Rancho del Oso Unit
RDO entry


Rancho del Oso is the ocean end of Big Basin Redwoods State Park. Prior to the CZU Lightning Complex Fires, the park offered a variety of recreational opportunities, including hiking, biking and horseback riding. The majority of these trails and activities remain inaccessible due to fire damage.

Waddell Beach, located across Highway 1 from the park entrance, is known worldwide as one of the spots for windsurfing and kite surfing. The steady strong northwest winds and good surf provide ideal conditions for this demanding sport.

The new Rancho del Oso Welcome Center, a gateway to the western coastal side of Big Basin Redwoods State Park, is now open. The new welcome center facility and adjacent public campground will greet visitors to California’s oldest state park and largest expanse of old-growth coast redwoods south of San Francisco. The campground includes five campsites that can be reserved and one non-reserved bike-in site.

Things to do

Welcome Center

The new 684-square-foot Rancho del Oso Welcome Center, with its 480-square-foot observation deck, supports outdoor group programs and general recreational opportunities for the park. The center features interactive and virtual interpretive exhibits, hand-painted murals of the local coastal ecosystem and ocean views.


The Horse Camp at Rancho Del Oso Unit on the coast side of Big Basin has been rehabilitated and is open for interim walk-in and bike-in, non-equestrian camping. Reservations are required.

The campground will be reinstated as a Horse Camp once equestrian trails have been restored.


Take a stroll on the Marsh Trail at Rancho del Oso, the coastal side of Big Basin Redwoods State Park. This short hike (less than a mile!) meanders through the Theodore J. Hoover Nature Preserve. Birdwatch, be on the lookout for lizards and view Waddell Creek. (The seasonal bridge will be removed mid-October.)

Windsurfing and Kite Surfing

Launching from the tops of incoming waves the best windsurfers can complete full loops and continue on their way. With the strong winds and occasionally heavy surf, Waddell Beach is not recommended for novice wind surfers. Regular surfers and boogie boarders also find it an ideal spot to pursue their activities.

Bird Watching and Wildlife Viewing

The Theodore J. Hoover Natural Preserve is great for birders. The Marsh Trail is teeming with life. Rabbits are frequently seen scurrying off the trail, while dragonflies swoop over the water, and birds flit among the willows growing near the creek. Due to the abundance of water, flowering plants have an especially long season here.

Visitor Center

The Nature and History Center features interactive exhibits sharing the wonders and diversity of the Waddell Valley. Turn right before the Waddell Beach parking lot, you’ll see a sign marked “Rancho del Oso Nature and History Center.” The Center is open 12 p.m. to 4 p.m. Saturdays and Sundays.

There are currently five walk-in campsites by reservation and one shared non-reserved bike-in site available temporarily at the Rancho del Oso (RDO) Horse Camp. Trails from RDO are closed and were severely damaged in the CZU Lightning Complex Fire in 2020. Trail access north from RDO into Big Basin along the Skyline to the Sea Trail is not expected to be restored for several years making equestrian camping at the site impractical during this interim period. Rancho del Oso Horse Camp is operating as an interim walk-in and bike-in campground until trail access from Rancho del Oso is reopened for equestrian use, at which point the horse camp will be reinstated for equestrian camping.

Rancho del Oso, a unit of Big Basin State Park, is in the unceded homelands of the Awaswas-speaking Ohlone Tribe known as the Cotoni and Quiroste, who stewarded these lands since time immemorial. Centuries of colonial violence led to the removal and displacement of the Cotoni and Quiroste. Today, their descendants continue their stewardship and presence here, in partnership with State Parks.

Rancho del Oso is a site rich in cultural and natural history. The area was frequented by Native Americans (most likely the Awaswas clan of Ohlone Costanoan), who managed the land in order to benefit from the bountiful landscape and encourage the proliferation of game.

In 1912, Theodore Hoover (Dean of Engineering at Stanford and brother of President Herbert Hoover) bought a majority of the Waddell Valley from more than a dozen small landowners. Hoover built the “Brown House” in 1913 as a family vacation house (a role it still serves) and named his holdings Rancho del Oso. In 1925 he built a large Spanish-style residence, the “Casa,” for his family across the creek from the Brown House. Although the Casa was destroyed by fire in 1959, several of Theodore Hoover’s heirs still have residences at Rancho del Oso.

California State Parks acquired approximately two-thirds of the original Rancho del Oso land including Waddell Beach, from Hoover’s daughters in 1977. This enabled the completion of the Skyline-to-the-Sea Trail.

In 1985 Hulda Hoover McLean sold her personal residence and its 40-acre lot to the Sempervirens Fund, intent on creating a place to share the wonders of the natural world with others. After some minor renovations, it was passed on to California State Parks for use as the Rancho del Oso Nature and History Center. She was very active in organizing the Waddell Creek Association, which helps support the volunteer and educational programs at Rancho del Oso, and served on its board of directors well into her 90s. She died in 2006 at the age of 100.


  • Dogs are not allowed in any portion of Rancho del Oso.
