Things to Do in Mangareva
& the Gambier Islands —
Top 7 Activities 2026

An exceptional, little-known lagoon

Around Mangareva stretches one of the most beautiful lagoons in French Polynesia. Less well-known than the Tuamotu atolls, the Gambier lagoon captivates with its deep blue gradients, deserted motus and peaceful, almost mystical atmosphere. Locals offer boat trips in traditional canoes or pirogues to reach the most spectacular motus: Taravai, Aukena and Akamaru.

On these islets, white sand beaches lined with coconut palms invite you to relax, swim and snorkel in crystal-clear water hosting tropical fish, giant clams and multicoloured corals. Motu Taravai, the largest and most inhabited, shelters a friendly village and the ruins of an old church. Further out, Aukena draws visitors with its immaculate beaches and ancient stone prison, while Akamaru reveals a charming coral church and exceptional panoramic views over the lagoon.

Mont Duff — 441m, 3.3 km, 2h return

Mont Duff is the unmissable hike on Mangareva. The island's highest point at 441 metres, it offers a 360° panoramic view over the entire lagoon, the motus of Taravai, Aukena, Akamaru and the coral reef encircling the archipelago. The trail starts near Rikitea and winds through lush tropical forest — wild hibiscus, tree ferns, guava trees.

Key facts: 3.3 km return, +350m elevation gain, about 2 hours return. Medium difficulty, accessible without a guide for those in good physical shape. Bring water, hiking shoes and set off early morning to avoid the heat.

Mont Mokoto — tranquillity and views over an endless ocean

Mont Mokoto, slightly lower but equally spectacular, appeals to hikers looking for peace and quiet. Less visited, its trail winds through wooded sections and open ridges, ideal for spotting endemic birds and tropical plants. At the summit, the silence and the view over the infinite ocean offer a suspended moment — the genuine feeling of being alone at the edge of the world.

The living heart of the Gambier Islands

The beating heart of the Gambier Islands, the village of Rikitea embodies the gentleness and authenticity of Polynesian life. Colourful houses, flowering gardens, peaceful atmosphere — this small port nestled between mountain and lagoon is far more than a stopover. Each morning, the local market slowly comes to life: sun-drenched tropical fruits, fresh fish caught in the lagoon, handicrafts, and sometimes raw pearls sold directly by pearl-farming families.

Craftwork plays an important role: women weave pandanus to make hats, mats and baskets, while others carve mother-of-pearl. These skills, passed down with pride, help preserve the cultural identity of the Gambier. Wandering through Rikitea's calm streets is to feel that intimate connection between people and nature.

A masterpiece in coral at the heart of the Pacific

Built between 1839 and 1841 by Catholic missionaries, Saint-Michel Cathedral is one of the most impressive monuments in all of French Polynesia. Constructed from locally quarried coral and basalt blocks, its imposing facade flanked by two symmetrical towers testifies to the ambition and craftsmanship of its builders. Inside, the mother-of-pearl choir is a unique artisanal masterpiece — shimmering in the natural light.

Saint-Michel Cathedral is not merely a place of worship: it's a symbol of faith and cultural mixing between Polynesian traditions and Western influence. Around the village, you'll also discover the ruins of the seminary, convent and former missionary schools.

The Gambier: birthplace of the Tahitian black pearl

The Gambier Islands are considered one of the birthplaces of the Tahitian black pearl — the first pearl farms were established here in the 1960s. Mangareva's lagoon, rich in nutrients and largely unpolluted, provides ideal conditions for pearls of exceptional quality: their iridescent reflections range from silver-grey to peacock green, sometimes tinged with blue or aubergine.

At Gambier Pearls, the pearl farm in Rikitea, you can visit and understand the full process: the delicate grafting, growth on culture lines, harvest and sorting by lustre, shape and colour. It's also the opportunity to buy pearls directly at the source — jewellery of rare quality, at prices far more interesting than in Papeete.

The first Catholic mission in Polynesia

The Gambier Islands are a genuine open-air museum of Polynesian religious heritage. In the 19th century, it was here in Mangareva that Catholic missionaries established the first mission in Polynesia, permanently transforming the local culture and landscape. The ruins are still visible everywhere: coral-stone churches, convents, old colleges, presbyteries and workshops.

Among the most striking sites: the ruins of the Saint-Raphaël seminary and the Rouru convent in Rikitea, sometimes swallowed by vegetation. On Akamaru, the Notre-Dame de la Paix church (opened in 1831) remains a jewel facing the lagoon. On Taravai, the Saint-Gabriel church impresses with its twin bell towers and mother-of-pearl décor.

A rare artisanal honey

Among the Gambier's natural riches, local honey holds a special place. Produced in small quantities by a handful of local families, it is considered one of the purest honeys in all of French Polynesia. The hives placed on the verdant heights of Mangareva benefit from a completely preserved environment, free from pollution and pesticides.

The bees forage on endemic and tropical flora — citrus flowers, hibiscus, uru (breadfruit tree), eucalyptus and coconut palms — giving the honey a delicate, floral, slightly vanilla taste. This rare product is often sold directly on site or at markets in Tahiti. A source of local pride, symbolising the balance between preserved nature and local craftsmanship.
