The Keo pagoda festival is held to commemorate the merit of Master Dương Không Lộ and the people who contributed to the construction of Keo Pagoda.

The festival, in addition to the ceremony, also has many cultural, arts and sports activities such as drum performances, boat races, martial arts performances, tug-of-war, and other folk games.

Keo Pagoda has two festivals, one in spring and the other in autumn. Among the two, the autumn festival is considered as the main event of the year.
