The sleepy province of Si Sa Ket lies on the Cambodian border. A number of Khmer ruins are located throughout the province, the most famous being Wat Sa Kamphaeng Yai and Noi which date as far back as the 10th century. Just across the border in Cambodia lies Khao Phra Wihan, an Angkor era temple complex which is currently undergoing restoration.
