For those who appreciate native habitats and educational experiences, Ulistac Natural Area stands out as Santa Clara’s only dedicated natural open space. Praised by Bay Nature and the Santa Clara Valley Audubon Society, this 40-acre preserve is a living classroom of restored grasslands, wetlands, and oak woodlands. Volunteers and local groups have shaped the park into a haven for birdwatchers and botany enthusiasts, with interpretive signs and regular restoration events. Its winding trails offer peaceful walks away from the city bustle while celebrating the area’s indigenous Ohlone heritage.
