Backpacking in Lac Salé
👌 Worth visitingattraction ranked #3
By Johan Kruseman 🇳🇱 | Updated October 22, 2026

Sulfur hangs in the air before the water comes into view, and the crater rim crunches underfoot as you step toward a lake the color of a cheap green bottle. Lac Salé sits on Grande Comore (Ngazidja) in the Comoros, on the southern slopes of Mount Karthala's neighborhood, a short ride from Moroni. The salt lake fills an old volcanic crater beside the sea at Maluzini, and it is small, so don’t expect a long hike. Crowds are rare; you may share the rim with a few local kids and goats. Costs stay low, though a driver or shared taxi is the real expense, and there are no facilities, so bring water and shade. Mid-day heat on the black rock is punishing. What you get is a strange, quiet, slightly eerie place where fresh seawater seeps through lava and the crater wall drops to a flat emerald surface, with the Indian Ocean surf booming just beyond the rocks.

Discover everything you want to know in the 📖 Comoros Travel Guide.

✨ Why go?
Ranked #3 attraction in ComorosWhat makes it a must-see attraction

Lac Salé is one of the few places in the Comoros where you can stand on the rim of a volcanic crater and watch a salt lake that fills it with water seeping in from the ocean, so you see volcanic geology rather than just reading about it. The crater sits at Maluzini, close to the coast, which means you can pair it with black lava shoreline in a single easy outing. Most travelers come to Grande Comore for Mount Karthala, and this lake is the low-effort companion: no permit, no guide required, no overnight gear. It also gets you into villages along the southern coast road, where fishing boats rest on the sand and you hear Shikomori rather than English. If you only have a day outside Moroni, the combination of the green lake, sea cliffs and quiet rural stops makes it worthwhile. Go for the oddness … read more 👉

Go for the oddness of the place and the near-total absence of other tourists.

💡 HighlightsTop highlights of Lac Salé

  1. The crater lake itself. A green, saline pool inside a volcanic bowl, with a slightly sulfurous smell and still water that mirrors the sky on calm mornings.
  2. The crater rim walk. A short loop on dark volcanic rock gives you views down into the lake and out to the sea, and it takes well under an hour.
  3. The seawater seepage. The lake is linked to the ocean through porous lava, and you can notice the water level shifting subtly with the tides.
  4. The black lava shoreline. Just beyond the crater, jagged basalt meets the surf, and waves thump into blowholes and crevices.
  5. Maluzini village life. Nearby, you see fishing canoes, drying nets and small mosques, a quiet glimpse of daily life on Ngazidja.
  6. Coastal road views. The drive south shows banana groves, breadfruit trees and views up toward Karthala’s slopes.

Most visitors stay on the rim and never walk down toward the ocean side, where the lava coast and its blowholes are more dramatic than the lake itself.

🌤️ When to go?When to go for the best experience

  • Dry Season (May to October): Lac Salé is best visited now. Days run 25 to 29°C (77 to 84°F), nights drop to about 20°C (68°F), and rain is rare, so the crater rim paths and the salt lake shore stay firm underfoot. Daylight lasts about 11.5 to 12 hours.
  • Hot, Wet Season (November to April): Expect 28 to 32°C (82 to 90°F), heavy humidity and downpours that turn trails slick. Cyclone risk peaks from January to March. The lake color looks flatter under cloud, and boats and ferries can be disrupted.
  • July to September: Diaspora families return to Grande Comore for weddings (grands mariages), so flights and rooms fill and prices climb. Local life around Mitsamiouli is livelier, though quiet viewpoints at the lake are still easy to find.
  • Ramadan: Daytime food options shrink and opening hours shift. Evenings

Book flights to Moroni for June or early October if you want dry weather without the peak summer fares.

🛏️ Where to stay?How to pick the right area

Mitsamiouli is the practical base for Lac Salé, the salt crater lake on the northern tip of Grande Comore, a few kilometers from the town. It has the island’s best-known white beach at Trou du Prophète, small guesthouses, and local restaurants serving grilled fish and cassava. Expect simple rooms, family-run places, and the chance to meet other travelers over dinner. Dress modestly in town, as this is a conservative Muslim community, and walk back before dark with a flashlight since street lighting is patchy.

Expect simple rooms, family-run places, and the chance to meet other travelers over dinner. Dress modestly in town, as this is a conservative Muslim community, and walk back before dark with a flashlight since street lighting is patchy.

Moroni, the capital, is the second option, roughly an hour or so by road to the south. It offers the widest choice of budget rooms, the Volo Volo market, ATMs, and the most contacts for shared taxis and guides. It suits you if you plan to explore Mount Karthala, Itsandra and other sites over several days, and want a social scene with other backpackers and expats. The trade-off is a daily commute to the north.

Smaller villages along the northern coast, such as Bangoi-Kouni, offer homestays arranged through local contacts, quiet nights and genuine village life. Ask in Mitsamiouli about family rooms rather than relying on online listings, since many places take bookings by phone or WhatsApp only.

FAQTraveler FAQ

Half a day is enough for Lac Salé, and 2 to 3 hours covers the lake shore and the crater views. Add the beach at Trou du Prophète in nearby Mitsamiouli and you fill a full day. Staying overnight in Mitsamiouli lets you visit early, when it is cooler.
Lac Salé is worth visiting because there is usually no formal entrance fee, only a small tip of about €0 to 2 for local help or parking. The crater lake is a quick, cheap add-on to a northern Grande Comore day. A local guide at around €5 to 10 gives context on the volcanic origins.
Reach Lac Salé from Moroni by shared taxi or private car to Mitsamiouli, about 45 to 75 minutes by road, then continue a few kilometers to the lake. Shared taxis cost roughly €2 to 4 each way. Flights land at Prince Said Ibrahim airport near Moroni, so most travelers go by road from there.
⚠️ Things can change over time, so always validate details locally before you go.

We 💚 feedbackKey takeaways before you go

Lac Salé looks small, and that is why people hurry. Linger instead on the seaward side, where the lava meets the surf and the blowholes hiss and spray, because that edge is far wilder than the crater. I would come in the cooler morning hours, wear sturdy shoes for the sharp rock, and bring more water than seems sensible.
