Leave Richmond around 6:30 AM for the roughly two-hour drive to San Marcos. Take US-59 N toward Houston, then I-10 W and SH-130 N; SH-130 is generally the smoother choice around Austin, though tolls apply. Start with a full tank and bring a toll tag or expect a mailed toll bill. On arrival, head straight to San Marcos Premium Outlets and park near the section of stores you want to browse—this sprawling center is much easier to navigate before the late-morning crowds.
Allow three to four hours at San Marcos Premium Outlets, one of the largest outlet centers in the country. Sunday hours commonly begin around 10:00 AM, but check the current store directory before leaving, since individual retailers and seasonal promotions vary. Wear comfortable shoes, bring sunscreen and water, and take a photo of your parking area; the center is large and divided into multiple sections. Grab coffee or a quick breakfast on-site, then meet for lunch at Saltgrass Steak House near the outlets, budgeting about $20–35 per person for a Texas-style meal. A reservation is useful if you are traveling with a group.
After lunch, drive about 15 minutes to the San Marcos River and confirm that the guided paddleboat or river-cruise-style sightseeing option is operating before counting on it—services are seasonal, and reservations are strongly recommended. If no cruise is running, use the reserved river outing or scenic tubing arrangement you made in advance; the water stays cool even on warm days, so a towel, dry change of clothes, and secure footwear are worthwhile. Leave roughly two hours for the water activity, then spend an hour strolling Sewell Park and Downtown San Marcos along the River District. The park is especially pleasant in the late afternoon, with shaded riverbanks and easy paths; keep an eye on the time so you can return to Richmond before evening traffic builds.
Aim to depart San Marcos between 4:30 and 5:00 PM via SH-123 S to I-35 S, then I-10 E and US-59 S toward Richmond. Expect approximately two to two and a half hours, depending on Austin-area and Houston-area traffic. A practical rest or dinner stop is around Katy along I-10; otherwise, continue past the busiest Houston interchange before stopping. Keep extra water in the car and allow additional time if the river activity runs late or Sunday traffic is heavier than expected.
