TrailsTrail sign

There are two developed trails within the park. The North Trail, a one-mile round-trip, starts near the museum. It traverses the ridge surrounding the meadow, passes by the old farm site, crosses the creek, and continues to the reconstructed Miwok village site before returning to the museum by way of the roundhouse and grinding rock.

The half-mile long South Trail starts near the roundhouse and has an accompanying trail guide that identifies some of the plants that were used by the Miwok.  A trail guide is available for 50 cents and is located at the start of the South Trail near the round house; deposit money into the brown metal box with the guides. 



The park is small, but offers many opportunities to observe wildlife. The mixture of oak woodlands and mixed pine forest provides a wide variety of habitats.

Birdlife varies depending on the season, but many species are seen year round, including turkey vultures, scrub and Steller's jays, California quail, acorn and hairy woodpeckers, northern flickers, hermit thrushes, wild turkeys (non-native), and California thrashers. In summer, the bright colors of the western tanager, northern oriole, calliope and Anna's hummingbirds can be seen in the woods around the meadow. A bird list is available at the museum.

Animal life in and around the park includes deer, fox, gray and California ground squirrels, black-tailed jackrabbits, bobcats, bats, and occasionally a mountain lion or black bear. The legendary coyote - the trickster of Miwok stories - can be heard singing on quiet summer nights.
