In the southern region of Champasak Province the Mekong River flows through a riverine archipelago which name is Laotian means “The 4000 Islands”. Si Phan Don is a labyrinth of islets, rocks and sandbars located just above the border with Cambodia. A very laid-back atmosphere and infinity of waterways permeate the area, giving room to activities like swimming, tubing, boat cruises, kayaking and cycling.
As expected the mighty Mekong plays a vital role in the lives of the locals with 95% of the families fishing to supplement their income. The remains of the Don Det – Don Khon narrow gauge railway built by the French Mekong Exploration Commission and operating from 1893 to 1949 can still be seen in these islands.
Southeast Asia’s largest waterfalls are located in Si Phan Don and the endangered species of freshwater Irrawaddy dolphins can also be viewed by boat off Don Khong, arguably the most developed place among all the islands.
