Tak is famous for its Loi Krathong Sai or the floating of a thread of krathongs made from coconut shells, a local wisdom that has been passed through generations.
Each year, Tak will celebrate the annual Loi Krathong Sai along with the competition of floating a train of 1,000 glittering lanterns or coconut-shell krathongs for a royal trophy. The festival normally begins with a day of traditional procession of krathongs.
