Irvine Ranch Natural Landmarks

The Irvine Ranch Natural Landmarks extend across 40,000 acres of preserved terrain, featuring coastal sage scrub, chaparral, and Tecate cypress woodlands.

The land operated as a cattle ranch from 1860 until the late 1970s, when conservation efforts transformed it into a protected natural space.

The area received National Natural Landmark status in 2006, joining fewer than 600 sites nationwide with this federal designation.

Visitors can access numerous trails throughout the preserve, including the Mountains to Sea Trail that connects different ecosystems across the region.

The geological formation known as the Sinks in Limestone Canyon displays rock layers spanning 80 million years of Earth's history.
