Welcome to SMGA Volunteer Opportunities

The San Marcos Greenbelt Alliance is an all-volunteer, non-profit organization. Our mission is to create and conserve an interconnected system of parks, natural areas, and trails across San Marcos.

Volunteer opportunities are open to adults and youth, individuals and groups. Many projects take place in local natural areas and you can help out on others from the comfort of your home. We always need a variety of skills and time commitments. We survive on the membership dues, donations, grants, perspiration, brains and brawn of people who understand the value of the natural world. So, find a volunteer opportunity or contact us about a project you're interested in, and let's get to work!
