About
San Diego River Days were initially conceived as a way to highlight the year-round work done by local groups to improve the health of the San Diego River, educate people about our River, and engage community members in River-friendly recreation or action. Many amazing organizations, agencies, and businesses offer opportunities for community members to get involved all along the River, from the mountains to the ocean. For San Diego River Days each year, the different groups plan a series of events to give the community a sampling of their exciting work.
This is the 22nd year of the annual San Diego River Days celebration. The San Diego River Park Foundation and partners are offering a variety of fun and free activities from May 10th through May 18th that engage over a thousand participants of all ages! These free activities are designed to be approachable and fun. By trying out something new, attendees are able to get to know a local group, explore a new place, connect with nature, and learn something new about their community.

About the San Diego River Park Foundation
In 2000, the largest sewer spill in California’s history dumped 34 million gallons of untreated sewage into the San Diego River. This spill ran for almost a week, while few people noticed or cared. Out of this tragedy, a group of concerned citizens formed the San Diego River Park Foundation on July 18, 2001. Since this tragedy, the San Diego River Park Foundation has worked with the community to change San Diego’s relationship to its namesake waterway.
We are working to create a better future for our San Diego River by advocating for the creation of a 52-mile river-long park and trail system, cleaning up trash from the river, educating youth about nature, restoring native habitat, conserving land for wildlife, researching and monitoring the riparian environment, and engaging the community in volunteerism and advocacy. We remain a local, grassroots non-profit organization and we rely on donations, support from the community, and public and private grants for our work creating the San Diego River Park, connecting people to the River, and conserving local resources.
