At Marae Fare Opu, a sacred Polynesian ceremonial platform on Bora Bora’s main island, the road literally cuts through the archaeology. On one side, a few standing coral slabs. On the other, more rubble and infill. And scattered across both sections, carved into the ancient coral, are petroglyphs — most notably, turtles. Visitors who stop here often remark on the contradiction. Gerry Schaefer, who visited and left a review, put it plainly: “The road cut through the Marae and all that you can easily see is a small section formed of vertical coral slabs with infill. The turtle petroglyphs are nice.” That tension — between a site of deep spiritual and historical significance and its current state as a roadside relic — is the starting point for understanding Bora Bora’s petroglyphs. What do these carvings actually tell us about the society that made them? And how should a curious visitor engage with sites that are both sacred and neglected?

Petroglyphs in Bora Bora are not museum pieces behind glass. They remain in situ on marae — open-air ceremonial platforms that were the religious and political centers of pre-contact Polynesian society. The carvings are vulnerable, the sites are under-resourced, and the experience of seeing them requires more effort and less expectation than a typical tourist attraction. But that is also what makes them valuable: they offer a direct, unmediated encounter with a culture that left no written records, only stone.
Bora Bora’s petroglyphs are worth seeking out, but not for the reasons most people visit the island. They are not grand, well-signed, or easy to interpret. They are small, weathered, and often overlooked. What they offer instead is a raw connection to pre-contact Polynesian religion and social structure — if you come prepared to look carefully and bring your own context. The two main site types, Marae Fare Opu and the interior valley marae, offer very different experiences, and knowing the difference matters.
Two main locations concentrate Bora Bora’s known petroglyphs. They differ dramatically in setting, preservation, and access.
| Site | Location | Period of Use | Key Petroglyphs | Access | Signage & Interpretation |
|---|---|---|---|---|---|
| Marae Fare Opu | Coastal, main island, bisected by road | Pre-contact, exact period undated | Turtle carvings, coral slab infill patterns | Free, roadside parking, no gate | None — no explanatory boards |
| Valley Marae (interior) | Interior valley, ~3 km from coast | 14th–16th centuries (excavated 2010) | Upright basalt stones, platform carvings | Hiking trail, 4WD recommended, guide advised | None — site is overgrown |
The valley site was excavated in 2010 and has more precise dating. Fare Opu remains undated in the published record, which is itself a revealing detail about how unevenly archaeological resources are distributed across French Polynesia.
Petroglyphs and the Marae: Bora Bora’s Ceremonial Landscape
Petroglyphs in Bora Bora are almost never found in isolation. They belong to marae — rectangular or raised platforms built from coral slabs or basalt stones, used for rituals, royal investitures, and community gatherings. The word marae refers to both the physical structure and the sacred space it occupies. In Bora Bora, marae were the stage for interactions between the living, the ancestors, and the gods. Carving a symbol into the stone of a marae was not decorative. It was an act of consecration, marking the site as permanently under the protection of a particular deity or ancestral lineage.
Bora Bora’s petroglyphs are carved into two types of stone: coral limestone near the coast and basalt in the interior. The techniques differ accordingly. Coral is softer and allows for deeper, more rounded grooves. Basalt is harder and the carvings tend to be shallower, more linear. Both materials weather quickly in the tropical climate, which means many carvings are now faint and easily missed by an untrained eye. The island’s petroglyphs have never been comprehensively catalogued, and local knowledge of their locations is unevenly held.
Marae Fare Opu: The Roadside Sanctuary
Marae Fare Opu is the largest remaining marae on Bora Bora, though “largest” is relative. What remains is a fragment: a section of vertical coral slabs with infill, some paving stones, and the petroglyphs. The site’s location on the main road makes it easy to find, but that same road has damaged the integrity of the structure. Travelers who expect a curated archaeological park are often disappointed. Reviews consistently note the lack of explanatory boards, the small size, and the sense that the site is not well cared for. One visitor described it as looking like “a pile of rocks.”
Yet the petroglyphs themselves reward close attention. The turtle carvings are the most prominent. Turtles held deep significance across Polynesia: they were associated with long-distance navigation (sea turtles travel vast distances), with fertility, and with the god Ta’aroa in some traditions. The turtle motif appears repeatedly in Bora Bora’s petroglyph record, suggesting a specific ritual or chiefly association. What exactly that association was is still debated among archaeologists and oral historians. No surviving oral tradition explicitly explains the Fare Opu turtle carvings, which means any interpretation is partial.
At Marae Fare Opu, look for the turtle carvings on the coral slabs closest to the road. They are easiest to see in early morning or late afternoon light, when low sun angle creates shadow contrast. Bring a smartphone photo and zoom in — details invisible to the naked eye often show up on camera.
The Valley Marae: Deeper into the Interior
The interior valley marae of Bora Bora offer a different experience entirely. Located roughly three kilometers from the coast, these sites lie in dense jungle, reached by hiking trails that wind through mango, breadfruit, and noni trees. The 2010 excavation of one valley marae revealed a platform measuring 10 x 8 meters, with eight upright basalt stones, the tallest standing two meters high. This site was in use from the 14th to the 16th centuries, placing its construction in the period of intensive Polynesian settlement and social stratification across the Society Islands.
Visiting the valley marae requires more planning. The trail is not marked, a 4WD vehicle or guided tour is recommended, and the site itself is overgrown. Stepping on the structures is not allowed — these are still considered sacred by some local families — but viewing from the perimeter is possible. The effort yields a more intact site and a stronger sense of the original setting: a ceremonial space hidden in the interior, away from the lagoon and the villages.
What the Carvings Tell Us
Bora Bora’s petroglyphs are not narrative. They do not tell stories in the way a painted manuscript or a carved frieze does. Instead, they mark — they assert presence, claim lineage, invoke a deity. The turtle motif is the most documented, but other forms exist: geometric patterns, human figures (sometimes called tiki in broader Polynesian contexts), and abstract designs whose meanings are lost. The absence of any surviving oral tradition specifically tied to these carvings means that archaeologists work with comparative evidence from other islands, which carries its own risks of overgeneralization.
One of the likeliest misconceptions among visitors is that the carvings are “primitive” or “simple.” In fact, the effort required to carve coral or basalt with stone tools was enormous. The decision to carve a turtle into a marae was a significant investment of labor and ritual authority. The fact that so few petroglyphs survive on Bora Bora compared to, say, the Marquesas Islands (which have an extraordinarily rich petroglyph tradition) is likely due to a combination of factors: the softer coral stone weathers faster, the island’s marae were actively dismantled or neglected after Christianization in the 19th century, and modern development has covered or destroyed many sites.
A common mistake is to assume that Bora Bora’s petroglyphs are “just” art or decoration. In Polynesian societies, carving into a marae was a ritual act with religious and political meaning. Treating the site as a photo backdrop or stepping on the coral slabs disregards its ongoing sacred status for some local families. The lack of signage or maintenance does not mean the site is abandoned — it means the resources for interpretation have not been allocated, which is a different thing entirely.
Visiting Bora Bora’s Petroglyphs
If you want to see Bora Bora’s petroglyphs, the first decision is which site suits your interests and resources. Marae Fare Opu is the obvious choice for a brief stop: it is free, open-access, and takes fifteen to thirty minutes. The lack of signage means you should read up beforehand or bring a guide. Dress modestly — this is a former ceremonial site, and swimwear or beach cover-ups are not appropriate. The site is small, so combining it with other nearby attractions makes sense for a fuller day.
For the valley marae, a guided tour is strongly recommended. The trail is unmarked, the terrain is uneven, and the site is easy to miss even when you are standing next to it. A local guide can provide context that no signboard would. Several operators offer cultural tours that include interior valley visits alongside other stops. These tours typically use 4WD vehicles to reach the trailhead.
When visiting either site, bring water, sun protection, and insect repellent. The valley is hot and humid, and the coastal site has no shade. Do not touch or lean on the carved stones — oils from skin accelerate weathering, and the carvings are already fragile. Photography is allowed, but flash should be avoided to protect the stone’s surface patina.
For those who prefer a structured experience, consider booking a cultural tour that includes marae visits or a historical and heritage tour that covers the island’s archaeological sites. These can provide the context that the sites themselves lack.

Context and Comparison: Petroglyphs Across Polynesia
Bora Bora’s petroglyph tradition is part of a much wider Polynesian practice of rock carving, but it has distinct local features. Comparing the island’s carvings with those from better-studied archipelagos clarifies what is typical and what is specific to Bora Bora.
| Region | Primary Stone | Common Motifs | Typical Setting | State of Preservation |
|---|---|---|---|---|
| Bora Bora (Society Islands) | Coral limestone, basalt | Turtle, geometric designs, human figures | Marae platforms, coastal and interior | Variable; many sites degraded or lost |
| Marquesas Islands | Basalt, tuff | Human figures (tiki), lizards, discs, spirals | Rock faces, boulders, platform edges | Extensive; many well-preserved |
| Easter Island (Rapa Nui) | Volcanic tuff, basalt | Birdman (tangata manu), canoes, faces | Rock shelters, ceremonial platforms | Variable; some eroded, some restored |
| Hawaii | Lava rock | Human figures, dots, cupules, paddlers | Lava fields, temple sites (heiau) | Variable; urban development a major threat |
The Marquesas have by far the richest petroglyph tradition in Polynesia, with thousands of recorded carvings. Bora Bora’s record is much smaller, which may reflect genuine historical differences in carving practices, or simply the lack of sustained archaeological survey. The Society Islands as a whole have received less petroglyph research than the Marquesas or Hawaii. That research gap is itself a finding: it shapes what we can and cannot say about Bora Bora’s carvings.
The 2010 excavation of the valley marae on Bora Bora is one of the few archaeologically dated petroglyph-associated sites in the Society Islands. The 14th–16th century range aligns with a period of political centralization across the archipelago, when chiefly lineages were consolidating power through ritual and monumental construction.
- Bora Bora’s petroglyphs are not decorative art but ritual markings on sacred marae platforms, tied to Polynesian religion and chiefly authority.
- The two main site types — coastal Fare Opu and interior valley marae — offer very different access and preservation conditions; neither has on-site interpretation.
- Comparison with other Polynesian islands shows that Bora Bora’s petroglyph tradition is real but modest in scale, and under-researched relative to the Marquesas or Hawaii.
- Visiting these sites requires preparation, modest dress, and respect for their ongoing sacred status — the lack of infrastructure is not an invitation to treat them casually.
Questions Readers Ask
Where exactly are Bora Bora’s petroglyphs located?
The two main accessible sites are Marae Fare Opu (on the main coastal road) and an interior valley marae reachable by hiking trail about 3 km inland. Coordinates for the valley site are approximately -16.49140, -151.72890.
What do the turtle carvings mean?
The turtle is a recurring symbol across Polynesia, associated with navigation, fertility, and the god Ta’aroa in some traditions. The specific meaning at Fare Opu is not recorded in surviving oral histories, so interpretation relies on comparative evidence from other islands.
Do I need a guide to see the petroglyphs?
For Marae Fare Opu, no — it is roadside and free. For the valley marae, a guide is strongly recommended due to unmarked trails and overgrown terrain. Cultural tours that include marae visits are a practical option.
Are the petroglyphs well preserved?
Not consistently. Coral stone weathers quickly, and Fare Opu shows signs of wear from exposure, road construction, and lack of maintenance. The valley site is more intact but overgrown. Neither site has protective measures beyond their remote location.
Is there an entry fee?
No. Both sites are open-access and free. No tickets, no gates, no staff. This is part of why they lack signage and maintenance — there is no revenue stream supporting interpretation.
Beyond the Stone: What Petroglyphs Reveal About Island Society
Bora Bora’s petroglyphs are not the island’s main attraction, and they do not try to be. They are quiet, weathered, and easily missed. But they are also some of the only direct evidence of how pre-contact Polynesians marked their world with meaning. The fact that the carvings survive at all — despite roads, despite neglect, despite centuries of climate and change — is itself a kind of statement. They were made to last, and they have. What we make of them now depends on how carefully we look, how much context we bring, and whether we treat them as artifacts or as the still-sacred markers they were always meant to be.
