Choose the north (Nungwi, Kendwa) if you want to swim at any hour — it is the only coast barely affected by tides. Choose the east (Matemwe, Paje, Jambiani) for barefoot quiet, kitesurfing and lagoon reefs, and treat low tide as part of the rhythm rather than a flaw.
The tide question is the single most important thing brochures gloss over. On the east coast the ocean retreats several hundred metres twice a day. Locals plan around it; surprised honeymooners write disappointed reviews. We simply match you to the right coast first — then the right property.
One night, yes — almost always at the start, when you land. A dawn walk through the lanes before the heat, a spice farm en route north, dinner on a rooftop as the muezzin and the church bells overlap: that is Zanzibar’s soul, and it takes exactly one well-planned night. Two nights only if architecture and history are your reason for coming.
