Welcome to OSTA!

An important part of OSTA’s efforts has been consulting with the federal administrators for the Trail – the Bureau of Land Management (BLM) and the National Park Service (NPS) – on a management plan, required by the National Trails System Act. That plan is intended to guide the administration and management of the Trail on federal public lands, and on state, tribal, and local government lands, and private lands through cooperative efforts with such entities and individual landowners. After 15 years of prolonged planning and discussions the BLM and NPS have released a Comprehensive Administrative Strategy for the Trail.

The Old Spanish Trail Association, its members, friends, and partners are dedicated to protecting, interpreting and promoting the Old Spanish National Historic Trail.

The Old Spanish National Historic Trail was established by Congress in 2002. It has often been referred to as the most arduous, difficult trail in the United States. Its designated routes cover six states and some 2,700 miles, traversing mountains, deserts, rivers, and coastal valleys. It was historically used by curious and brave, enterprising, and sometimes nefarious men, forging trade routes between the Mexican cities of Santa Fe, New Mexico, and Los Angeles, California.  New Mexican woolen goods were traded for California mules and horses, but the trade also included furs, hides, and even Indian slaves.
