Big Basin Redwoods State Park is the oldest state park in California. It was acquired in 1902. The park has miles of trails, which serve hikers and equestrians, link Big Basin to Castle Rock State Park and the eastern reaches of the Santa Cruz range.

The Skyline to the Sea Trail threads its way through the park along Waddell Creek to the beach and adjacent Theodore J. Hoover Natural Preserve, a freshwater marsh. The park has a surprising number of waterfalls, a wide variety of environments (from lush canyon bottoms to sparse chaparral-covered slopes, many animals (deer, raccoons, bobcat) and lots of bird life (including Steller’s jays, egrets, herons and acorn woodpeckers.)

The story begins in 1889 at Henry Cowell Redwoods State Park when painter/photographer Andrew P. Hill was hired to take pictures of redwoods in Welch’s Grove (now Henry Cowell Redwoods State Park). But Welch would not let him take pictures of his grove so Hill traveled to Big Basin area instead. He was so inspired by the grandeur of the redwoods, and so alarmed that all these giants were being cut down, that he vowed that the magnificent trees should be saved for generations to enjoy.

Hill and friends, such as journalist Josephine McCracken, attracted wealthy and influential people who formed the Sempervirens Club. These visionaries raised funds and convinced legislators to purchase Big Basin. Thus began the preservation movement and in 1902 the establishment of California’s first State Park.

Since that time, public and private partnerships have added to the park with its original 3,800 acres increasing over the years to more than 18,000 acres. Behind these efforts lie the passionate stories of visionaries, visitors and workers and the history of this preservation movement.
