San Jacinto Family Day: Mapping the Battlefield is a family-friendly day of Texas history at the San Jacinto Battleground in La Porte, just outside Houston. The site is where Texan forces won independence from Mexico in 1836, and the grounds are rich with stories, monuments and open sky. It's a great way to get the kids outside, learn about the land and see the battlefield from a whole new angle. Bring the family, wear comfy shoes and plan to explore at your own pace.
