This park features 15 miles of hiking and riding trails through a variety of forested areas including redwoods, mixed evergreens, riparian, ponderosa pine, as well as rare ancient marine deposits called Santa Cruz sandhills. The Zayante Indians once lived in the area, where they found a land with plentiful natural resources.
