Bidwell Park, Municipal park in Chico, California.

Bidwell Park is a municipal park in Chico, California, stretching about 11 miles (18 km) along Big Chico Creek from Bidwell Mansion to the foothills of the southern Cascades. It covers 3,670 acres (1,490 ha), divided by Manzanita Avenue into a flat, tree-shaded Lower Park and a steeper Upper Park with volcanic rocks and the Chico Formation sandstone.

Annie Bidwell donated about 2,500 acres (1,000 hectares) to Chico on July 10, 1905, with roughly 49 hectares added after her death in 1911. The park grew through later purchases, including Cedar Grove in 1922 and 1,200 acres south of Big Chico Creek in 1995. It lies on the traditional territory of the Mechoopda, a Maidu subgroup.

Bidwell Park lies on the traditional territory of the Mechoopda, a Maidu subgroup whose roughly 23 permanent settlements stretched from present-day Nord to Durham. The Hooker Oak Recreation Area is named for a valley oak that stood by Manzanita Avenue until a 1977 storm felled it; inspection showed it was two trees grown together. Above the Sycamore Pool fish ladder, locals feed sucker fish from the bridge.

The park offers multiple activities including hiking, mountain biking, swimming at Sycamore Pool, disc golf, and horseback riding on marked trails. The best time to visit is late spring or fall when weather is mild and paths are most accessible.

The pale driftwood log lying on dark basalt boulders in Upper Park is a clue to the rock beneath: Lovejoy Basalt, one of the formations the park's steep slopes expose. The log's smooth, bleached surface and broken branch stubs show how long water and sun have worked on it.
