Begin your tour at the Hippodrome, where thousands of spectators once marveled at chariot games. Your day includes travels on foot and public transportation, so be sure to wear comfortable shoes. Travel from ancient to medieval eras with stops at the Serefiye Cistern and the Grand Bazaar, where you can take a Turkish coffee break and haggle for souvenirs in over 4,000 different shops.
Next, you’ll head to Istanbul University and an old book market, and then get a peek at Suleymaniye, considered the loveliest of the Ottoman-era mosques. After a stop at the cavernous Spice Market, veer off the tourist track in the city's Old Greek and Jewish neighborhoods, where you’ll see centuries-old wooden mansions. Finally, get views of Istanbul from the water with a scenic ferry ride across the river.
