The biggest and most easily accessible, Site 1 features over 300 jars relatively close-packed on a pair of hilly slopes pocked with bomb craters. The biggest, Hai Jeuam , weighs around 6 tonnes, stands more than 2.5m high and is said to have been the mythical victory cup of Khun Jeuam. The bare, hilly landscape is appealing, although in one direction the views of Phonsavan airport seem discordant. There is a small cafe, a gift shop and toilets near the entrance.
