Rocky promontories, panoramic views, kelp-dotted coves, and the dramatic sounds of pounding surf; open grasslands, forested hills, pristine prairies, and pygmy forests- you can experience all of these coastal wonders within the Salt Point State Park. With 20 miles of hiking trails, over six miles of rugged coastline, and an underwater park, you can enjoy a variety of picnicking, hiking, horseback riding, fishing, skin and SCUBA diving, and camping. The weather can be changeable along the rugged Northern California Coast. Even summertime can be cool as fog hugs the coastline and ocean winds chill the air. We recommend layered clothing for your visit. Sandstone and Tafoni Ever wonder where the streets of San Francisco came from? Sandstone from Salt Point was used in the construction of San Francisco's streets and buildings during the mid 1800's. If you look closely at the rocks at Gerstle Cove, you can still see eyebolts where the ships anchored while sandstone slabs were loaded onboard. Quarried rocks can still be seen scattered along the marine terrace north of Gerstle Cove. Look for the drill holes along the edges of the rocks that were used to separate the large rocks into smaller slabs. Tafoni is the Italian word for cavern. It is a natural phenomenon that is common along the sandstone near the ocean's edge at Gerstle Cove and Fisk Mill. Look for a honeycomb type network carved into the rocks forming pits, knobs, ribs, and ridges. For more information on the geology of Salt Point click on link to the left.
