Experience Hanoi, Hue, Halong Bay and the unspoiled paradise of Phong Nha-Ke Bang National Park. Vietnam has hundreds of miles of beautiful coastline, but it’s mostly the local fisherman who get to see it. This new small-ship adventure cruise offers a chance to experience it in a way few tourists have. Starting in Hanoi, visit not only Halong Bay, historic Hue, and the important war sites of Vinh Moc and Khe Sanh, but also the largely unknown natural paradise of Phong Nha-Ke Bang National Park. This immense, unspoiled haven takes the ancient limestone scenery to the next level – or more precisely, underground. If there’s one natural wonder to see in Vietnam before it changes, this is the one.
