In 1875, the lighthouse was illuminated and it served as an aid to maritime navigation for many years. The lighthouse provided for the safe passage of mariners and it slowly transformed as buildings were added to support the light keepers and their families. As technology evolved, the operations and character of the light station changed. In addition, the ravages of time and natural forces, including earthquakes, took its toll on the structures (the top three floors of the light house were removed because of earthquake damage). Human impacts changed the natural landscape with the introduction of non-native vegetation.

Since 2002, the Bureau of Land Management along with the help of a band of dedicated volunteers have revived the site. Reintroduction of native plants and the return of wildlife is inspiring as is the restoration and rebuilding of historic structures. Installed interpretive trials and informative tours now provide visitors with a one-of-a-kind experience. Today, Piedras Blancas Light Station continues to evolve as an unparalleled historic park and wildlife sanctuary. It boasts spectacular scenic vistas, an abundance of native plants and animals, and is home to one of the most architecturally stunning lighthouses on the Pacific coast.

It is a place where visitors can explore the historic past and enjoy the sights and sounds of California's unspoiled central coast.
