See the National Museum of Zanzibar (rebuilt in 1883) and the Arab fort while passing along bazaar streets towards the famous Freddie Mercury house. See the old slave market, fruit market, and spice market — don’t miss the classic Zanzibar curved doors decorating the stone town. 

After you have explored Stone Town, you’ll have an opportunity to take a short break and have lunch before heading to Prison Island. Prison Island is also known as Changuu Island, the nickname came from the island being used by some sultans of Zanzibar to detain enslaved people. While you are on this island, you can swim, snorkel and take pictures with giant tortoises. 

See the colorful schools of black snappers, orange lined triggerfish, spotted garfish, barracudas, longfin bannerfish, emperor angelfish, rabbitfish, clown triggerfish, and many more.
