Earth Day isn't just one day in the Bay Area — it's the entire month of April, and the Bay goes all out. From free festivals at Yerba Buena Gardens in San Francisco to creek cleanups, nature hikes in, volunteer days , and family celebrations, there's something happening in nearly every corner of the Bay Area. Whether you're looking for a low-key afternoon with the kids or want to actually roll up your sleeves and give back, this list has you covered. I've rounded up a few events across all regions so you can find what's closest to you, and maybe even make a whole day of it.
