Sempervirens Fund welcomes you to the new, state-of-the-art entrance to Castle Rock State Park right in Silicon Valley’s backyard.

The Robert C. Kirkwood entrance is state-of-the-art and environmentally friendly. You will find free Wi-Fi, solar panels, potable water, an inviting amphitheater for outdoor education and entertainment, storm water systems that support the San Lorenzo watershed, and more. Robert C. Kirkwood was a local conservationist and active supporter of redwoods and parks in the Santa Cruz Mountains, and we thank him and his family for their support of this special place.

In 1968, Sempervirens Fund helped establish Castle Rock State Park. In addition, Sempervirens Fund has protected more than 35,000 acres of redwood forest in the Santa Cruz Mountains. We work passionately to protect, connect and restore the redwood forests into a vast and vibrant landscape that can support people and wildlife for countless generations to come. Learn more.
