You can find out about the history of Zanzibar Town with a trip to Darajani Market. Stroll along the seaside or visit the shops in the area.
If you're planning a bit of sightseeing head to Slave Market— just one of the monuments in Stone Town. Why not take a stroll along the beaches and watch the sunset while you're here? It's also full of great shops and restaurants, so you can spend the afternoon having a wander.
