Leave Richmond around 1:00 PM for the roughly 3½–4-hour drive to San Marcos, taking US-59 toward Houston and then I-10 west before connecting toward San Antonio and San Marcos. Expect possible Houston-area traffic, so build in one fuel and food stop rather than trying to rush; keep water in the car, especially in September. On arrival, check in and use your hotel parking if available, or choose a downtown public lot or street space and leave the car there for the evening—Downtown San Marcos is compact and easiest on foot.
After settling in, spend about 30 minutes at the Hays County Historic Courthouse, an impressive limestone landmark on the central square. Then wander The Square for roughly 45 minutes, taking in local storefronts, murals, and the relaxed college-town atmosphere. Most shops begin closing in the early evening, but the streets and public areas remain pleasant for a stroll; September temperatures can still be warm, so carry water and save the shadiest side of the square for walking.
Have dinner at Palmer’s Restaurant Bar & Courtyard, a good first-night choice with a relaxed setting and courtyard seating when available. Plan on about $20–$35 per person before drinks and allow 1½ hours; reservations are useful on a Saturday, though arriving early can help. Afterward, walk down to the San Marcos River Walk for an easy 45-minute sunset stroll along the riverfront. The paths are generally straightforward, but wear comfortable shoes and bring a light layer for the evening; return to your hotel afterward so you are rested for tomorrow’s outlet shopping.
Start at San Marcos Premium Outlets when it opens, typically around 10:00 AM; verify September hours before leaving, since individual stores and holiday weekends can vary. Give yourself four to five hours—the center is sprawling, with indoor and outdoor sections—so wear comfortable shoes and park near the section where you plan to begin. This is the time to compare prices carefully: popular brands can have additional in-store promotions, while the best selection is usually available earlier in the day. Bring a reusable tote and plan a short break rather than trying to cover every store.
For a practical reset, drive a few minutes to H-E-B plus! San Marcos and pick up sandwiches, fruit, drinks, or prepared foods for roughly $10–$20 per person. It is a good choice when you want to keep shopping momentum without committing to a long restaurant meal; allow about 45 minutes, including checkout. Keep anything perishable in an insulated bag if you are continuing to explore, and check the store’s current hours before going.
Head south to Rio Vista Park for an easy hour beside the San Marcos River. Follow the paved paths around the water and small waterfalls, but be cautious on wet rocks and expect warmer conditions in September; late afternoon is much more comfortable than midday. From the park, downtown is only a short drive, and street parking can fill before dinner, so arrive early or use a nearby public lot. Have dinner at Silo Restaurant, where contemporary American dishes generally run $25–$45 per person; reservations are sensible, particularly on a Sunday evening. Finish at Cheatham Street Warehouse, a landmark live-music venue in downtown San Marcos. Check the evening’s schedule and age restrictions in advance, and bring cash or a card for the cover and drinks; arrive 30–45 minutes before the listed set if you want a good view.
Start early at Texas State Tubes for the trip’s river-cruise-style experience on the San Marcos River. Aim for a morning check-in, since the float usually takes about 2–3 hours and late-morning temperatures can become very hot in September. Reserve ahead and confirm seasonal operating dates, shuttle details, water levels, and the required arrival time; bring water shoes, sunscreen, and a dry change of clothes, and leave valuables locked at your lodging rather than in the car. After the float, allow time to change and use the restroom before driving roughly 35–40 minutes northwest to Blue Hole Regional Park in Wimberley.
At Blue Hole Regional Park, keep the stop relaxed: walk the riverside paths, photograph the cypress-lined water, and enjoy the Hill Country scenery for about an hour. Swimming access and reservations can be seasonal, so treat this as a scenic walk unless you have confirmed entry in advance. Continue a few minutes into central Wimberley for lunch at CreekHouse Kitchen & Bar on Wimberley Square; budget approximately $20–$35 per person, and check Sunday hours and seating before setting out, since small-town restaurant schedules can change.
After lunch, spend about an hour around the Wimberley Market Days area, browsing local galleries, craft shops, and boutiques around Wimberley Square. Market Days themselves are generally held on the first Saturday of the month, so on this Monday the square is best treated as a pleasant shopping area rather than a full market—some businesses may open later or close on Mondays. Leave around 2:30–3:00 PM for Richmond, taking local roads toward US-290 and then I-10 east; the drive is roughly 3–3½ hours in light traffic, but allow extra time around Austin, Houston, and the I-10/Grand Parkway approaches. Stop for fuel before reaching the busier Houston corridor and expect an early-evening arrival in Richmond.
