Most people picture Bora Bora as a place you view from a lounge chair, not a place you earn by climbing. But the island’s interior holds a network of trails that cut through dense jungle, past WWII relics, and up ridgelines with views that make the overwater bungalows look like toys from above. Roughly 32 kilometers of trail loop the island’s core, yet the vast majority of visitors never leave the coastal ring road.
This guide covers the hikes worth your time, what each one demands, and how to prepare for terrain that’s unmarked, muddy, and often completely empty of other people. It’s written for active travelers who want to see the volcanic spine of Bora Bora rather than just its lagoon — families included, with the right trail choices.
Bora Bora’s interior trails see a fraction of the visitors its lagoon does — roughly 32 km of loop trail exists, yet most tourists never set foot on it.
Yes, you can hike in Bora Bora — but it’s not a place for casual strolls. Trails are unmarked, often muddy, and cross private land. Stick to the well-trodden WWII Cannons trail for a short, rewarding walk, or hire a guide for anything deeper. The payoff is silence and views you won’t get from a boat.

| Trail | Best For | Standout Feature | Time Needed | Key Tip |
|---|---|---|---|---|
| WWII Cannons Trail | Short, easy hike with history | WWII-era gun emplacements above the lagoon | 30–45 minutes | Take the middle fork at the three-way junction about 0.5 miles in |

| Arete de Matira | Quiet ridge walk above the beach | Minimal crowds, ridge-top perspective of Matira Beach | 1–1.5 hours | Best at first light before the heat builds |
WWII Cannons Trail: History in a Short Walk
The easiest and most accessible hike on the island, the Chemin des Cannons trail starts near the Bora Bora Activity Center and climbs a steep gravel path through volcanic rock and switchbacks. It’s free, requires no guide, and takes about 30 to 45 minutes round trip. The reward is a set of WWII-era cannons positioned to defend the lagoon entrance — a tangible piece of military history that most visitors miss entirely.
The trail is straightforward, but the gravel can be loose, and the sun is relentless. Bring water and sun protection even for this short walk. At the three-way junction roughly 0.5 miles in, take the middle fork to reach the main gun emplacement.
Start the WWII Cannons trail by 7:30 a.m. — the sun is already strong by 9 a.m., and the gravel path offers no shade.
Mount Mata Pupu: Ridge Views With Real Risk
The trailhead for Mount Mata Pupu sits roadside near Pofai Bay, starting as a steep gravel road that doubles as a cell tower service road. It climbs steadily into a ridge hike with sections of volcanic rock scramble and a narrow, muddy ridgeline. An east-facing overlook side trail branches off for panoramic views of the lagoon and the surrounding peaks.
This is a moderate to challenging hike, and the wet volcanic rock can be dangerously slick. Check the weather before you go and skip it entirely after rain. The trail is unmarked, so downloading offline maps from AllTrails or Maps.me before you arrive is essential — cell service drops quickly once you leave the road.
Wet volcanic rock on Mount Mata Pupu turns the trail into a slip hazard. If it rained in the last 24 hours, choose a different hike.
Valley of the Kings: Culture and a Banyan Tree
The Valley of the Kings trail passes ancient marae (ceremonial stone platforms) and a massive banyan tree that some locals say inspired the floating mountains in Avatar. It’s a cultural and scenic walk that combines history with the island’s dense interior landscape. The trail itself is moderate, but the real value comes from understanding what you’re looking at — a licensed guide makes a significant difference here.
Government signs at the base of Mount Pahia and Mount Otemanu advise using a qualified tour guide, a recommendation that’s been in place since 2008. For the Valley of the Kings, a guide adds context to the marae and the tree that you won’t get from a map. Plan for 2 to 3 hours and carry at least 2 liters of water per person.
Arete de Matira: Quiet Ridge Above the Beach
Matira Beach draws crowds for its soft sand and calm water, but the ridge trail above it — Arete de Matira — sees almost no one. It’s a less-traveled path that offers ridge-top views above the beach and the lagoon beyond. The trail is short, around 1 to 1.5 hours, and the solitude is the main draw.
The trailhead can be hard to spot — look for a narrow path cutting inland just past the southern end of the beach. It’s unmarked, so having an offline map is helpful. Start at first light to beat the heat and the midday cloud cover that often rolls in by late morning.
Arete de Matira’s trailhead is easy to miss — look for a narrow path cutting inland just past the southern end of Matira Beach, before the road curves.
What to Know Before You Hit the Trails
Bora Bora’s hiking trails are not maintained like national park paths. They’re unmarked, cross private land, and conditions change with the weather. Preparation is not optional.
Navigation and Maps
Cell service drops quickly once you leave the coastal road. Download offline maps from AllTrails, Strava, or Maps.me before you arrive — specifically the French Polynesia map pack. Carry a power bank if you’re using your phone for navigation, and consider a backup paper map or screenshot of the route.
What to Bring
Carry 2 to 3 liters of water per person, even for shorter hikes. Sturdy footwear with good grip is essential — trail runners or light hiking boots work, but flip-flops and sandals are dangerous on wet volcanic rock. Sun protection (hat, sunscreen, sunglasses) and insect repellent are non-negotiable. A headlamp is smart if you’re starting at first light or think you might be out longer than planned.
| Item | Why It Matters | Our Pick |
|---|---|---|
| Water | 2–3 liters per person; heat and humidity spike by mid-morning | Reusable bottles or a hydration bladder |
| Footwear | Wet volcanic rock is slick; loose gravel on switchbacks | Trail runners or light hiking boots with deep lugs |
| Navigation | Trails are unmarked and cross private land | Offline maps (AllTrails, Maps.me) + power bank |
| Sun & Bug Protection | No shade on most trails; mosquitoes in the interior | SPF 50+ hat, long sleeves, DEET-based repellent |
Guides and Safety
Licensed guides are recommended for interior trails, especially Mount Pahia and the Valley of the Kings. Three trusted guides operate on the island, and a government sign at the base of Mount Pahia and Mount Otemanu has advised using a qualified tour guide since 2008. Rope-assisted scrambles exist on some routes, and a guide will have the proper gear and knowledge of current conditions.
Check the weather before you head out. Avoid trails after heavy rain — mud and slick roots make even moderate hikes dangerous. Start at first light to avoid the heat and the midday cloud cover that can obscure views.
Mount Otemanu’s summit is a technical basalt plug and is off-limits to climbers. You can walk the saddle and lower slopes for close-up views, but don’t attempt the peak itself.
- Stick to the WWII Cannons trail for a short, safe hike — it’s the only one that’s clearly marked and doesn’t require a guide.
- For anything deeper, hire a licensed guide. The terrain is unmarked, crosses private land, and conditions change fast.
- Start every hike at first light. Heat, humidity, and cloud cover make midday hiking miserable and dangerous.
Before You Go: Bora Bora Hiking Questions Answered
Do I need a guide for every hike?
No. The WWII Cannons trail is short, easy, and free — no guide needed. For Mount Mata Pupu, the Valley of the Kings, or any interior route, a licensed guide is strongly recommended. Government signs at the base of Mount Pahia and Mount Otemanu have advised using a guide since 2008.
Are the trails safe for kids?
The WWII Cannons trail is fine for kids who can handle a steep gravel path for 30 minutes. Mount Mata Pupu and the Valley of the Kings are better suited to older kids (12+) with hiking experience. Wet volcanic rock and narrow ridgelines are real risks for younger children.
What’s the biggest mistake people make?
Underestimating the heat and the terrain. Most people show up in flip-flops with a single bottle of water. Trails are unmarked, and cell service drops quickly. Download offline maps, carry 2–3 liters of water per person, and wear proper footwear.
Is Mount Otemanu climbable?
No. The summit is a technical basalt plug and is off-limits. You can walk the saddle and lower slopes for close-up views of the peak and the lagoon, but don’t attempt the summit itself. Stick to the approved trails.
What’s the best time of year for hiking?
Dry season (May to October) offers the most stable conditions. Trails are less muddy, and the risk of afternoon rain is lower. Even then, start at first light — the heat and humidity rise sharply by mid-morning, and cloud cover often rolls in by late morning.
Why the Interior Rewards the People Who Show Up Prepared
Bora Bora’s hiking trails aren’t a side attraction — they’re a completely different version of the island. The lagoon is beautiful, but it’s also crowded. The interior is quiet, raw, and demands something from you. If you show up with the right gear, a downloaded map, and a willingness to get muddy, you’ll see a side of Bora Bora that most people fly home without knowing exists. For a broader look at what the island offers beyond the water, the guide to Bora Bora’s mountain viewpoints covers the best places to take in the landscape without breaking a sweat.
