OSA Nature Counts! with iNaturalist NEW!
Secret Spring
Now is your chance to welcome spring on the OSA’s pristine Coyote Valley property. You are cordially invited to be among the first in decades to hike the area. We’re hosting three Secret Spring “sneak previews” of this biologically diverse, 348-acre property. Coyote Valley is host to wildlife and rare plants such as the Bay Checkerspot butterfly and Leptosiphon ambiguous, a pink wildflower that grows only in serpentine soils. The land isn’t yet open to the public, but we can’t wait to show it off. Secret Spring hikes take place on March 15, April 21, and May 5.
See activities calendar.
Coyote Spring
Just one month per year, OSA offers special hikes on the specactular Coyote Ridge which is blanketed in color from special-status plants like the Santa Clara Valley dudleya, most beautiful jewel flower, and Tiburon paintbrush. Orange poppies, yellow tidy tips and the goldfields make for a visual paradise.
First-come, first-serve for these limited hikes. Reseve your spot now.
