The Plain of Jars has all the ingredients to stir the imagination

The Plain of Jars has all the ingredients to stir the imagination. Shrouded in mystery and myth, and laced with intrigue and tragedy, this is a bizarre collection of ancient cylinders scattered in their hundreds across the war-scarred countryside of northern Laos's Xieng Khuang province.
Many agents are not willing to commit to a price or even an itinerary until he knows how many tourists will sign up, and he will only know so around 19:00 after the last bus arrives from Vientiane/Vang Vieng/Luang Prabang. A good bet is to ask around to get a feel of which agent you are comfortable with, and return at 19:00 to double-check if he's still doing a group tour the next day. A simple lunch of beef/chicken noodles is usually included in the tour price. Most people like it in Laos tour or Laos tour package.

Should you fail to get into a group tour, agents are willing to do a private tour for 1 tourist in a minibus, but the price vary greatly from 300,000 kip to 500,000 kip or more.
