Zanzibar

Sultans' palaces, spice markets and alleys that end at the sea.

The north tip has the swimmable all-day water and the dhow builders.

Lunch on a boulder in the ocean — walk at low tide, boat at high.

Clove, vanilla, cardamom — taste the island's whole history in one garden.

Triangle sails against an orange sky — the Swahili coast's daily finale.
