Deep in the far south of Laos, just before the river crosses into Cambodia, the mighty Mekong reaches its widest point and shatters into a labyrinth of thousands of islands, sandbars, and cascading waterways known as Si Phan Don. This premium itinerary is an invitation to step completely off the grid and experience a world dictated entirely by the gentle flow of the river. You will base yourself at a luxury eco-resort on the tranquil islands of Don Det or Don Khone, where the French colonial past still echoes through rusted railway tracks and vintage architecture. Explore peaceful fishing villages by bicycle, cruise through narrow river channels on a private boat to spot the critically endangered Irrawaddy dolphins, and marvel at the thunderous, wide cascades of the Khone Phapheng waterfalls. This is a sanctuary crafted for those who want to see nature in its rawest, most peaceful form without sacrificing premium comfort.
