Known for its striking handcrafted masks, "Phi Ta Khon" is one of Thailand’s most distinctive cultural traditions, but its significance extends far beyond the colorful procession often seen in photographs.

Held in Dan Sai District, Loei Province, Phi Ta Khon forms part of the annual Bun Luang Festival, a centuries-old tradition that combines Buddhist beliefs, local spiritual practices, and community heritage. The event is closely linked to the Vessantara Jataka, the story of Prince Vessantara, whose return to the city was said to be celebrated by both townspeople and spirits coming out from the forests to join the procession.

Traditionally, the striking Phi-Ta-Khon masks are made from natural materials, including bamboo sticky-rice steamers and carved coconut husks. Each design expresses the creativity and identity of its maker while preserving long-standing cultural traditions. Over time, the designs have become more colourful and creative, while still reflecting the craftsmanship and cultural identity of the local community.

Today, Phi Ta Khon remains one of Thailand’s most important living cultural traditions, preserving local beliefs, craftsmanship, and community heritage as it is passed from one generation to the next. Beyond the iconic masks, the tradition continues through a series of religious ceremonies and community rituals that reflect the close connection between faith, local beliefs, and everyday life in Dan Sai.

For this year, the festival will take place from 20–22 June 2026 in Dan Sai District, Loei Province. While the event spans three days, the famous Phi Ta Khon procession is held only on 21 June, the main ceremonial day. Other key activities include the invocation ceremony for Phra Upakut on 20 June and the Mahachat sermon ceremonies on 22 June, which mark the festival's religious conclusion.
