[3] The town is famous for its Apung Iru Fluvial Procession, which is listed as one of the most significant water-based intangible cultural heritage of the Philippines where the festival happens every June 28th–30th; and for its blacksmithing.

Apalit received official recognition as a separate town in 1582, while Gonzalo Ronquillo de Penalosa was the country's governor-general at the time.

Capitan del Pueblo Don Pedro Armayan-Espiritu y Macam created the customary fluvial parade of Saint Peter on June 28, 1844, commonly known as "Libad ng Apung Iru," which is still observed today in Apalit during its town festival.

This Barrio was the home of Panday Pira, the first well-known Filipino maker of cannons, and got its name from the Kapampangan word "Palang," which means Bolo or Machete.

After the Spanish conquest of Manila, he worked under Adelantado and Governor General Miguel Lopez de Legaspi, producing "Lantakas" cannons for Rajah Soliman's army.

[5] Apalit is surrounded by Macabebe, Masantol, Minalin and San Simon in Pampanga, and Calumpit, Pulilan, and Baliuag in Bulacan.

In 1597, the Augustinian chapter accepted Apalit as House of Order under the advocacy of San Pedro Apostol where Fray Pedro de Vergara OSA as its first parish priest In conjunction with the annual town fiesta, the Libad was established by the Capitan del Pueblo, Don Pedro Armayan-Espíritu y Macam, on June 28, 1844.Libad fluvial procession also reaching Calumpit even today to signify the old relationship of Apalit to its mother town Calumpit where San Juan Bautista is the patron of the Town.

[12] The Libad, a fluvial procession in honour of the town's patron saint Peter the Apostle (known locally Apung Iru), is annually from 28 to 30 June.

The life-sized, seated image of "Apung Iru" is an heirloom of the Armayan-Espíritu y Macam clan of Sitio Alauli, San Vicente, Apalit.

Custody of the image of Apung Iru has passed to the direct descendants of Don Pedro Armayan-Espíritu y Macam, who married three times: first to Doña Dorotea Arnedo; then Máxima Santa Rita; and finally Ysabel Dungo y Nocom.

In 1928, Doña María translated the image of Apung Iru from the Armayan-Espíritu ancestral home in Sitio Alauli in Barangay San Vicente to her house in Barrio Capalangan, where it has remained since.

The youngest daughter, Doña Elisa Juana "Ising" Arnedo y Espíritu (later Mrs Fortunato Kabiling Sazon) became the next camarera until her death in May 1987.

Doña Elisa's eldest daughter, Dr. Erlinda Crispina "Linda" Arnedo Sazon (later Mrs. Enrique Espíritu Badenhop) succeeded her mother as camarera from until her own death in February 2008.

Public transportation within Apalit, like in most urban areas in the Philippines, is facilitated primarily by inexpensive tricycles, jeepneys, and buses.

In addition, motorized boats (bancas) are used to transport goods and bring people to lower-lying areas in case of floods in other barangays.

Provincial buses, such as Victory Liner and First North Luzon Transit, pass through the MacArthur Highway and transport passengers to various key destinations.
