The second major festival hosted in Ennis is the Bluebonnet Trails Festival, celebrating the state flower of Texas and the vibrant bloom of wildflowers in the surrounding countryside. The event attracts tens of thousands of tourists each year to events including sightseeing excursions and a festival in downtown. The festival is held on the third weekend of April, and the Bluebonnet Trails are hosted for the entire month. First hosted along the Kachina Prairie Park's historic mile-long trail system in 1938, the Bluebonnet Trails have since expanded into a route map of several dozen miles along rural farm roads throughout the surrounding countryside east and northeast of the city. The routes for these sightseeing excursions have been officially hosted and mapped out by the Ennis Garden Club since 1951. To commemorate the popularity of the Bluebonnet Trails Festival and the efforts made to celebrate and preserve the state flower of Texas, Ennis was designated by the 1997 Texas State Legislature as the "Official Bluebonnet City of Texas" and home to the "Official Bluebonnet Trail of Texas."
