Through donations from our community, we support the maintenance and development of its trails, structures, and open spaces - ensuring a healthy environment for wildlife and continued accessibility for the public.

We are happy to announce that your donations are funding trail work. Working with Redwood Trails Alliance, we completed the road to trail conversion on the Lawndale Trail in 2024. That project reduced erosion and improved safety at the trailhead. We also supported several volunteer trail work days throughout the park. In addition, for the third year in a row we transported hundreds of local fourth graders into the park for a field trip with State Park educators. We are also proud of the help we have given the park staff, especially the fire fighting equipment and an all-terrain wheelchair to give visitors with disabilities the ability to access trails in the park. Our goals for 2024 and 2025 are to ramp up trail work with Redwood Trails Alliance and fund more projects that expand access for everyone in our community. Please join us.
