H-E-B Free Fourth Sunday

H-E-B Free Fourth Sunday is the perfect excuse to unleash your inner science nerd and your sense of wonder—all without spending a dime.

Once a month, the Texas Science & Natural History Museum throws open its doors for free admission, turning a regular Sunday into a mini adventure through Texas past and present. From deep time to modern ecosystems, you’ll follow the story of life in the Lone Star State, starting with the birth of our planet and stretching all the way into today’s environment.

• Stand beneath a towering pterosaur with a wingspan longer than a small plane and feel just how massive ancient flying reptiles really were.

• Meet a fearsome tyrannosaur and imagine what it was like to share the landscape with one of Earth’s most iconic predators.

• Marvel at real fossils that capture everything from ancient seas to long-lost giants that once roamed Texas.

• Get up close to Texas wildlife specimens that show off the state’s incredible biodiversity, from tiny critters to big-time predators.

• Hold a piece of outer space in your hands as you touch genuine meteorites and think about just how wild our cosmos really is.

The afternoon is relaxed and family friendly, so you can wander at your own pace, double back to your favorite dinosaurs, or linger under that 33-foot wingspan and soak it all in. Kids can turn their boundless questions into real discoveries, and adults get a chance to reconnect with the kind of curiosity that usually shows up only on nature documentaries.

No tickets, no reservations, no pressure—just four hours of science, history, and “whoa, look at that!” moments. Whether you are a lifelong dino fan, a space enthusiast, or just someone looking for an easy, fun outing, H-E-B Free Fourth Sunday makes it surprisingly simple to turn a regular Sunday into a natural history deep dive.
