The Si Phan Don (meaning The 4000 islands) is a riverine archipelago located in the Mekong River, Champasak Province in southern Laos. Si Phan Don is characterised by numerous islands, half of which are submerged when the Mekong River is in flood. The principle islands of Si Phan Don are Don Khong (the largest), and Don Det and Don Khon.
You may catch the boat to Done Khone (the 4,000 islets) to visit the impressive Liphi Waterfall (Devil Corridor). If you are lucky you can enjoy watching the Irriwady dolphins and the remnants of the French colonial area (old pier, stream rail way, former French building and Maritime Office). There are many villages in the surrounding regions where you will experience the authentic culture of Laos.
Liphi Waterfall or Devil Corridor is one of the most impressive waterfalls in Laos. Here, you can enjoy swimming, sun baking on the sandy beach and watching the rare Irrawaddy Dolphins.
