Walking in San Marcos is most enjoyable in the downtown area and along designated trails. However, the city is generally car-dependent, with limited pedestrian infrastructure in many neighborhoods. While walking can be a pleasant way to explore certain areas, the hot Texas summers and lack of shade in some parts may make it less comfortable during peak temperatures. Distances between key locations can also be a factor, as some destinations may be spread out. Overall, walking is best suited for specific areas rather than as a primary mode of transportation across the city.

Pyöräilyä San Marcosissa tuetaan pyöräteillä, yhteiskäytössä olevilla poluilla ja puistopoluilla, joten se on käytännöllinen tapa navigoida tietyillä alueilla. Kaupungissa on yli 100 mailia pyöräilyinfrastruktuuria, joka yhdistää useita kohteita. Jotkin alueet saattavat kuitenkin vaatia varovaisuutta ruuhkan tai rajoitetun pyöräilyreitin takia. Maasto on yleensä hallittavissa, mutta keskeisten sijaintien väliset etäisyydet voivat vaihdella. Pyöräilyn olosuhteisiin vaikuttaa sää, joka voi olla kuuma ja kostea, joten nesteytys ja aurinkosuoja ovat tärkeitä.
