The Sebastinian Trekkers Club (STC) was founded by 12 college students from the Liberal Arts and Commerce Institute of San Sebastian College – Recoletos de Manila on March 22, 1993 in Famy Siniloan, Laguna,

The STC was officially recognized by the school administration on August 4, 1993.

Since then the STC has helped stimulate among the Sebastinians the importance of preserving our environment, camaraderie among students and the pursuit of dreams and goals in life.
