New Forest Health Initiative underway at Castle Rock State Park
A plan to reduce wildfire danger and preserve forest biodiversity at Castle Rock State Park is underway, California State Parks announced earlier this month.
Black oaks are a rare and essential part of the Santa Cruz Mountains ecosystem that require active management to continue thriving. This initiative will protect black oak woodlands, and many other fire-dependent plant communities as well as the animals that depend on them. This is the first step towards restoring a historically biodiverse landscape that was carefully tended by native Ohlone people prior to European colonization.

The 5.6-mile Saratoga Gap and Ridge Trail Loop leads to Goat Rock, Castle Rock Falls, Russell Point Overlook, and the Castle Rock Trail Camp. Goat Rock Overlook provides panoramic views of the San Lorenzo Valley and the Pacific Ocean. The moderately difficult Ridge Trail is a potential place to see the endangered peregrine falcon. The Saratoga Toll Road, a historic logging road and stagecoach line from 1871, is now a well-shaded and graded hike offering some scenic viewpoints.

Judge Joseph Welch of Santa Clara Valley purchased a 60-acre parcel on Castle Rock Ridge in 1908, when logging was still ravaging the hillsides. He established a precedent by opening his land for the public to enjoy its scenic vistas and rugged landscapes. With Welch’s determination, Castle Rock soon became a popular tourist destination.
Dr. Russell Varian, a pioneer of X-ray and radar technology, spent much of his youth exploring and hiking the canyons near Castle Rock. Varian was the first to measure Earth’s magnetic field, using some sites in today’s park. In 1959, he secured an option to purchase this land and planned to donate it to California State Parks. Varian died before completing the purchase.
The Sierra Club and Sempervirens Fund later donated the land in his memory. Castle Rock was designated a State Park in July 1968. In 2011, Castle Rock was one of 70 State Parks set for closure by Gov. Jerry Brown. A partnership of Portola-Castle Rock Foundation, Save the Redwoods League, Peninsula Open Space Trust and Sempervirens Fund donated $250,000 to protect the park from closure.
