The 26-facility county parks system includes the Irvine Ranch Open Space, comprising Limestone Canyon, Weir Canyon and Fremont Canyon nature preserves, as well as Black Star Canyon Wilderness Park.
Description
-SCHEDULED ACTIVITIES ONLY-
This spectacular and lush canyon includes thick oak woodlands, streamside habitats, year-round springs and an iconic geological formation called "the Sinks,” often compared to a mini-Grand Canyon. A rich diversity of plants and animals as well as an unusual variety of natural habitats make Limestone a true favorite among hikers, mountain bikers and naturalists of all types. Registration is required for docent-led activities due to the area's sensitive habitat, but all activities are free.
