Scattered across the windswept hills of Xieng Khouang province in northeastern Laos lie thousands of ancient, carved stone vessels known as the Plain of Jars.
01What Are the Jars? Mystery and Theories
Carved from sandstone, granite, and conglomerate rock, the jars range from one meter to over three meters in height and weigh up to several tons.
- The Scientific Consensus: Archaeologists believe the jars were central to Iron Age funerary practices. Excavations have uncovered human remains, burial goods, and ceramics near the jars, suggesting they were used as distillation vessels for temporary ancestral burials before final interments.
- Local Folklore: Local legend tells a more dramatic story: King Khun Jeuam and his army created the jars to brew vast quantities of Lao Lao rice whiskey to celebrate a major military victory over an oppressive warlord.
- Unanswered Questions: Where the stone was quarried, how massive blocks were moved across mountainous terrain without modern machinery, and why the culture vanished remain active archaeological debates.
02Navigating the Jar Sites: Sites 1, 2, and 3
While over 90 jar sites exist across the province, only a handpicked selection is open to visitors due to UXO clearance limits.
- Site 1 (Thong Hai Hin): Overview: The largest, most accessible, and most popular site, located just 15 km southwest of Phonsavan.; Highlights: Features over 300 jars, including the massive 6-ton "King's Jar," an artificial cave used as a crematorium, and an onsite visitor information center.
- Site 2 (Hai Hin Phu Salato): Overview: Situated on two wooded hilltops near Lat Hoang village.; Highlights: Offers a shaded atmosphere where large jars sit carved among tree roots, providing scenic views of farmland below.
- Site 3 (Hai Hin Lat Khai): Overview: Located near Ban Xieng Di village.; Highlights: Reached via a scenic walk across a wooden bridge and through emerald rice paddies, housing around 150 jars spread across a picturesque hilltop.
03The Unexploded Ordnance (UXO) Reality and Safety Rules
Xieng Khouang was one of the most heavily bombed areas on Earth during the Vietnam War era (1964–1973). Understanding UXO safety is mandatory for every traveler.
- Stay Between the Markers: Cleared paths at jar sites are strictly designated by concrete markers in the ground: White Side: Indicates the area inside the white line has been thoroughly swept and cleared of subsurface UXO.; Red Side: Indicates uncleared ground—never step past the red side of a marker.
- MAG Visitor Center in Phonsavan: Before heading out to the sites, visit the Mines Advisory Group (MAG) or UXO Lao information centers in central Phonsavan to learn about the ongoing efforts to clear landmines and submunitions (bombies) across Laos.
- Do Not Touch Metal Objects: If you spot scrap metal or unusual objects while walking near rural villages, do not touch or move them under any circumstances.
04How to Get to Phonsavan and the Sites
Phonsavan is the capital of Xieng Khouang province and serves as the official base camp for exploring the Plain of Jars.
- By Air: Lao Skyway operates domestic flights connecting Vientiane (VTE) to Xieng Khouang Airport (XKH) in Phonsavan, offering a quick 30-minute journey.
- By Bus or Minivan: From Luang Prabang: Minivans run daily along winding mountain highways (approx. 6 to 8 hours).; From Vang Vieng / Vientiane: Buses navigate northern mountain passes, taking between 7 and 10 hours depending on road conditions.
- Local Site Transport: Renting a semi-automatic scooter ($10–$15 USD/day) is popular for visiting Sites 1, 2, and 3 independently. Alternatively, hire a local tuk-tuk or private minivan driver in Phonsavan to cover all three sites in a single day.
05Overview of Key Jar Sites
- Site 1 (Thong Hai Hin): Distance from Phonsavan: 15 km.; Accessibility: Easy (Paved paths, visitor center, paved parking).; Key Features: 300+ jars, King's Jar, natural cave site.

06Weather and Packing Essentials
- Pack for Cool Temperatures: Sitting at over 1,000 meters elevation, Phonsavan is significantly cooler than Luang Prabang or Vientiane. Evenings and early mornings between November and February can drop near freezing (5°C to 10°C), so bring layers and a warm jacket.
- Sturdy Footwear: Closed-toe walking shoes or light hiking boots are essential for walking across uneven grass fields, gravel slopes, and dirt tracks.
- Sun Protection: The high altitude means sun exposure is intense during mid-day walks—carry sunscreen, wide-brim hats, and plenty of water.
