Vangvieng, actually there's a lot of thing to do to enjoy such as Tubibg Kayaking along the Namsong and caviviting, bking rock clibing etc... The authority has only closed the Bars along numsong river selling illegl items. When the restuarant is closed you can choose to visit Tham lom cave. I stronmgly support the authorities in doing so. Because all good things (images and nature) might again regenerate.
