9 Things to Do in San Marcos Besides Shopping

Most people come to San Marcos for the outlets. Fair enough — two massive open-air malls within walking distance of the hotels at I-35 exit 200 is a real draw, and we'd never talk you out of a shopping day. But if you've already done the outlets, or you've got a second day, or you're the person in the group who'd rather be literally anywhere else while someone shops, this list is for you.

San Marcos is a spring-fed-river town with a state university, a century-old show cave, a hangar full of warbirds, and enough water-based activity to fill a week. Almost none of it shows up in the outlet-mall search results, which is the problem this post exists to fix.

One thing to know before you start planning: everything on this list except the outlets needs a car. The malls are a six-minute walk from our hotel; the river, the cave, the campus — all about ten minutes by car. That's not far, but it's not walkable.

1. Swim in the San Marcos River

The San Marcos River is spring-fed, which means it holds roughly 72 degrees year-round, it's clear enough to see the bottom, and it doesn't depend on rainfall the way most Texas rivers do. In summer that's refreshing. In October it's still swimmable. The river is the single best reason to spend a day in San Marcos that has nothing to do with shopping.

Swimming and snorkelling are the simplest ways in — no reservation, no outfitter, just get to the water. The river is about ten minutes from the hotel by car. For the full breakdown on water access and what's nearby, check our things to do page.

2. Take a glass-bottom boat at the Meadows Center

The Meadows Center for Water and the Environment sits on the former Aquarena Springs site, now owned and run by Texas State University. The draw is the glass-bottom boat tour over the spring vents — you float over spots where water literally pushes up through the lake bed, and the clarity is startling. Visitors report seeing fish, turtles, and gar through the glass, and the student guides know the ecology cold.

There's also an indoor aquatic center with local fish and salamanders, which is a solid with-kids stop. The surrounding grounds are lush and worth a short walk after the tour.

Two practical notes. The centre closes at 5 PM but the last boat tour departs at 4:30 — if you show up at 4:45, you've missed it. And parking costs $3 on weekdays; at least one reviewer noted that weekends avoid the fee, though we'd suggest confirming that at the gate.

3. Explore Wonder World Cave and Park

Wonder World is the first show cave opened to the public in Texas, and it's been running tours for over 105 years. That's a real track record. The cave itself is genuinely unusual: it was formed by the Balcones Fault Line — an earthquake-formed cave, not a water-carved one — which makes it geologically distinct from the limestone caverns you'll find elsewhere in the Hill Country.

The park adds an observation tower and a small wildlife park around the cave.

We'll be honest, because the 3.9 TripAdvisor rating (from 234 reviews) already hints at it: the above-ground attractions feel dated in places, and the overall experience is priced more like a theme park than you might expect. The cave itself, though, is the real draw and worth the trip if you have any interest in geology. Go for the cave. Treat everything else as a bonus.

4. See a D-Day aircraft at the Commemorative Air Force hangar

The Central Texas Wing of the Commemorative Air Force operates out of a hangar at San Marcos Regional Airport, and it houses something genuinely rare: the C-47 "That's All, Brother," the aircraft that led the entire D-Day paratrooper drop on June 6, 1944. The plane was rescued from a boneyard, restored to flying condition, and now lives here.

It's not alone. The wing maintains and restores seven aircraft total, including a very rare flying P-39 Bell Airacobra. The work is done by volunteers, and they're the ones who walk you through the hangar and tell the stories. That personal, unhurried quality is probably why it carries a 4.8 on TripAdvisor — the highest rating of any attraction in San Marcos, even with a smaller review count (66).

This is the kind of place you stumble on and tell people about afterward. If you have any interest in aviation or history, don't skip it.

5. Browse the Wittliff Collections at Texas State

Free. Quiet. Rarely busy. On the top floor of the Texas State University library, the Wittliff Collections are devoted to the creative legacy of the American Southwest. The highlights include Lonesome Dove manuscripts and related material, a deep collection of Southwestern and Mexican photography, and Texas music archives.

It's the kind of space where you wander for an hour and leave knowing something you didn't before. It also happens to be the ideal rainy-afternoon option — air-conditioned, no cost, no reservation, and genuinely interesting rather than a fallback. If you've spent a day outside and want something slower, this is it.

6. Tube the San Marcos River

Swimming is one thing. Tubing is a different experience — you're on the river for an extended stretch, floating through town, and it's the activity San Marcos is probably most associated with after shopping.

Two outfitters worth knowing:

Lions Club Tube Rental — (512) 396-5466, tubesanmarcos.com. Based at City Park with tube rental and shuttle service. This is a nonprofit operation that funds local community causes, which is a nice reason to choose them. TripAdvisor 4.4.

Texas State Tubes — (512) 638-7165, texasstatetubes.com. Full trips with bus shuttle included, running seven days a week roughly May through the end of August. TripAdvisor 4.6 from 140 reviews.

One honest note: at least one reviewer warned that the river route was more physically demanding than they expected — paddling, obstacles, not the leisurely float the word "tubing" implies. That reviewer specifically said they wouldn't recommend it for older adults or large groups. Take that into account.

7. Kayak or paddleboard the river

If tubing sounds too passive — or too crowded — kayaking and stand-up paddleboarding give you more control and often more river to yourself.

Paddle SMTX — (512) 400-6259, paddlesmtx.com. Rentals and guided tours from City Park, open year-round. Their 4.9 TripAdvisor rating from 741 reviews is remarkable and consistent.

Get Up And Go Kayaking runs clear-kayak tours — transparent hulls so you can see the river bottom beneath you — and is the only watercraft operator open year-round. Their signature trips are clear-kayak day and sunset tours. They carry a 5.0 rating from 269 reviews, which at that volume is essentially unheard of. We couldn't verify a phone number for them, so head to their website to book.

The clear-kayak tours in particular are one of the more distinctive outdoor experiences you'll find anywhere in central Texas. If the weather's cooperating, this is a strong candidate for the best thing on this list.

8. Catch a game at UFCU Stadium

Texas State University's football program plays at UFCU Stadium, about ten minutes north of the hotel. The Bobcats are FBS, and the stadium has grown considerably in recent years — good sight lines, manageable parking compared with bigger programs, and a college-game atmosphere without the logistical headache of Austin or San Antonio.

The catch: home-game weekends fill every hotel in town. If you're planning a trip that happens to land on a fall Saturday, check the schedule and book well ahead. For more details on game-day logistics and what else to do on a football weekend, see our things to do page.

9. Try the farmhouse ales at Roughhouse Brewing

Roughhouse Brewing sits on five acres of the Pasternak family ranch just south of Wimberley, and the focus is farmhouse ales brewed by a family operation. It's the kind of brewery where the setting is half the point — Hill Country land, open air, no corporate polish.

If you're making a brewery run of it, Middleton Brewing (4.4 on TripAdvisor, 41 reviews) is nearby and worth a stop on the same drive. For more on where to eat and drink in the area, our dining page covers the closer-in options.

Honorable mentions: day trips from San Marcos

These didn't make the main list because they're out of town, but San Marcos sits right on I-35 between Austin and San Antonio, which puts a remarkable number of day trips within easy reach:

• Gruene historic district and Gruene Hall — about 15 miles. Texas's oldest dance hall, and the town around it is worth a wander.
• Blue Hole Regional Park, Wimberley — about 13 miles. A swimming hole in a cypress-lined creek.
• Schlitterbahn, New Braunfels — about 17 miles. The water park that's been a Texas family staple for decades.
• Natural Bridge Caverns — about 28 miles. A more polished cave experience if Wonder World left you curious.
• Austin — about 30 miles. Barton Springs Pool, the Texas Capitol, the Congress Bridge bats at dusk.
• San Antonio — about 45 miles. The River Walk, the Alamo, and everything that comes with a much bigger city.

Any of these works as a half-day or full-day trip from a San Marcos base. You're squarely between the two big cities, which is the geographic advantage nobody thinks about when they book here for the outlets.

How we chose

This isn't a scraped list of every attraction within a certain radius. We started with the places that show up consistently in local recommendations and traveler reviews, then filtered for things that are genuinely distinct — not just "another park" or "another restaurant." Each item has a real TripAdvisor presence and a rating we're comfortable standing behind (with honest caveats where the rating tells a mixed story, like Wonder World). We also weighted variety: water, history, nature, sports, beer. A list of nine river activities would be accurate but not useful. And we confirmed outfitter details — phone numbers, websites, operating seasons — rather than relying on directory listings. For a broader and more interactive version of the nearby options, including distances and categories, see our things to do page.

A note on logistics

San Marcos is a small town stretched along I-35, and the outlet district at exit 200 — where our hotel sits — is on the highway, not downtown. The Premium Outlets are a six-minute walk; Tanger about seven. That walkability is genuine and unusual for a highway hotel. But everything on this list is a drive. The river, the Meadows Center, the cave, the stadium, the breweries — all roughly ten to twenty minutes by car. If you're coming for the outlets and adding a second day, you'll want a car for that second day.

The upside is that you come back to free parking, a pool and fitness center, and a free hot breakfast the next morning. That's the practical case for basing here: the shopping is on foot, the rest of the town is a short drive, and the hotel handles the basics well enough that you don't need to think about them.

Planning a trip beyond the outlets? Check availability and give yourself that second day.
