Visiting the Plain of Jars sites isn't always an easy task, but it's well worth the effort! Dirt paths and rice paddies turn to mud on rainy days, but they also offer some spectacular views as you make your way to the jars.
Archeologists estimate that the jars date from 500 B.C. to 200 A.D. One theory suggests that they may have been used in eleborate burial ceremonies. No one knows for sure, though, why they're scattered across the hills, let alone who put them there in the first place.
HAI JEUAM, the jar in the background, is the biggest at Site 1. It weighs six tons and measures about 8 ft. from top to bottom.
