Can you visit Diamond Head without a car?

Yes. TheBus Route 23 runs from Waikiki directly to Diamond Head State Monument, as does rideshare drop-off. Walk-in visitors book an entry-only reservation at $5 per person with no parking fee. This is also a practical option because parking inside the crater is very limited and fills early.

Do you need reservations for Diamond Head?

DIRECT ANSWER

Yes, reservations are required to visit Diamond Head State Monument if you are not a Hawaii resident. The Hawaii DLNR launched the online reservation system in 2022 to manage overcrowding after a record 6,000 hikers showed up in a single day in 2019.

All non-resident visitors must book in advance through the official state portal at gostateparks.hawaii.gov. Walk-in entry is not allowed — if you arrive without a reservation, you will be turned away at the gate.

Entry costs $5 per person for non-residents. If you are driving, parking inside the crater is an additional $10 per vehicle and also requires a reservation. Hawaii residents with valid state ID are exempt from both the fee and the reservation requirement.

Reservations open 30 days in advance at midnight Hawaii Standard Time. You must arrive within the first 30 minutes of your booked time slot. Late arrivals may be denied entry, and no refunds are issued. The park is open daily from 6:00 a.m. to 6:00 p.m., with last entry at 4:30 p.m. Always check gostateparks.hawaii.gov for any closures or updates before your visit.

PRACTICAL TIP

Set a calendar reminder for exactly 30 days before your planned hike date and book the moment midnight HST passes. The 6:00 a.m. to 7:00 a.m. time slot sells out within hours of opening — sometimes within minutes — because it is the coolest part of the day and produces the best light for photos from the summit.
