Top off a day that’s likely to have been filled with one-in-a-lifetime experiences by watching the sun as it dips below the horizon, turning the waters of the Mekong into a vivid masterpiece of orange, red, pink and purple. Soak in the panoramic views of the mountains framed by the changing sky as the sun sets and listen as the villages and towns of the riverside settle down for the evening and a peaceful calm drifts over the countryside.
