Where to See Bison in California
No, California has no native wild bison. The plains bison that roamed North America historically never established a permanent population here. The only bison you can see in California is an introduced herd on Santa Catalina Island, brought to the island in 1924 for a film production and now managed as a controlled population by the Catalina Island Conservancy. A handful of private ranches and zoos also hold bison, but the island herd is the accessible option for most visitors. This guide covers how to plan a realistic California bison trip, starting with the Catalina Island herd and listing backup options.

Santa Catalina Island: where the Catalina bison live
Santa Catalina Island, about 22 miles off the coast of Southern California, hosts the only wild bison you can see in the state. The herd began with a small group brought over in 1924 for a Hollywood film shoot and has been managed by the Catalina Island Conservancy since the 1970s. The population is deliberately kept limited (around 50 to 150 animals) to preserve island habitat and water resources. To see them, you need to visit the island itself, which requires a ferry from the mainland (Avalon or Two Harbors are the main ports). Once on the island, the bison roam in the interior and are not confined to a single viewing area, so spotting them is never guaranteed.
How do you get to Santa Catalina Island to see the herd?
The primary access is via ferry from Long Beach, Dana Point, or San Pedro on the mainland. Catalina Express operates the main passenger ferry service, with trips taking about an hour each way. Once on the island, you can explore on foot, rent a jeep or vehicle if you have appropriate access permits, or join a guided tour. The Catalina Island Conservancy offers educational programs and guided hikes that sometimes include wildlife viewing. The island is also accessible by private boat. Most visitors arrive in Avalon, the main settlement, but bison are in the interior and backcountry areas, so you'll need to venture beyond town.
When is the best season to visit for bison spotting?
Bison on Catalina Island are present year-round, but water availability and weather affect visibility. Spring and early summer (April through June) typically offer the most reliable viewing because animals concentrate around reliable water sources and fresh vegetation is abundant. Autumn (September through November) is also workable. Summer heat can drive the herd to remote interior locations, and winter rains can make backcountry access difficult. Your odds increase if you hire a professional guide who knows current herd locations and movement patterns. Even in ideal seasons, a sighting is not guaranteed, as the island is large and bison numbers are deliberately kept modest.
Are there bison in California outside of Santa Catalina Island?
Yes, a small number. Some private ranches in the Central Valley and Northern California raise bison for conservation or commercial purposes, and a few zoos (including the San Diego Zoo Safari Park) house bison. However, these are not wild herds and access is typically restricted to ranch tours or zoo admission. The Santa Catalina Island herd is the only semi-wild, self-sustaining bison population in California that the general public can attempt to see in a natural setting.
What kind of bison live in California?
The Catalina Island herd consists of plains bison (American bison), the smaller of the two bison subspecies native to North America. They weigh roughly 900 to 1,200 pounds for adults and have the characteristic massive head, hump, and shaggy coat. Plains bison are adapted to grassland and semi-arid environments, which makes them well-suited to the island's Mediterranean climate and chaparral habitat. They are distinct from wood bison, which are larger and historically found in northern forests and marshes.
Can you guarantee seeing bison on these routes?
No. The Catalina Island herd roams freely across the island's interior, and sightings depend on timing, luck, and knowledge of current herd location. Even with a professional guide, bison may be in remote areas or obscured by terrain and vegetation. The conservancy manages the herd for ecological health, not tourism convenience, so the animals' natural behavior and habitat needs take priority. Visiting Santa Catalina Island itself is worthwhile for its native plants, marine habitat, and coastal views, but plan your trip with the understanding that a bison sighting is a bonus, not a guarantee.
What do bison eat on Santa Catalina Island?
Plains bison graze on grasses and eat shrubs, forbs, and other vegetation available on the island. The Catalina Island ecosystem has been shaped by decades of grazing and human land management, so the herd's diet includes both native island plants and some introduced species. Water is a critical resource on the island, and the conservancy monitors water sources and availability to manage herd size and distribution. Unlike their historical Great Plains ancestors, these bison do not migrate seasonally; they are confined to the island's roughly 76 square miles of terrain.
Where is Point Reyes and does it have bison?
Point Reyes National Seashore is a rugged headland north of San Francisco in Marin County. It does not have bison. The trunk guide mentions Point Reyes, likely because some sources incorrectly associate it with California bison, but the park has no bison herds. Point Reyes is home to tule elk, black-tailed deer, mountain lions, and marine wildlife, and it is worth visiting for coastal scenery and hiking, but you will not find bison there.
Are bison protected under California law?
Yes. Bison in California, whether on Santa Catalina Island or in private holdings, are protected under state wildlife laws. The Catalina Island Conservancy manages the island herd under a conservation mandate and works to balance grazing impacts with ecosystem health. Any harvest or population control is done under strict conservation protocols. Private ranches that raise bison must follow California regulations regarding animal welfare and habitat management. No hunting of wild bison is permitted in California.
How many bison are in California?
The Santa Catalina Island herd is the largest wild bison population in California, typically maintained at 50 to 150 animals by the Catalina Island Conservancy. This deliberate cap reflects the island's limited freshwater resources and habitat carrying capacity. Private ranches and zoos in California hold additional bison, but numbers are not centrally tracked. In total, California's bison population is very small and represents only a tiny fraction of the millions of bison that once roamed the Great Plains.
