Si Phan Don

The Si Phan Don (Lao: ສີ່ພັນດອນ; meaning '4,000 islands') is a riverine archipelago in the Mekong River, Champasak Province in southern Laos.

Si Phan Don is dotted with numerous islands, half of which are submerged when the Mekong River is in flood.

Pakse is the closest of the bigger cities in Laos to the area.

Key features of the Si Phan Don archipelago include: In the past, timber was logged on the islands, but it is now regulated; illegal logging incurs stiff penalties.

While the local economies are predominantly based on agriculture, the Si Phan Don archipelago has seen an increasing number of visitors.
