What's now one of Southeast Asia's most important archaeological sites was discovered accidentally in 1966 when an anthropology student from Harvard tripped while walking through the area and found the rim of a buried pot right under his nose. Looking around he noticed many more and speculated that this might be a burial site. He was right.
Phu Phrabat Historical Park
No one really knows the history of this mysterious, mystical place peppered with bizarre rock formations. Phu Phrabat is one of Isan's most compelling sights and experiences. The park consists of a collection of strange rock formations that in prehistoric times were modified to form various religious functions.
Wat Pho Chai Sri
With brightly painted statuary that's even more bizarre than Nong Khai's Sala Kaew Ku, this wát is a perfect add-on to Phu Phrabat. The life-size figures around the temple grounds are acting out scenes from Isan fables and demonstrating the punishment awaiting the wicked in the Buddhist Hell.
