The brief
Spice-island beaches and Stone Town’s carved doors: the Indian Ocean without the resort bubble.
Zanzibar runs on two dry seasons: June–September (the big one) and the short December–February window. The long rains (roughly March–May) are the deep low season, when many lodges discount hard or close.
