Fascinating Vietnam, Cambodia & the Mekong River with Hanoi & Ha Long Bay (Southbound)

Cairo, where five thousand years of civilization press upon the present with relentless intensity, is anchored by the Great Pyramid of Giza — the sole survivor of the Seven Wonders of the Ancient World, already ancient when Cleopatra walked in its shadow. The Egyptian Museum's overwhelming treasure trove of pharaonic antiquities, including the golden mask of Tutankhamun, and the medieval labyrinth of Islamic Cairo, a UNESCO-listed district of a thousand mosques and medieval caravanserais, offer a lifetime of discovery in a city of twenty million souls. October through April brings the most tolerable temperatures. Luxor, with its Valley of the Kings, is a short domestic flight or overnight train journey south.

Ha Long Bay is a UNESCO World Heritage landscape of nearly two thousand limestone karst islands rising from emerald waters in Vietnam's Gulf of Tonkin. Must-dos include an overnight junk cruise through the karst formations, kayaking into hidden lagoons, and exploring the cathedral-scale Sung Sot Cave. October through April offers the best weather, with spring mist adding an ethereal quality to the already otherworldly scenery.

Luxor is the greatest open-air museum on earth — the modern city occupying the site of ancient Thebes, capital of Egypt during the New Kingdom's golden age when pharaohs such as Hatshepsut, Tutankhamun, and Ramesses II built temples of a scale and beauty that still stagger the imagination. The East Bank holds the incomparable complexes of Karnak and Luxor Temple; across the Nile, the West Bank conceals the Valley of the Kings, where sixty-three royal tombs were cut into the limestone beneath the pyramid-shaped peak of Al-Qurn. A felucca sunset sail on the Nile, with the cliffs of Thebes glowing amber, is among travel's most transcendent moments. October through April offers the ideal climate.

The Temple of Horus at Edfu is the most completely preserved pharaonic temple in Egypt — a colossus of golden sandstone rising above the Nile's western bank, its towering pylons, hypostyle halls, and sacred inner sanctum surviving almost intact after two millennia beneath the desert. Built between 237 and 57 BC under Ptolemaic rulers, it offers the clearest window into ancient Egyptian temple ritual that archaeology has preserved. The colossal granite statues of Horus at the entrance remain among the most striking sculptures of the ancient world. October through April brings ideal conditions: warm days, cool evenings, and the gentle rhythms of a Nile cruise.

Aswan, Egypt's sunniest city and its ancient southern frontier, offers the Nile at its most scenic — wide, blue, and studded with felucca-dotted islands where temples emerge from the water's edge like visions from another age. The Temple of Philae, rescued from the rising waters of Lake Nasser and reassembled on a new island, is a jewel of Egyptian antiquity; Elephantine Island harbors ruins spanning predynastic times to the Roman era. For the full pharaonic experience, a sunset felucca ride to the Aga Khan Mausoleum rivals any luxury on the Nile. October through April offers the most comfortable temperatures; Abu Simbel is a short flight south.
