Savour Arabian architecture, spices and aquarium-worthy reefs marooned off Africa’s east coast. Dip into UNESCO Stone Town for warren-like streets housing ruins, museums and dining atop the sultan’s private mosque. Surrender to wellness with meditation, meander through spices and dhow history, soak up rich flora and fauna, crater climb and wade through still, warm seas. Unwind on achingly exclusive Mnemba Island for barefoot luxury, or trek the rare Red Colobus monkey in one of its last remaining sanctuaries in the world. Dazzling and ecology devoted Zanzibar delivers far beyond laid back charm.
