Peñaranda was once known for its high quality crop, the betel leaf locally called ikmo. This leaf is used by older folks as chewing substance. Recently however, the crop is on the brink of extinction. Rice remains a flourishing farm produce.
Every month of May, Peñaranda residents stage a musical drama called “Araquio”, a re-enacment of Christians’ quest led by Queen Helena and King Constantine for the Holy Cross where Jesus Christ was nailed. In this cultural show, actors and actresses garbed in colorful and lively costumes dramatize this century old tradition which features swordfights between Christians and Moors.
Peñaranda is also known for its mouth-watering, native rice cakes such as, espasol, putong puti, bibingka and sapin-sapin.
