Heiau are temples or places of worship in pre-contact Hawaii, serving as architectural and ceremonial centers for chiefs’ consecration, harvest blessings, war declarations and endings, healing, and navigation star reading.
Most visitors to Hawaii gravitate toward beaches and waterfalls, but the islands hold something quieter and older. Scattered across every shoreline and valley are the stone platforms and enclosure walls of heiau — Hawaiian temples that anchored community life long before the first Western ship arrived. Some sit right next to busy roads; others require a hike through thick forest. All of them ask for respect, not just because of the laws that protect them, but because they still carry spiritual weight for many Hawaiian families today.
Can you visit ancient Hawaiian temples? Yes, but with clear rules: stay off the stone platforms, never move or add stones, and keep your voice low. Each site has different access — some are inside national parks with ranger-led programs, while others sit on private land and are closed to the public. Do your homework before you go, and treat every site like an active place of worship, not a photo backdrop. That approach made our visits feel meaningful rather than intrusive.

This article covers the different types of heiau, two of the most significant luakini temples on the Big Island, and the etiquette that keeps these sites protected for future generations. Whether you are planning your first culture-focused trip or adding one stop to a beach itinerary, understanding these rules matters more than ticking off a list.
Heiau: The Spiritual and Political Heart of Old Hawaii
Before Western contact, every Hawaiian island was divided into ahupuaʻa — land divisions running from the mountains to the sea. Each ahupuaʻa typically had at least one heiau, making them as common in the landscape as churches in a European town. Heiau were not uniform: their size, shape, and purpose varied. The largest were luakini, state-level temples where high chiefs conducted rituals that could include human sacrifice during times of war or political transition. Others were māpele or hoʻoulu ʻai, focused on agriculture and rain, while hoʻola heiau were dedicated to healing and koʻa served as fishing shrines.
What all heiau share is that they were built entirely by hand using lava rock — no mortar, no metal tools, just skilled labor moving stones that often weighed hundreds of pounds. The engineering is remarkable even by modern standards. Some platforms rise twelve feet high and span more than an acre. Standing in front of one, you get a sense of the collective effort it took to shape the land into something sacred. If you are interested in how cultural sites like these fit into a larger island history, a look at Molokai’s lesser-known cultural sites offers a quieter, less-visited counterpart to the Big Island temples.
Two of the most important luakini heiau survive on the Big Island, and both are open to visitors who follow the etiquette.
Puʻukoholā Heiau — The Temple on the Hill
Puʻukoholā Heiau sits on a hill overlooking the coast at Kawaihae on the Big Island. Built in 1790–1791 by Kamehameha I, it was a luakini heiau dedicated to the war god Kūkāʻilimoku. Kamehameha built it after a prophecy that constructing the temple would help him conquer all the islands — a prediction that came true when he unified Hawaii in 1810. The name translates to “hill of the whale,” and from the site you can see the Pacific stretching to the horizon.
The National Park Service manages the site, which means restrooms, water, and interpretive signs are available. A short paved path leads to a viewing area with a clear angle on the platform. Because the site is within the National Park System, drones are prohibited without a special permit — a rule the rangers take seriously. For those planning a day that combines history with scenery, the nearby Kawaihae harbor and the trails of Kauai’s Na Pali Coast share a similar sense of raw coastal power, though the landscape could not be more different.
Mookini Heiau — One of the Oldest Temples in Hawaii
A short drive north of Puʻukoholā, at the tip of the Kohala peninsula, lies Mookini Heiau. This luakini heiau is believed to have been built around 480 AD, making it one of the oldest surviving structures in the Hawaiian Islands. It was dedicated to the war god Kū and later became closely associated with Kamehameha I, who was born nearby. The walls rise about six feet high and enclose a large platform — the scale is impressive, especially considering the age.
Unlike Puʻukoholā, Mookini receives few visitors, which adds to its solemn atmosphere. The wind coming off the Pacific is constant, and the only sounds are waves and birds. The isolation means you are largely self-guided, so reading up on the site’s history before arrival makes a difference. The access road is rough — if you have rental car restrictions on unpaved roads, call ahead to confirm current conditions. For travelers mapping out a broader Big Island route, the volcanic formations along the island’s coastline pair naturally with a day that already heads north.
Knowing what to do and what not to do at a heiau is just as important as knowing which sites to choose.
How to Visit a Heiau Respectfully
The etiquette for visiting a heiau is not complicated, but it is non-negotiable. Hawaiian law — specifically Hawaiʻi Revised Statutes Chapter 6E — makes it a crime to take, alter, damage, or destroy historic property on state or private land without permits. Federal laws including the National Historic Preservation Act of 1966, the Archaeological Resources Protection Act of 1979, and the Native American Graves Protection and Repatriation Act of 1990 add layers of protection for sites on federal land. What that means for you, the visitor, is simple: look with your eyes, not your hands. The following sequence covers the typical flow of a respectful visit.
Find out whether the heiau is on public or private land, what hours it is accessible, and whether a permit or reservation is needed. Some sites, like Puʻukoholā, have a visitor center with posted hours. Others, like Mookini, have no facilities and limited signage. A quick check of the National Park Service or Hawaii State Parks website saves you a wasted drive.
Heiau are not playgrounds or photo studios. Walk to the designated viewing area and stay on marked paths or paved areas. Never step onto the stone platform or enclosed area — those spaces are considered the most sacred part of the temple. Maintain a low voice and turn off phone speakers.
You are welcome to take photos, but do so without stepping over barriers or roped-off areas. Do not use a drone — drones are banned in National Park System units, and state parks require permits that are rarely granted for casual use. If you want aerial footage of the landscape, a compact option under 249g like the DJI Mini 4K is light enough to skip FAA registration, but you still need landowner or park permission to launch near a heiau.
Do not leave coins, flowers, food, or any object at a heiau unless a caretaker explicitly invites you to. Mainland-style offerings are generally unwelcome and can attract pests. Do not stack rocks into cairns — it disturbs the archaeological context and is seen as intrusive by cultural practitioners. The rule is simple: take only photos, leave only footprints.

If you want to capture the scale of a heiau without a drone, arrive in the late afternoon when the sun is low. The long shadows emphasize the depth of the stone terraces and make the platform geometry visible from ground level. A polarizing filter on your phone or camera cuts the glare off the lava rock.
Practical Tips for Visiting Ancient Hawaiian Temples
Planning a respectful heiau visit starts with practical decisions about timing, gear, and transportation. The following considerations apply whether you are visiting Puʻukoholā, Mookini, or any other heiau across the islands.
Timing and Weather
Morning visits (before 10 a.m.) offer cooler temperatures and better light for photography. Heiau sites have little to no shade — the stone absorbs heat quickly, and by midday the exposure can be uncomfortable, especially for children. Afternoon rain is common on the windward sides of the islands, so check the forecast for the specific district. If you are short on time, prioritize Puʻukoholā over Mookini because of the visitor center amenities and clearer signage.
What to Bring
Water, sunscreen, a hat, and closed-toe shoes with good grip cover the basics. Many heiau involve walking on uneven lava rock or gravel paths. A leather daypack with a dedicated laptop compartment works well for carrying camera gear, water, and a field guide without feeling bulky — I used one on our Big Island trip and appreciated the luggage pass-through at the airport on travel days. Leave tripods at home unless you have confirmed the site allows them; some parks restrict them on sensitive terrain.
Access and Transportation
Puʻukoholā has paved parking and is accessible by standard sedan. Mookini requires a dirt road that turns slick after rain — rental car agreements often prohibit unpaved driving, so read the fine print or choose a vehicle with higher clearance. Neither site charges an entry fee, but Puʻukoholā accepts donations. If you are still weighing which side of the Big Island to sleep on, this interactive map of the island’s hotels and rentals makes it easier to compare proximity to the heiau sites against the beach or the trailhead.
Rock stacking is a growing problem at cultural sites across Hawaii. Visitors who build cairns at heiau or along nearby trails disturb archaeological layers and mislead other visitors into thinking the piles are part of the original structure. Under HRS 6E, moving stones from a heiau is theft of cultural property. If you see fresh cairns, leave them in place — do not knock them over, as that also disturbs the site. Report significant damage to the nearest park office.
- Heiau are protected by overlapping state and federal laws — treat every stone as irreplaceable.
- Visit early in the morning for better light, less heat, and fewer crowds.
- Never leave offerings or stack rocks; photograph from the perimeter only.
- Choose Puʻukoholā for an accessible, ranger-guided experience and Mookini for solitude and older history — but skip Mookini if your rental car can’t handle unpaved roads.
Before You Go: Big Island Heiau Questions Answered
Do I need a reservation to visit Puʻukoholā Heiau?
No reservation is required. The site is open daily during daylight hours, and the visitor center operates on a standard schedule. School groups and tour vans arrive around 10 a.m., so early morning offers the quietest experience.
Can I take my kids to a heiau, or is it too solemn?
Kids are welcome, as long as they understand the rules before entering. Keep the visit short — 20 to 30 minutes is enough to absorb the site without restlessness. Our kids did best at Puʻukoholā because the ranger talk held their attention.
What happens if I accidentally step on the platform?
At Puʻukoholā, a ranger will likely ask you to step back and explain why the area is off limits. The goal is education, not punishment, but repeat or deliberate violations can result in fines under state historic-preservation law. The perimeter is clearly marked, so accidental entry is rare.
Is there a downside to visiting Mookini Heiau?
The access road is the main drawback. After heavy rain, it becomes deeply rutted and sometimes impassable without four-wheel drive. There are no restrooms or drinking water, so you need to come prepared. If you have limited time or a low-clearance rental, Puʻukoholā is a more reliable choice.
Are there heiau on other islands worth visiting?
Yes. Every major island has significant heiau — from the restored platform at the National Park of American Samoa (culturally related but outside Hawaii) to sites on Maui and Oahu that are less visited than the Big Island examples.
