For the past 24 years Green Spaces Alliance has been connecting people with nature through education, stewardship, and the cultivation of community. Join us as we bring the San Antonio community together to enjoy nature along the famous riverwalk and engage in a wide range of outdoor activities at Mission Park.

We're bringing you something new while still keeping a classic that you love, Run the River. Start your morning off with our widely popular “Run the River” 5k walk/run along with San Antonio Riverwalk before joining us for a day filled out outdoor fun.With a little something for everyone, the Green Spaces Alliance Nature Festival is sure to connect the community with the outdoors in a fun and exciting way.
