Far larger than its adjoining Don Det, Don Khon is a peaceful riverine island with fantastic walking and cycling trails. A number of old colonial buildings peppered around its expanse are reminders of Laos’ French connection and add to the island’s old-world charm. Don’t miss a boat trip to see the region’s freshwater Irrawaddy dolphins, as well as a visit to the Li Phi waterfalls, which rush down the Mekong in a powerful set of cascading rapids. The French bridge that runs between Don Khon and Don Det is an excellent spot to watch the sun dip into the horizon at the end of the day, turning the river shimmering shades of gold, pink and red as it falls.
