The Old Spanish Trail Association (OSTA) is a non-profit IRS 501(c)(3) volunteer membership organization supported by an Association Manager, its Board, and geographic chapters in different areas (Arizona, California, Colorado, Nevada, New Mexico, Utah, Great Britain), as well as topical chapters, and by members at large.

A director from each trail state, at-large directors, and officers serve on the Board, which meets at least three times a year. OSTA sponsors an annual membership meeting and conference, usually in mid to late summer, which offers formal papers, presentations, field trips along the trail, exchange of ideas and experiences, and making new friends.
