TETRA has trails rides across the state of Texas, which is the second largest US state with an area of 261,797 square miles, and has 254 counties.  Due to the size of our state, TETRA is organized into 12 Regions representing members in each region.  You do not have to be a member to attend any of our functions, but becoming a member of TETRA helps keep the momentum alive as we work with the Corps of Engineers and Texas Parks to better the riding facilities of Texas.

A Regional Director hosts trail rides throughout the year. Besides trail riding TETRA has other regional activities some such as hosting a work day to clean trails of the local equestrian facility, clinics, and meetings. For more information about your region please visit that region's page.
