About this park

Merced National Wildlife Refuge

Merced National Wildlife Refuge is a 10,258-acre wildlife sanctuary located in the Central Valley of California. The refuge protects wetlands, grasslands, and riparian habitats, making it home to an impressive array of birds and other animals.

One of the main reasons to visit the Merced National Wildlife Refuge is for birdwatching. The refuge is a critical stop for migratory birds along the Pacific Flyway, with over 300 species of birds recorded here. Visitors have the opportunity to see large flocks of snow geese, sandhill cranes, and other waterfowl during the winter months.

Other points of interest at the refuge include the auto tour route, which takes visitors through the wetlands and offers opportunities to see wildlife up close. The Visitor Center also provides educational exhibits and programs, and there are multiple hiking trails to explore the diverse habitats.

Interesting facts about the area include that the refuge was established in 1951 to provide habitat for waterfowl and other migratory birds, and has since grown to include other endangered and threatened species like the Swainson's Hawk and the San Joaquin Kit Fox. The refuge also has a partnership with the nearby UC Merced for research and conservation efforts.

The best time of year to visit the Merced National Wildlife Refuge is during the fall and winter months, when the migratory birds are present in large numbers. However, spring and summer also offer opportunities to see resident birds and other wildlife. It is important to note that certain areas of the refuge may be closed during certain times of the year to protect nesting and breeding species.

Land designation

Park & land designation reference

A quick legend for the federal and state land categories Snoflo tracks. Each designation comes with different rules around access, recreation, and resource extraction.

National Park
Large protected natural areas managed by the federal government to preserve significant landscapes, ecosystems, and cultural resources; recreation is allowed but conservation is the priority.
State Park
Public natural or recreational areas managed by a state government, typically smaller than national parks and focused on regional natural features, recreation, and education.
Local Park
Community-level parks managed by cities or counties, emphasizing recreation, playgrounds, sports, and green space close to populated areas.
Wilderness Area
The highest level of land protection in the U.S.; designated areas where nature is left essentially untouched, with no roads, structures, or motorized motorized access permitted.
National Recreation Area
Areas set aside primarily for outdoor recreation (boating, hiking, fishing, often around reservoirs, rivers, or scenic landscapes); may allow more development.
National Conservation Area (BLM)
BLM-managed areas with special ecological, cultural, or scientific value; more protection than typical BLM land but less strict than Wilderness Areas.
State Forest
State-managed forests focused on habitat, watershed, recreation, and sustainable timber harvest.
Bureau of Land Management (BLM) Land
Vast federal lands managed for mixed use -- recreation, grazing, mining, conservation -- with fewer restrictions than national parks or forests.

Responsible recreation & Leave No Trace

Know before you go
Check the operator's site for hours, permit requirements, seasonal closures, and fire restrictions before heading out.
Stay on trail
Stick to marked paths to protect vegetation, prevent erosion, and avoid disturbing wildlife habitat.
Respect wildlife
Observe from a distance, never feed wildlife, and store food securely if camping is permitted on-site.
Pack it in, pack it out
Carry out all trash, food scraps, and gear. Many parks have limited or no trash service.
Leave what you find
Don't take rocks, plants, or artifacts. They make the park what it is for the next visitor.
