The Texas Triangle: Houston, Dallas, Austin & San Antonio
The Texas Triangle links the state's four great cities — Houston, Dallas-Fort Worth, Austin, and San Antonio — in one 750-mile loop of fast interstates, world-class barbecue, and wildly different city personalities. It's the rare American road trip where the driving is easy and the destinations do the work.
The Loop
| Leg | Distance | Drive Time |
|---|---|---|
| Houston → Dallas | 240 mi | ~3h 30m |
| Dallas → Austin | 195 mi | ~3h |
| Austin → San Antonio | 80 mi | ~1h 30m |
| San Antonio → Houston | 200 mi | ~3h |
No leg exceeds four hours, so you can base a full day in each city and still never drive after dark. I-45, I-35, and I-10 carry the loop; the only traffic worth planning around is Austin's I-35 corridor (brutal 7-9 AM and 4-7 PM) and Houston's rush hours.
City by City
Houston
Space Center Houston is the anchor attraction — allow half a day. The Museum District packs 19 museums into a walkable park zone, and the city's food scene (Viet-Cajun crawfish, Tex-Mex, top-tier barbecue at Truth BBQ) is arguably the state's best.
Dallas–Fort Worth
In Dallas: the Sixth Floor Museum at Dealey Plaza and the Arts District. In Fort Worth, 35 miles west: the Stockyards' twice-daily cattle drive and the Kimbell Art Museum. The two cities are different trips wearing one metroplex.
Austin
Break the Dallas-Austin leg in Waco (Magnolia Market, the Dr Pepper Museum). In Austin: the Capitol, Barton Springs' 68-degree spring-fed pool, the Congress Avenue bat colony at dusk (March-October), and live music on Rainey Street. Franklin Barbecue rewards those in line by 9 AM.
San Antonio
The Alamo and the River Walk are the postcard stops, but the real gem is the San Antonio Missions National Historical Park — four Spanish missions along a bikeable riverside trail, a UNESCO World Heritage site.
Detours Worth Adding
- Texas Hill Country: Between Austin and San Antonio via US-290 and TX-16 — Fredericksburg's wineries, Luckenbach's dance hall, and swimming holes like Hamilton Pool (reserve ahead).
- Lockhart: 30 minutes from Austin, the Barbecue Capital of Texas. Pick any of the big three smokehouses; you can't lose.
- College Station: On the Houston-Dallas leg, home of the George H.W. Bush Presidential Library.
When to Go
March-April (bluebonnet season lines the highways in wildflowers) and October-November are ideal. Summer is 95-105°F everywhere — doable, but plan pools and museums for afternoons. Winter is mild and cheap.
Frequently Asked Questions
The loop itself is about 750 miles and 11-12 hours of total driving. Four days (one night per city) is the minimum; six days lets you add the Hill Country between Austin and San Antonio.
Any order works since it's a loop. A common plan: start in Houston, drive up I-45 to Dallas, down I-35 through Waco to Austin, on to San Antonio, then back to Houston on I-10 — putting the barbecue corridor and Hill Country in the middle of the trip.
Lockhart, 30 minutes south of Austin, is the officially designated 'Barbecue Capital of Texas' (Black's, Kreuz, Smitty's). In Austin itself, Franklin Barbecue's line is legendary — arrive before 9 AM.
