Why visit Comoros.
Comoros is for travelers who want an Indian Ocean island experience without resorts, cruise ships, or other tourists. There is no Maldives-style overwater bungalow scene; there are no five-star international chains. What there is, instead, is some of the most intact reef and marine megafauna in the western Indian Ocean, a culture that braids Swahili, Arab, French, and Bantu threads into something genuinely unique, and the cheapest way on earth to climb a 2,300m active volcano in two days.
Mount Karthala is the headline. The shield volcano dominates Grande Comore, and the standard climb takes two days from Moroni, a steep first day through forest and lava fields to a basic shelter near the rim, a pre-dawn second-day push to the summit caldera, and a long descent. The crater is huge (3 x 4 km) and active; the last significant eruption was in 2007, with smaller activity since. Local guides are essential; expect to pay €80–150 per person all-in for a basic 2-day climb.
Mohéli Marine Park is the other essential. Designated as the country's first national park in 2001 and recognised as a UNESCO Biosphere Reserve in 2025, it shelters green and hawksbill turtles (year-round nesting, peak August–October), humpback whale calving grounds (July–October), resident dolphin pods, and one of the western Indian Ocean's last viable dugong populations. Infrastructure is basic, small eco-lodges, sometimes village home-stays, but the wildlife is world-class.
Moroni rewards a couple of unhurried days: the Old Friday Mosque on the harbour, the Volo Volo market, and short trips to ylang-ylang distilleries inland. Anjouan offers spice and perfume plantations, terraced green hillsides, and Mt Ntringui hiking. Throughout, the anda Grand Marriage tradition shapes Comorian social life: men must throw a lavish, multi-week wedding (often costing $30,000+) to gain elder status and the right to wear the white bouti sash, a cultural anchor without obvious parallel elsewhere in Africa.
