Tips for This Route
New Braunfels is worth a detour
If your family wants to extend the trip, New Braunfels sits 30 minutes north of San Antonio and offers Landa Park with playgrounds, paddle boats, and a spring-fed pool. It is one of the best family parks in Central Texas.
I-35 construction between San Marcos and Kyle
TxDOT has ongoing widening projects on I-35 between San Marcos and Kyle. Expect lane shifts and reduced speed zones in this corridor, particularly on weekends when construction crews are active.
Time your departure around San Antonio events
If leaving San Antonio on a weekend, check for Spurs games or downtown festivals. I-35 northbound from downtown can back up significantly when large events let out, adding 20-30 minutes to your departure.
