The City of San Marcos has more than 1,000 acres of natural areas. The San Marcos Greenbelt Alliance built and maintains 33 different trails with 22 miles available for mountain biking, hiking, running and enjoying nature. While the natural areas serve many different purposes including flood mitigation and water quality, they should also be considered outdoor classrooms.
