The Nine Sisters of San Luis Obispo

The Nine Sisters of San Luis Obispo, CA

One of the most amazing natural wonders of San Luis Obispo are the Nine Sisters or the Morros.

The amazing mountains are a chain of nine volcanic mountains and hills in western San Luis Obispo County, central California.

They run from Morro Bay east through San Luis Obispo.

The peaks were created over 20,000,000 years ago during the Miocene Epoch of the Neogene Period, as volcanic plugs of magma which welled up and solidified inside softer rock which has since eroded away. The highest plug is Bishop Peak at 1,559 feet (475 m).

As you can imagine their volcanic origin makes them of significant geological interest. They are popular with photographers and rock climbers.
