Unravel the mysteries of Vietnam on a Holland America Line cruise to Asia. You can tour the Nha Trang market before a hands-on cooking class, or gain access to the infamous Cu Chi Tunnels and Ho Chi Minh City (aka Saigon) from Phu My. Ride a rickshaw through Da Nang, or venture beyond to imperial Hue, timeless Hoi An — a UNESCO World Heritage Site — and the oft-painted Marble Mountains. Cruise UNESCO-designated Halong Bay aboard a converted junk, or visit Vietnam’s buzzy capital, Hanoi.
