One of Hawaii’s most popular tourist attractions is now requiring that out-of-state visitors make a reservation for entry.

A hike up Diamond Head State Monument (or Lē‘ahi as it’s known to locals) is essential when visiting O’ahu. Overlooking the surfer-dotted waters of Waikiki beach, the saucer-shaped crater is one of Hawaii’s most recognizable landmarks.

It is one of the state’s most popular attractions, receiving nearly 800,000 visitors per year according to government reports, with daily visitors typically exceeding 3,000.

Due to these high visitor numbers, the area requires a congestion-management plan to enhance the quality of experiences and minimize the impact on surrounding communities and resources. Consequently, starting April 28, visitors from out-of-state must make a reservation to enter Diamond Head as the new system goes live.

“The new reservation system is intended to reduce hiker and vehicle congestion,” stated Hawaii’s Governor David Ige, emphasizing that residents wanting to visit the state monument will not be impacted.

How to Reserve Entry to Diamond Head State Monument

Reservations must be made 14 days ahead of your visit. People without a valid Hawaii driver’s license or ID will need to secure a reservation to enter the park. Additionally, commercial tour and trolley patrons are also required to make a reservation.

While Hawaii residents will continue to enjoy free access without reservations, entry might depend on the availability of parking spaces on any given day.

Why is the Booking System Being Implemented?

The new reservation system is part of O’ahu’s Destination Management Action Plan (DMAP), which advocates for creating reservation systems for natural and cultural sites across the island. This plan aims to monitor and manage visitor flow, ultimately enhancing the experience for everyone.

By implementing the booking system at Diamond Head, it is expected to improve visitor safety, helping to minimize long lines at entry and crowding along the trails. Moreover, by regulating visitor numbers, park officials can better protect Diamond Head’s natural resources.

“The new reservation system will enhance the experience for all enjoyers of the monument, ensuring its preservation for future generations,” the tourism board expressed in a press release.

What Other State Parks Require Reservations in Hawaii?

This is the third state park in Hawaii to require reservations. Reservations are also mandatory at Hā‘ena State Park in Kaua‘i and Waiʻānapanapa State Park in Maui. Additionally, while not classified as a state park, reservations are required at Hanauma Bay Nature Preserve in O’ahu.
