New Orleans to Houston Road Trip Guide: Bayous, BBQ & Big Skies

The drive from New Orleans, LA to Houston, TX spans roughly 350 miles along Interstate 10, a route that cuts through Louisiana's swampy bayous and Texas's piney woods before flattening into coastal plains. A little-known fact: the section between Lafayette and Lake Charles follows the exact path of the ancient Teche Ridge, a natural levee from the Mississippi's old delta. This geology explains the subtle elevation changes you'll feel even though the Gulf Coast appears pancake-flat.
