?

No. The City describes limited walk-in or drive-in access, but you should not rely on getting a place.
