Great Valley Grasslands State Park

UPDATE (May 22, 2020) - As California State Parks begins working with locals on a phased and regionally-driven approach to increase access to state park units where compliance with state and local public health ordinances can be achieved, it is important for visitors to continue to practice physical distancing and avoid congregating with people outside their immediate household. Everyone has the responsibility to mitigate the spread of COVID-19.

Here are some guidelines for people visiting Great Valley Grasslands State Park:

What is open now?

  • The park is open from 6 a.m. to 8 p.m.
  • Limited paved day-use parking only
  • Trails
  • River access
  • Vessel launch

What is currently closed at this park and throughout the State Park System?


Statewide:
  • Campgrounds.
  • High public-use indoor facilities, including museums and visitor centers.
  • Special events and public gatherings continue to be canceled until further notice.

Are there any new visitor guidelines?

Yes, please see below:
  • Stay Local: Stay close to home. Walk or bike into the park. Parking is very limited. Do not take road trips to parks and beaches or to neighboring states.
  • Stay Active: Keep walking, jogging, hiking and biking. Watch for one-way trails.
  • Stay Safer at 6 Feet: Maintain a physical distance of 6 feet or more. Gatherings, picnics and parties are not allowed. Visitors will be asked to leave if there are too many people at the park, beach or on trails to allow for the required physical distance.
  • Stay Clean: Be prepared. Bring soap/sanitizer and pack out all trash.
  • Stay Covered: The state now requires you to wear a face covering in most indoor settings and public outdoor spaces when you cannot maintain physical distancing of six feet or more from people outside of your immediate household. For details, please visit CDPH’s guidance here. Visitors should also abide by their local county health orders.

The park preserves one of few intact examples of native grasslands on the floor of the Central Valley. The park is part of the larger Grasslands Ecological Area (GEA) of federal, state and private lands all managed for wildlife values. The GEA represents the largest remaining contiguous block of wetlands in California. Several rare and endangered plant and animal species inhabit the park, including alkali sacaton, a native bunch grass, and the Delta button celery (Eryngium racemosum) a state listed endangered species found in the flood plain of the San Joaquin River. Biologists have also reported the California Tiger Salamander and endangered vernal pool fairy shrimp and tadpole shrimp. Springtime wildflower displays, fishing and wildlife watching attract visitors to this undeveloped park, which also encompasses the former Fremont Ford State Recreation Area.
