Former palaces and Arab mansions along the twisting streets of Stone Town hint at a grander age for this port city on the western coast of Zanzibar. The Old Fort, built in the 1700s to fend off the Portuguese, now hosts local performances, a café and an art gallery. Overstuffed bazaars lend an air of nonstop bustle. Mafia Island Marine Park sits just offshore, a haven for snorkeling the local reefs. Day tours visit working plantations where the island's legendary spices are grown.
