California Delta Visitor Information

Explore Grizzly Island

Tour expansive wetlands northest of San Francisco, with otters, falcons, and elk.

Making up over 10 percent of California’s remaining natural wetlands, the Suisun (suh-soon) Marsh , 35 miles northeast of San Francisco, is a massive environmental gem—nearly 116,000 acres of rich and diverse habitat for plants and wildlife. Sitting at the confluence of the Sacramento and San Joaquin Rivers, it’s a striking area of low-lying islands and silent, sprawling tidal wetlands, and offers great hiking (trails are level and easy), wildlife viewing, and fishing.

Within the Suisun Marsh is the Grizzly Island complex, an impressive 15,000 acres with 75 miles of roads and trails. To explore Grizzly Island, walk the graveled trails at Peytonia Slough. Wherever you hike, keep a close eye on the trail; you might see river otter footprints or the hoof marks of tule elk. Introduced to the island in the late ’70s, the elk have flourished. Bring binoculars to scan the skies, water, and trees too: the marsh is home to over 220 species of birds. If you’re lucky, you might spot a rare peregrine falcon. Fisherman, take note: Grizzly Island’s waters are home to striped bass, white catfish, white sturgeon, black crappie, and even the occasional largemouth bass. Fishing tip: Bass seem most abundant in early summer, when the normally brackish waters of the marsh are at their freshest.

Camp-California is concerned about the health and safety of our campers and adventurers. While camping and outdoor activities do offer the ability to self-isolate, we are encouraging all California residents and travelers to shelter in place until further notice. We recognize that getting outdoors is what you do best, and we will be here to reacquaint you with nature once we're cleared for adventure again!

 

Most private parks are open with 14-day minimums. If you are a full-time RVer looking to shelter in place, a member of the traveling medical profession, or a utility worker looking for a park please call our office and we can connect you with an appropriate location.
