Mount Madonna supports a highly diverse landscape with redwood forests, oak woodland, dense chaparral and grassy meadows.
Banana slugs when the ground is wet, red-tailed hawks and black-tailed deer.
The park was once the home of cattle baron Henry Miller; a one-mile self-guided nature trail takes you around the ruins of his summer home. There is also an archery range and multiple camping options, as well as an amphitheater that features nature-led slide shows every Saturday evening from Memorial Day through Labor Day. The famous white deer – the first of which were donated by William Randal Hearst over 85 years ago – are a popular attraction for families and are kept near the visitor center.
