Day Trips from San Antonio

Hikers dotting the bare pink granite dome of Enchanted Rock above scrub and boulders, one of the best day trips from San Antonio
Enchanted Rock in late November 2024. The small specks on the skyline are people, which tells you something about the scale and about the crowds.

The best day trips from San Antonio are New Braunfels and Gruene for river floats and dance-hall music, about 40 minutes up I-35; Fredericksburg for German Hill Country streets and the National Museum of the Pacific War, about 80 minutes; Enchanted Rock for a climb up a 425-foot granite dome, just under two hours; and Lockhart for barbecue, a little over an hour. Castroville and Boerne are the easy half-days, Lost Maples is the fall-color trip, and the caves are what you do when it’s 100°F.

This guide is for visitors with a car and a free day who want to choose well rather than choose everything. The caveat is that the popular state parks now fill up: Enchanted Rock and Lost Maples both ask you to reserve a day pass to guarantee entry, and Lost Maples reaches capacity every day in October and November. Drive times are free-flow figures from Alamo Plaza, and I-35 is rarely free-flowing. Prices, hours and rules were checked September 23, 2026 against Texas Parks and Wildlife, the Texas Historical Commission, the City of New Braunfels and the operators themselves.

Drive times come from OpenStreetMap routing run on September 23, 2026. Treat them as the floor. Weekend traffic on I-35 toward New Braunfels and on I-10 toward Boerne can add 20 minutes or more, and Hill Country two-lane roads are slower than any routing engine thinks. For more close-to-town ideas, our guide to things to do in San Antonio covers what’s inside the city limits.

How to Choose the Right Day Trip

Start with what you want the day to feel like, then check the season. A river day in July is a great idea at 10 a.m. and a grim one on an exposed granite dome at 2 p.m.

Do You Need a Car for Day Trips?

Yes, for all but one. No public transit reaches Fredericksburg, Gruene, Boerne, Bandera or the state parks in any way you’d want to rely on. Austin is the exception, because Amtrak’s Texas Eagle runs daily between San Antonio and Austin on its way to Dallas and Chicago, though a single train each way won’t suit every schedule. Your other option is a guided tour that includes transport. Our guide to getting around San Antonio covers renting a car for a single day at the airport, which is usually cheaper than keeping one all week.

Under an Hour: New Braunfels, Gruene, Boerne and Castroville

New Braunfels and the Comal River

German settlers founded New Braunfels in 1845, and the town sits in Comal County, not Bexar, a detail that matters only when you’re reading the local news. For visitors it means one thing: the Comal River, short, spring-fed and clear, with a tubing culture that takes over summer weekends. The City of New Braunfels keeps the Comal open for recreation except during high water. At 100 to 500 cubic feet per second, all activities are open; from 500 to 600 the city says to use extreme caution; at 600 and above it closes public access temporarily. Lifeguards work the City Tube Chute on weekends in May and daily from June to mid-August, and not at all after Labor Day. River parking is paid, and the city publishes a list of what you can and can’t bring on the water, so read it before you pack a cooler.

The Comal in Landa Park. The water is spring-fed, which is why it stays clear and why summer weekends get so busy.

Outside tubing season, New Braunfels is a pleasant town with parks along the river. Schlitterbahn’s original water park is here too, now run under Six Flags; check its season calendar before planning around it.

Plan it: 31 miles, about 39 minutes free-flow on I-35, often longer. Check the real-time river flow on the city’s Comal River page the morning you go. Arrive before 10 a.m. on summer weekends for parking. A separate guide covers a full New Braunfels day.

Gruene

Gruene (pronounced “green”) is a historic district on the Guadalupe River at the north edge of New Braunfels, and its anchor is Gruene Hall. Built in 1878, it bills itself as Texas’ oldest continually operating dance hall: 6,000 square feet under a tin roof, side flaps that open for air, a bar at the front, a small stage at the back and a big outdoor garden. There’s live music every day, from afternoon sets to ticketed shows with names you’ll know. The surrounding streets are a short loop of old buildings, shops and restaurants, and the Guadalupe below is a floating river when conditions allow.

Plan it: 35 miles, about 46 minutes free-flow. Free to wander; check Gruene Hall’s calendar and buy tickets ahead for headliners. Pair it with New Braunfels for a full day, or make it an evening trip for a show. Allow for weekend crowds and tight parking in the district.

Boerne

Boerne (pronounced “bernie”) is the closest Hill Country town up I-10, 31 miles from the Alamo, with a walkable Main Street, a creek and a lower-key feel than Fredericksburg. The strongest reason to go is Cave Without a Name, a show cave northeast of town with hour-long guided tours through six major rooms on concrete and gravel paths, at a steady 66°F. Tours cost $23 for adults and $11.50 for children 6 to 12, plus tax, and children under 6 are free. It opens daily, 10 a.m. to 5 p.m. from Labor Day to Memorial Day, with the last tour at 4, and 9 a.m. to 6 p.m. in summer. It’s closed on Thanksgiving and Christmas, and it asks you to reserve.

Plan it: 39 minutes free-flow to Main Plaza; the cave is 41 miles and about 67 minutes from Alamo Plaza on slower back roads. Do the cave at midday in summer and the town in the morning or evening. Guadalupe River State Park is nearby if you want a river afternoon.

Castroville

Castroville calls itself the Little Alsace of Texas, and it earns the name more honestly than most slogans. Henri Castro planned the town in 1844 and settled it largely with families from Alsace, on the Medina River 26 miles west of the Alamo. The Landmark Inn State Historic Site, run by the Texas Historical Commission, tells the story of migration, industry and preservation on the riverbank. It’s open daily from 9 a.m. to 4:30 p.m., and admission is $5 for adults, $3 for seniors, veterans, teachers and first responders, and $2 for ages 6 to 17. The streets around it hold small stone and timber houses in a style you won’t see in San Antonio.

Plan it: 33 minutes free-flow west on US 90. A half-day trip, and the easiest one on this page. Good for a morning when you don’t want to fight I-35.

An Hour to Ninety Minutes: Fredericksburg, Lockhart, Bandera and Canyon Lake

Fredericksburg

Fredericksburg is the classic Hill Country day trip, and it’s popular for good reason. German settlers founded it in 1846, and the long Main Street still reads as a 19th-century town, now lined with shops, restaurants and tasting rooms. Wineries spread along US 290 east of town. The standout sight is the National Museum of the Pacific War, a Texas Historical Commission property run by the Admiral Nimitz Foundation in the hometown of Fleet Admiral Chester Nimitz. It covers the war in the Pacific seriously, with galleries, a Japanese Garden of Peace and the Pacific Combat Zone.

Plan it: 70 miles, about 80 minutes free-flow via I-10 and US 87. The museum is open 9 a.m. to 5 p.m. Wednesday to Monday and closed Tuesdays; the Pacific Combat Zone closes at 3 p.m. Tickets are $26 for adults, $20 for seniors, $18 for military, $12 for students and free for children 9 and under and WWII veterans. Give the museum three hours or more. If you drink at the wineries, bring a designated driver or book a tour, because the drive back is long. Our separate Fredericksburg guide covers the town in detail.

Lockhart

Lockhart, in Caldwell County southeast of Austin, is a barbecue pilgrimage. The Texas House in 1999 and the Senate in 2003 passed resolutions naming it the Barbecue Capital of Texas, and the big names are within a few blocks of the ornate Caldwell County Courthouse. Kreuz Market, at 619 N. Colorado St., serves meat-market style barbecue Monday to Saturday from 10:30 a.m. to 8 p.m. and Sunday until 6. Smitty’s Market works out of Kreuz’s old building on South Commerce Street, where it has been since 1999, and Black’s Barbecue on North Main has been in the same family since 1932. Chisholm Trail Bar-B-Q rounds out the classic four. Expect to order by the pound at a counter, meat-market style, which is the tradition these places grew out of, and to eat off butcher paper rather than a plate.

Plan it: 67 miles, about 73 minutes free-flow. Go for lunch and get there early, since popular cuts can sell out. Eating at two places is traditional; eating at four is ambitious. Check each restaurant’s hours before you drive. For San Antonio’s own barbecue and Tex-Mex, see our San Antonio food guide.

Bandera

Bandera markets itself as the Cowboy Capital of the World, and the county’s ranches, rodeo arenas and dude ranches back it up. In town, the Frontier Times Museum, a block north of the courthouse at 510 13th St., holds a collection started in 1933 by the journalist and historian J. Marvin Hunter, now more than 40,000 items on cowboys, rodeo champions and ranching, plus a Western art gallery. It’s open Monday to Saturday from 10 a.m. to 4:30 p.m.; confirm before you go. The Medina River runs along the edge of town.

Plan it: 47 miles, about 66 minutes free-flow on two-lane roads. A half day on its own. It works best combined with a ranch activity or as a stop on the way to Lost Maples, which is further west.

Canyon Lake and the Canyon Lake Gorge

Canyon Lake is a reservoir on the Guadalupe north of New Braunfels, with parks and boat ramps around its shore. The reason to come as a day-tripper is the Canyon Lake Gorge, a canyon carved into the limestone below the dam when floodwater poured over the spillway in 2002, now managed by the Guadalupe-Blanco River Authority. You see it two ways. Guided public tours go into the gorge itself, by online request only. The self-guided Gorge Rim Trail needs no reservation and costs $5 per person age 12 and up. From September 8, 2026 the site opens Monday to Saturday from 9 a.m.

Plan it: 47 miles, about 65 minutes free-flow. Request a guided tour well ahead, since that’s the part that shows the fossils and exposed rock. Pair it with Gruene, a short drive down the river.

Also up I-35: San Marcos and Wimberley

San Marcos (49 miles, about 57 minutes free-flow) and Wimberley (62 miles, about 77 minutes) are the other river towns north of New Braunfels. Both draw summer swimmers, and some of their best-known swimming spots use seasonal fees or reservations that change from year to year, so check the city or operator’s site before you go. Both pair more naturally with an Austin trip than with a Hill Country loop.

State Parks and Natural Areas: Reserve Your Day Pass

Texas state parks sell day passes online, and at the popular ones a reservation is the difference between hiking and turning around at the gate. If you plan to visit several parks, the Texas State Parks Pass costs $70 a year and covers entrance for you and your guests at more than 80 parks.

Enchanted Rock State Natural Area

Enchanted Rock is a 425-foot dome of pink granite north of Fredericksburg, with 22 miles of trails including the steep Summit Trail. Its name comes from old stories about the rock, and Texas Parks and Wildlife’s own page acknowledges the legends; the climb is the part that’s real. The busy season runs September through May, and the park asks you to reserve day passes online or by phone at (512) 389-8900 to guarantee entrance. Entry is $8 for adults and free for children 12 and under.

Plan it: 87 miles, about 1 hour 51 minutes free-flow. The park opens at 6:30 a.m. and the gate closes at 8 p.m.; trails run from half an hour before sunrise to half an hour after sunset, with the Loop Trail open until 10 p.m. Bring your own drinking water, because the park says it’s in short supply during the drought. The Summit Trail can close in wet weather, and granite gets slippery. In summer, climb at first light or don’t climb. Pets are allowed only in designated areas.

Guadalupe River State Park

With four miles of river frontage, this is the swim-and-tube park closest to the city. You can swim, fish, tube and canoe, and there are 13 miles of hike and bike trails away from the water. Styrofoam and glass are banned along the riverbanks and in the river. The park also has an all-terrain wheelchair available to use, which is worth asking about ahead.

Plan it: 40 miles, about 56 minutes free-flow. Adults pay $7 a day, children 12 and under are free, and day passes can be reserved online, which matters on summer weekends. Check river conditions with the park before a paddling trip.

Lost Maples State Natural Area

Lost Maples is famous for bigtooth maples that turn red and orange in autumn, rare this far south and the closest thing Central Texas has to leaf-peeping. The park is candid that the show varies with the weather, and it starts publishing a fall foliage report in mid-October. It’s also a good hike the rest of the year, with more than 10 miles of trails, limestone canyon walls and the Sabinal River.

Plan it: 86 miles, about 1 hour 53 minutes free-flow, near Vanderpool. Open daily 8:30 a.m. to 4:30 p.m.; $6 for adults, free for 12 and under. October and November are the busiest months, and the park reaches capacity daily, so reserve your pass to guarantee entry. There’s no cell service in the park, so download maps first. Stay on trails: the maples have shallow roots.

Further out: Garner State Park

Garner State Park on the Frio River is about 91 miles and two hours from the Alamo. It’s a summer swimming favorite, but at four hours of round-trip driving it makes more sense as an overnight than a day trip.

Caves: The Day Trip for a 100°F Afternoon

San Antonio averages 92 to 96°F highs from June through August, and underground is where you want to be. Two show caves are within an hour.

CaveFrom the AlamoCost (Sept. 2026)Tour lengthGood for
Natural Bridge Caverns27 mi, 37 min free-flowTours from about $25 for adults, prices change daily; parking $10Varies by tourThe bigger, busier choice, with several tour types
Cave Without a Name41 mi, 67 min free-flow$23 adults, $11.50 ages 6 to 12, under 6 free, plus taxAbout an hour, a quarter mile undergroundA quieter, smaller operation at a steady 66°F

Natural Bridge Caverns sits off I-35 north of the city, about 30 minutes from downtown by its own reckoning, and it’s covered in our San Antonio theme parks and attractions guide alongside the other big family draws. Cave Without a Name pairs naturally with Boerne. Both are good rainy-day options too.

Bigger Cities: Austin, Corpus Christi and Houston

Austin is 79 miles and about 92 minutes free-flow from the Alamo, and I-35 between the two cities can easily add an hour. As a day trip it’s doable, especially by Amtrak, but the city deserves more than a day. Corpus Christi is 143 miles and about two and a half hours down I-37, which means five hours of driving for a beach day; make it an overnight. Houston, at 195 miles and almost three and a half hours, isn’t a day trip at all.

Which Day Trips Pair Well Together?

Two Sample Day-Trip Plans

Timing makes or breaks a Hill Country day. These two plans show how to fit the heat, the reservation rules and the opening hours together; swap in your own stops.

A summer river day: New Braunfels, a cave and Gruene

  • 7:30 a.m. Leave downtown and take I-35 north before weekend traffic builds. Check the Comal’s real-time flow on the City of New Braunfels site before you go; at 600 cubic feet per second or more, public access closes.
  • 8:15 a.m. Park near the river (it’s paid parking) and get on the water while it’s cool and before the crowds. Lifeguards staff the City Tube Chute daily from June to mid-August.
  • Noon. Lunch in the shade in New Braunfels.
  • 1:30 p.m. Head back south to Natural Bridge Caverns, off I-35 on the way to San Antonio, and spend the hottest part of the day underground. Prices change daily, so book online, and budget $10 for parking.
  • 6:00 p.m. Drive north again to Gruene for dinner and a show at Gruene Hall, then back downtown after dark, about 46 minutes free-flow.

That’s a long day with a lot of I-35. Families with young children should pick two of the three stops, not all of them.

A fall hike and history day: Enchanted Rock and Fredericksburg

  • 6:00 a.m. Leave downtown with a reserved Enchanted Rock day pass for today’s date. It’s just under two hours in free-flowing traffic.
  • 8:00 a.m. Climb the Summit Trail while the granite is cool and the parking lot is still half empty. Carry your own water.
  • 11:00 a.m. Drive south into Fredericksburg for lunch on Main Street.
  • 12:30 p.m. Start at the National Museum of the Pacific War’s Pacific Combat Zone, which closes at 3 p.m., then move on to the main galleries until the 5 p.m. close.
  • 5:00 p.m. Either visit a tasting room on US 290 with a designated driver, or start the 80-minute drive home.

Don’t try this plan on a Tuesday, when the museum is closed, or after heavy rain, when the Summit Trail can close.

The Best Day Trips by Season

SeasonBest choicesWhy
Spring (March to May)Fredericksburg, Enchanted Rock, Bandera, CastrovilleMild temperatures, roadside wildflowers and the tail of Enchanted Rock’s busy season
Summer (June to August)New Braunfels, Guadalupe River State Park, the cavesWater or underground; skip the granite dome after mid-morning
Fall (September to November)Lost Maples, Enchanted Rock, Gruene, LockhartMaple color from mid-October in a good year; cooler hiking
Winter (December to February)Fredericksburg, Lockhart, Castroville, the cavesIndoor museums and barbecue; lifeguards and tubing crowds are gone

September deserves a warning of its own. It still averages 90°F in San Antonio, and the Comal’s lifeguards are off duty after Labor Day, so treat early fall as summer for planning purposes. Our San Antonio events calendar helps you avoid picking your day trip for the one weekend a festival is on in town.

Day Trips With Kids

The shortest drives win with young children: New Braunfels for the river and parks, Guadalupe River State Park for swimming, and the caves for a guaranteed cool hour. Children 12 and under enter state parks free, and Cave Without a Name is free under 6. Enchanted Rock is fine for older kids who can manage a steep scramble, but the dome has little shade. Our guide to San Antonio with kids covers the family days in town.

Accessibility on Day Trips

Accessibility varies widely. Guadalupe River State Park offers an all-terrain wheelchair on request. Cave Without a Name describes its paths as relatively easy concrete and gravel, though any cave involves slopes and some steps, so call ahead. Enchanted Rock’s summit and Lost Maples’ canyon trails are rugged. Town days in Fredericksburg, Gruene and Castroville are usually the most manageable. Call each site before you drive.

Before You Go: A Day-Trip Checklist

  • Reserve dated state park passes. Enchanted Rock, Guadalupe River and Lost Maples all sell day passes online. Check the date before you pay; Enchanted Rock warns that it can’t honor a pass with the wrong date on busy days.
  • Carry water. Enchanted Rock asks visitors to bring their own drinking water because supplies are short in the drought, and summer highs in the region run well into the 90s.
  • Download offline maps. Lost Maples has no cell service, and coverage on Hill Country back roads comes and goes.
  • Read the river rules. Guadalupe River State Park bans Styrofoam and glass along the river, and New Braunfels publishes its own list of what you can and can’t bring on the Comal.
  • Check the day of the week. The Pacific War museum closes on Tuesdays, the Frontier Times Museum opens Monday to Saturday, and small-town restaurants often keep short hours early in the week.
  • Check flow and weather that morning. The Comal closes at high flow, and Enchanted Rock’s Summit Trail can close when it’s wet.
  • Leave early. Parking in Gruene and Fredericksburg fills on weekends, and the popular state parks cap entry.

San Antonio Day Trips FAQ

What is the closest Hill Country town to San Antonio?

Boerne, about 31 miles up I-10 and roughly 39 minutes from the Alamo in free-flowing traffic. Castroville is a touch closer at 26 miles, but it sits west on the edge of the Hill Country rather than in it. Both work as half-day trips, which makes them good choices for a morning when you want to be back downtown by mid-afternoon.

Do I need a reservation for Enchanted Rock?

Reserve if you can. Texas Parks and Wildlife says reserving a day pass online or by phone is the way to guarantee entrance, and the busy season runs September through May. Without one, you risk being turned away on busy days. Entry is $8 for adults and free for children 12 and under, and the gate closes at 8 p.m.

When do the leaves change at Lost Maples?

Usually in late October and November, but the timing varies with weather each year. The park publishes a fall foliage report from mid-October, so check it before you commit to the two-hour drive. October and November are also the months when the park hits capacity every day, which makes an advance day pass essential.

Can you tube the Comal River in the fall?

The river stays open for recreation year-round unless flow reaches 600 cubic feet per second. The catch is that lifeguards at the City Tube Chute stop working after Labor Day, and cooler weather makes the spring-fed water feel colder. Early fall weekdays can be quiet and pleasant; just check the flow and swim with care.

Which day trip is best without a car?

Austin, because Amtrak’s Texas Eagle runs daily between San Antonio and Austin. Every other destination on this page needs a car or a guided tour. Renting for a single day from the airport’s rental facility is usually cheaper and simpler than keeping a car for your whole trip.

Is Fredericksburg worth it for just one day?

Yes, if you plan around the museum. The National Museum of the Pacific War opens at 9 a.m. and deserves three hours, so arrive early, eat lunch on Main Street and leave the wineries for the afternoon with a designated driver. Avoid Tuesdays, when the museum is closed, and expect busy streets on weekends.
