10 Best Things to Do in Comoros

Looking for what to do in Comoros? Nestled in the turquoise waters of the Indian Ocean between Madagascar and Mozambique, the Comoros archipelago is one of the world’s last true hidden gems—a destination of raw, untouched beauty and profound cultural authenticity. Known as the “Perfume Islands” for its production of fragrant ylang-ylang and vanilla, Comoros is a place where volcanic peaks cloaked in rainforest meet pristine coral-fringed beaches, and where the rhythms of Swahili-Arab heritage pulse through ancient medinas. Offering an experience far removed from mass tourism, Comoros is for the intrepid traveler seeking peace, natural wonder, and a genuine connection with a rich island culture that has remained beautifully preserved.

From challenging ascents up active volcanoes and world-class marine encounters to wandering labyrinthine old towns, discovering aromatic plantations, and soaking in the serene pace of island life, here are the 10 best things to do in Comoros. This guide is designed to help you plan a perfect trip to a nation where adventure and tranquility exist side by side.

1. Conquer the Mighty Mount Karthala

Dominating the skyline of Grande Comore (Ngazidja), Mount Karthala is one of the world’s largest active volcanoes and the ultimate adventure for intrepid hikers. This colossal shield volcano features a vast caldera over 3km wide at its summit. The trek to the rim is a challenging multi-day expedition, typically starting from the village of Mvouni. The trail ascends through dense montane rainforest, home to unique birdlife, before emerging onto otherworldly lunar landscapes of ash and hardened lava fields.

Reaching the edge of the crater is a humbling and awe-inspiring experience, with panoramic views across the entire island and the deep blue of the Indian Ocean beyond. The hike requires a local guide, proper gear, and camping equipment, as it usually involves an overnight stay. For those who undertake it, climbing Karthala is not just a physical challenge but a spiritual journey into the powerful geologic heart of the archipelago.

2. Bask in Seclusion at Chomoni Beach

On the eastern coast of Grande Comore lies Chomoni Beach, a postcard-perfect slice of paradise that exemplifies the untouched beauty of Comoros. This crescent of brilliant white sand is lapped by calm, crystal-clear turquoise waters, all dramatically framed by imposing black volcanic rock formations. Unlike crowded tourist beaches elsewhere, Chomoni remains blissfully peaceful, often shared only with local fishermen and a handful of savvy travelers.

The beach is ideal for swimming in the sheltered lagoon, sunbathing on the soft sand, and snorkeling directly offshore, where vibrant coral gardens teem with tropical fish. The stark contrast between the white sand, black rocks, and blue water creates a photographer’s dream. A day at Chomoni is a day of pure, unadulterated relaxation and natural beauty.

3. Step Back in Time in Itsandra

Just north of the capital, Moroni, the historic coastal district of Itsandra is a living museum of Comorian heritage. This area was once the seat of powerful sultanates, and its legacy is etched into the landscape. Visitors can explore the imposing stone ruins of the Itsandra Fortress, wander among ancient royal tombs adorned with coral stone, and see the ruins of a historic mosque.

The seafront is particularly atmospheric, where traditional wooden fishing boats (ngalawa) are drawn up on the black sand beach against a backdrop of crashing waves. As the sun sets, the warm light bathes the old stones in gold, and locals gather to socialize and play football on the beach. Itsandra offers a poignant and tangible connection to the pre-colonial history of the islands.

4. Lose Yourself in the Medina of Moroni

The heart of the capital, Moroni, is its enchanting old medina, a labyrinth of narrow, winding alleyways that feel suspended in time. This is one of East Africa’s most authentic and well-preserved Islamic old towns. Whitewashed houses with intricately carved wooden doors and balconies crowd together, their windows overlooking bustling passages filled with the scent of spices and incense.

The focal point is the iconic Ancienne Mosquée du Vendredi (Old Friday Mosque), with its distinctive white minaret—a symbol of the city. Wandering without a map is the best approach, allowing you to stumble upon hidden courtyards, tiny tailor shops, Quranic schools, and vibrant fabric stalls. The medina is the cultural and spiritual core of Comorian life, offering an immersive glimpse into the daily rhythms and deep-rooted traditions of the people.

5. Dive into Biodiversity at Mohéli Marine Park

A UNESCO-listed biosphere reserve, Mohéli Marine Park is a conservation success story and a paradise for marine enthusiasts. Surrounding the island of Mohéli (Mwali), the park protects pristine coral reefs, seagrass meadows, and mangrove forests. It is one of the best places in the world to see green sea turtles, which nest on its secluded beaches and can be easily spotted while snorkeling.

The park is also a haven for humpback whales (July-October), dolphins, manta rays, and a dazzling array of reef fish. Visitors can join guided snorkeling or diving trips, take boat excursions to uninhabited islets like Île de Sable, or participate in turtle monitoring programs. The park’s existence ensures that Mohéli remains the wildest and most ecologically pristine of the three main islands.

6. Gaze Upon the Otherworldly Lac Salé

On the northern tip of Grande Comore, the landscape gives way to the surreal spectacle of Lac Salé (Salt Lake). This striking body of water sits within a deep, collapsed volcanic crater. Its waters are saline and, depending on the light and algae, shift in color from deep emerald green to milky turquoise, creating a dramatic contrast with the jet-black and rust-colored volcanic rocks that encircle it.

A short walk from the main road leads to viewpoints that overlook this serene and mysterious lake. There are no facilities here, just the powerful silence and beauty of a raw geological phenomenon. It’s a perfect spot for contemplation and photography, offering a starkly different landscape from the island’s lush interior and sandy coasts.

7. Discover Island Serenity in Nioumachoua

The tranquil fishing village of Nioumachoua, on the southern coast of Mohéli, is the gateway to some of the archipelago’s most idyllic scenery. The village overlooks a breathtaking bay dotted with small, forested islets. This area is the epitome of tropical serenity, where life moves at the pace of the tides.

From here, you can hire a local boatman to explore the nearby islands, such as Île de N’Droundé, for pristine snorkeling and picnics on deserted beaches. The waters are calm and crystal clear. Nioumachoua is also a base for eco-lodges and conservation projects, making it ideal for travelers who want to immerse themselves in nature and support sustainable tourism.

8. Uncover Ancient Roots in Iconi

South of Moroni, the historic town of Iconi is one of the oldest settlements in Comoros, steeped in legend and history. It was once a rival capital to Itsandra and is famed for its dramatic clifftop location and well-preserved ruins. Explore the remnants of Sultanic palaces and fortifications, and visit the Iconi Mosque, one of the oldest in the archipelago.

The town is perched above a rugged coastline, and a walk to the cliff edge rewards you with sweeping views of the ocean and the iconic Iconi Lighthouse. It’s a place that feels heavy with history, where you can almost hear the echoes of ancient sultanate battles and trading voyages. The nearby black sand beach is a popular local swimming spot, adding a touch of daily life to the historical atmosphere.

9. Follow the Scent on a Ylang-Ylang Plantation Tour

The intoxicating fragrance of ylang-ylang flowers is the signature scent of Comoros, which produces a major portion of the world’s supply of this essential oil used in high-end perfumery. A visit to a traditional distillery is a sensory and cultural must-do. In the agricultural villages of Grande Comore or Anjouan, you can tour small-scale plantations where the star-shaped yellow flowers are hand-picked at dawn.

You’ll witness the age-old distillation process, where the flowers are steamed in rustic stills to extract the precious oil. The air in these villages is perpetually perfumed, creating an unforgettable olfactory memory. This experience connects you directly to one of the islands’ most important economic and cultural traditions, far from the industrial production seen elsewhere.

10. Feast on Flavors and Immerse in Local Life

To truly know Comoros, you must engage with its cuisine and communal culture. Comorian food is a delicious fusion of Swahili, Arabic, French, and Malagasy influences. Sit down to a feast of pilao (spiced rice with meat), langouste à la vanille (lobster in vanilla sauce), mataba (cassava leaves cooked in coconut milk), and fresh grilled fish.

Visit the bustling Volo-Volo market in Moroni or the market in Fomboni (Mohéli) to see pyramids of spices, tropical fruits, and vibrant fabrics. The heart of Comoros, however, is found in its people and traditions. If you have the chance, witness a “grand mariage” celebration or local performances of “twarab” music and “msondo” dance. This immersion into the warm, generous, and proud island culture will be the most enduring memory of your journey.

In conclusion, Comoros is a destination for the soulful traveler. It offers not just sights, but profound experiences: the accomplishment of a volcanic summit, the serenity of an empty beach, the wonder of swimming with turtles, and the warmth of a culture that welcomes visitors as honored guests. These ten experiences are your invitation to discover one of the Indian Ocean’s best-kept and most authentic secrets.
