Dallas to Austin: Three Good Stops Down I-35

About 195 miles from downtown Dallas to the Capitol in Austin, all of it on I-35, the busiest and most complained-about road in Texas. Here is where we get out anyway: a Czech bakery that never seems to close, a dig site where a herd of Ice Age mammoths still lies where it fell, and a cave that was discovered by the crew building the interstate.
- 195 miles · one interstate the whole way
- 3 hr 10 min driving with clear roads · plan on more
- I-35E S · I-35 S from Hillsboro
- Blackland Prairie to the edge of the Hill Country
There is no scenic way to say it: this is I-35, and I-35 is a working road. It carries trucks between Mexico and the Midwest and commuters between four fast-growing metro areas, and there has been construction somewhere along it for as long as anyone can remember. The good news is that the drive is short, and the stops along it are better than the road's reputation.
Out of Dallas you take I-35E south through the suburbs and into open farm country. At Hillsboro, about 60 miles in, it joins I-35W from Fort Worth and becomes plain I-35 for the rest of the trip. From there it is flat, black-soil prairie past Waco and Temple, and the land only starts to roll as you near Georgetown, where the limestone edge of the Hill Country begins.
Timing matters more than on most drives. Leaving Dallas before 7 or after 9 on a weekday avoids the worst of the northern end, and the last 30 miles into Austin can crawl any afternoon from about 3:30 onward. If you can, arrive in Austin before then or after 7.
Stop 1 — The Czech Stop, West
Mile 75 · right at exit 353 · 20 to 30 minutes
Czech immigrants settled this part of the prairie in the late 1800s, and the little town of West (the name is just West) still calls itself the Czech Heritage Capital of Texas. For drivers, that heritage comes down to one thing: kolaches, soft sweet-dough pastries filled with fruit, cream cheese or poppy seed, and their savory cousins stuffed with sausage and cheese.
The Czech Stop, a bakery and gas station right at the exit, has been the traditional place to buy them for decades and keeps famously long hours. Expect a line on weekend mornings; it moves fast. Buy a mixed dozen, eat two in the parking lot, and keep the rest for the car. It is the rare road-trip stop that Texans from both ends of the drive agree on.
If you have an extra half-hour: drive five minutes into West's old downtown along Oak Street, where a few more bakeries and a Czech-American museum line the main street.
Stop 2 — Waco Mammoth National Monument
Mile 95 · about 10 minutes off I-35 · 1 to 1.5 hours
In 1978 two young men searching for arrowheads along a creek outside Waco found a large bone sticking out of the bank. It belonged to a Columbian mammoth. Excavation over the following decades uncovered the remains of about two dozen of them, and scientists believe many were a nursery herd — females and young that died together, probably in a flood, tens of thousands of years ago. It is the only site of its kind known in the country, and it became a national monument in 2015.
The heart of the visit is the dig shelter, a climate-controlled building over the excavation. A guided tour walks you onto a raised platform above the pit, where the bones lie exactly as they were found in the ground, including a bull mammoth and a camel that died on the same spot. Tours run on a schedule and there is a modest admission fee, so check times and arrive a little early. The short trail from the welcome center winds through shady woods along the creek.
If you have an extra hour: Waco has two more stops everyone asks about. Magnolia Market at the Silos, the shop and garden built by the hosts of the TV show Fixer Upper, is downtown near the interstate, and the Dr Pepper Museum sits in the old bottling plant a few blocks away — the drink was invented at a Waco drugstore in the 1880s.

Stop 3 — Inner Space Cavern, Georgetown
Mile 165 · right at exit 259 · 1 to 1.5 hours
In 1963 a Texas Highway Department crew was drilling test holes to plan an overpass for the new interstate when the drill bit dropped into empty space. Below the highway route lay a cave system nobody knew was there. A worker was lowered down the shaft to look, and three years later Inner Space Cavern opened to the public. You still enter it right beside I-35, and the traffic you just left rolls along almost directly overhead.
Guided walking tours take you through big rooms of stalactites, flowstone and soda-straw formations on lit, paved paths. Along the way the guides point out where researchers found the bones of Ice Age animals that fell or washed into the cave, mammoths among them — a neat echo of the Waco stop an hour back up the road. It stays cool and humid underground all year, which makes it the best hour you can spend on a Texas summer afternoon. Book a tour time ahead on busy weekends.
Why we put it last: it sits just 28 miles short of downtown Austin, so you can time your exit to slip in after the afternoon rush. If you have more daylight, Georgetown's courthouse square, a few minutes west, is one of the prettiest in the state.
Arriving in Austin
I-35 runs straight through downtown Austin, past the University of Texas and within a few blocks of the pink-granite Texas State Capitol, which is free to tour and taller than the U.S. Capitol. From March through October, go to the Congress Avenue Bridge at dusk, where a huge colony of Mexican free-tailed bats pours out from under the bridge over Lady Bird Lake. South Congress, just across the river, is the easiest evening walk for food and music. For tours and tickets around town, book Austin tours and tickets ahead; for a story you can walk at your own pace, there is a self-guided audio walk downtown.
How we would time it
Leave Dallas by 9, after the morning rush. Kolaches at the Czech Stop around 10:15. The Waco Mammoth site from 11 to 12:30, then lunch in Waco. Back on I-35 by 1:45, gas in Temple, and Inner Space Cavern at 3. Out by 4:30 and into Austin as the traffic allows — with a sunset walk to the bat bridge if the season is right.
Booking the rest of it
Both Dallas airports and Austin's have plenty of rental cars, and one-way rentals between the two cities are common. Compare EconomyBookings and GetRentacar. Downtown Austin parking is expensive, so if you are staying downtown, ask the hotel about parking before you book.
The three stops on a map
Stops in driving order. Map data © OpenStreetMap contributors.
How far is Dallas to Austin and how long does it take?
About 195 miles and 3 hr 10 min of driving on I-35E and I-35 with clear roads. Traffic around Dallas, Waco construction zones and the northern approach to Austin often push it to 3 hr 45 min or more, especially on Fridays.
What are the best stops between Dallas and Austin?
The Czech Stop in West, famous for kolaches, right at exit 353; Waco Mammoth National Monument, about 10 minutes off I-35, where a herd of Ice Age mammoths lies in a covered dig site; and Inner Space Cavern in Georgetown, a cave found by a highway crew in 1963, right at exit 259.
Where do people buy kolaches between Dallas and Austin?
In West, Texas, about 75 miles south of Dallas. The Czech Stop at exit 353 is the best-known bakery, and a few more are in West's small downtown.
Is Waco Mammoth National Monument worth the stop?
Yes. It is only about 10 minutes off I-35, the visit takes an hour or so, and the guided dig-shelter tour lets you look down on mammoth bones exactly where they were found. There is a modest admission fee and tours run on a schedule.
What is the best time to drive I-35 from Dallas to Austin?
Mid-morning on a weekday. Leave Dallas after about 9 to miss the morning rush and aim to reach Austin before 3:30 or after 7 to avoid the evening backup.
