Travel to Babylon, the ancient capital of southern Mesopotamia, and trace the footsteps of Alexander the Great. Tour Saddam Hussein's rebuilt Babylon with its vibrant aqua-blue Ishtar Gate (a reproduction of the original) and compare it to one of his once-opulent palaces just behind the complex. Continue on to Karbala, a holy city for the Iraqi Shia, holding the shrine of the martyred Imam Husayn Ibn Ali (died 680). Return for dinner at your hotel.

Today travel to the holy city of Najaf, and along the way stop in the town of Al Kifl to marvel at its 7th-century Kufa Mosque, the holiest place for Shia Muslims. Then continue on to Najaf and after settling in the hotel, discover the shrine of Imam Ali. This masterpiece of Islamic architecture holds the tomb of Imam Ali, the fourth caliph who was the cousin and later son-in-law of the Prophet Muhammad. In the evening, soak up the buzz of the nearby souk and savor dinner at the hotel.

Head to Samawa, a city on the banks of the Euphrates River that holds the archeological site of Warka, also known as Uruk. Explore the magnificent remains of this ancient Sumerian city that thrived around 2900 B.C. and was supposedly the first city on earth. Continue to the busy hub of Nasiriya, one of Iraq's largest cities and the capital of the Dhi-Qar province. In the evening, feel the city's pulse on a stroll through its bustling souk, then enjoy a local dinner.

Tour the UNESCO World Heritage Site of Ur, an ancient Sumer city believed to be the birthplace of Prophet Abraham. Climb up the steep stairs to the Ziggurat of Ur, a splendid temple dedicated to the lunar god Nanna and built the same way as the biblical Tower of Babel. After lunch, head to Nasiriya's lively bazaar for a dash of local buzz and a quest for souvenirs, from mabhara incense lamps to artisanal copperware and traditional sweets.

Spend the day on the Tigris River, venturing into its dreamy marshes by boat. Navigate between islands of reeds and lakeside villages inhabited by Marsh Arabs, and take in the resplendent beauty of this unique aquatic environment inside a desert. En route to the town of Basra, stop to soak up the beauty of the Paradise of Aden (Garden of Eden) where Tigris and Euphrates rivers meet.

Wander around the old city of Basra, once known as the Venice of the East for the Ottoman Shenashil Houses, traditional 19th-century residences that line its canal. Think back to the city's glory days as you explore one of the villas that was owned by a wealthy Greek merchant — a rare showcase of a bygone era. Wrap up the journey with a boat ride on Shatt Al-Arab, the river created by the Tigris and Euphrates merging, and soak up one last splendid Iraq sunset. Enjoy a farewell dinner tonight.

After breakfast, transfer to Basra International Airport for your homeward-bound flights and bid farewell to Iraq.
