Bun Bang Fai, Chiang Mai’s Rocket Festival 

Every year, as the scorching heat of Thailand’s dry season begins to wane, the northern city of Chiang Mai comes alive with the vibrant and thunderous celebration of the Bun Bang Fai, or Rocket Festival. Held annually in May, this festival marks the arrival of the rainy season, ensuring fertile lands for the upcoming rice planting. In 2025, the festival is set to take place from May 8 to May 10.

Bun Bang Fai

A Skyward Tradition Rooted in Ancient Beliefs

The origins of Bun Bang Fai trace back centuries, intertwining with ancient fertility rites and Buddhist traditions. Historically, the festival was believed to appease Phaya Thaen, the God of the Sky, who had withheld rain for seven years, leading to drought and famine. In response, the Toad King, Phaya Khang Khok, led a celestial battle to restore the rains, culminating in a peace treaty that promised annual rainfall. To remind Phaya Thaen of his commitment, villagers launched bamboo rockets into the sky, a practice that continues today .​

The festival’s name, “Bun Bang Fai,” reflects its purpose: “Bun” meaning merit-making, “Bang” referring to bamboo, and “Fai” meaning fire. Villagers construct and launch these rockets as acts of devotion, hoping to secure blessings for a bountiful harvest.​

Crafting the Rockets: A Labor of Love

Constructing a Bang Fai rocket is no small feat. Villagers dedicate days to crafting these towering bamboo cylinders, some reaching up to nine meters in length and weighing over 120 kilograms. The process involves selecting straight bamboo, boiling it to eliminate insects, and carefully packing it with gunpowder. The rockets are then mounted on carts or traditional wooden frames and adorned with vibrant decorations.

The competition is fierce, with categories based on size and power. Judges assess the rockets on their altitude, distance, and the beauty of their smoke trails. A misfired rocket can lead to playful consequences, such as the builder being covered in mud, symbolizing both a humorous tradition and a safety measure.
