The festival is organized in Lam Kinh, Tho Xuan District, Thanh Hoa Province, where Lam Kinh Palace, the mausoleums and tombs of the Le Kings are located here. At the Muc Son Quay, in front of the tomb area in the present-day Xuan Lam Commune, there is a small temple dedicated to King Le Thai To (or Le Loi). In the past, every three years, on the King's death anniversary on the 22nd day of the eighth lunar month, the Le Kings and other mandarins from Dong Kinh (Thang Long - Ha Noi) came here to carry out the ritual. Besides, the local residents hold an annual festival to commemorate the hero at this temple.

Besides the sacrifices- offering ceremony, incense offering rite and other rituals like in many festivals throughout the country, in Lam Kinh Festival, there were ly lien (or ri ren) singing and dances and other performances. Many couples of young boys and girls, hand in hand, danced and sang and performed the game "planting flowers" and "plaiting flowers". Later, these performances were replaced by the ca cong and hue tinh singings and the performances of some stories of Binh Ngo pha tran and Chu hau lai trieu. In the festival, there was also the performance of bronze drums. The festival was attended not only by the Kinh (Viet) people but also other ethnic minorities in Thanh Hoa. On the occasion, they brought and sold in the festival a lot of their forest and native products (bee's honey, aloe wood, cinnamon, mushroom, cat's ear, herbs, etc.) to form a bustling market.
