Limestone Canyon Nature Preserve

Nature must have been in an especially creative mood when Limestone Canyon was formed: From a striking formation known as “The Sinks,” to a year-round dripping spring in a verdant grotto, to thick oak woodlands, the canyon has something for every outdoor adventure-seeker. Not surprisingly, Limestone is a favorite destination on The Irvine Ranch for hikers, mountain bikers, painters, photographers and naturalists.
