Officially called the Union of the Comoros, this Indian Ocean archipelago is made up of three main islands: Grande Comore (Ngazidja), Mohéli (Mwali), and Anjouan (Nzwani). Each offers its own mix of lush tropical landscapes, historic Islamic cities, and vibrant markets. Once a favored port for sultans and pirates, the islands’ rich history is one of its major draws. Known as the "Perfume Isles" for the centuries-old spice plantations, visitors can also immerse themselves in fragrant spice tours or even try their hand at perfume-making—two unforgettable things to do in this storied destination.
