Science Mill

Science Mill in Johnson City, Texas is one of the Texas Hill Country's most celebrated educational destinations — an award-winning science and technology museum housed in a beautifully restored 1880s grist mill, blending authentic Texas history with cutting-edge interactive STEM exhibits.

With 984 Google reviews at an impressive 4. 7-star rating, Science Mill consistently earns exceptional marks from both local families and visitors discovering it during Hill Country road trips. The combination of a remarkable historic setting — the actual operating mill building is preserved and integrated into the exhibit experience — and high-quality science content creates something genuinely unusual in the museum world.

The exhibits span technology, engineering, biology, and earth science with an emphasis on hands-on learning. Outdoor exhibit areas extend the experience into the surrounding Hill Country landscape. For kids ages 5-17, the engaging design successfully bridges the gap between 'educational' and 'actually fun.'

Practical planning note: Science Mill is only open Wednesday through Saturday (closed Sunday, Monday, Tuesday). Hours end at 4PM. These limited days require deliberate scheduling. If you're planning a Texas Hill Country road trip from San Antonio, the 1-hour drive to Johnson City makes this a natural stop.

Johnson City is also LBJ's hometown, with the Lyndon B. Johnson National Historical Park nearby. Enchanted Rock State Natural Area is a short additional drive. These combinations make a well-designed 2-day Hill Country itinerary possible.
