Head up Nam Xay Viewpoint for an awe-inspiring panoramic view of Vang Vieng's lush rice fields and jagged limestone cliffs. Though there are bamboo platforms and huts constructed, the viewpoint is not widely known, thereby allowing you to marvel undistrubed at the breathtaking scenery. The 20-minute hike is relatively easy and supplemented by railings and steps, but can be tricky after the rain.
