More About Castle Rock State Park

Castle Rock State Park is best known for the sculptural sandstone rock formations that lie within its mixed evergreen forest of black oaks, knob-cone pines, and coast redwoods. The 5200 acres of parkland contain 34 miles of trails which connect it, via the Skyline to the Sea Trail, all the way to the coast.

About 30 to 40 million years ago, deposits below the sea accumulated on the continental shelf in the area which is now Castle Rock State Park. As the San Andreas Fault caused movement and elevation of this area, these outcroppings of Vaqueros sandstone rose and eroded into the fascinating shapes we see today. Transformation of this rock is ongoing. Sandstone is soft and porous, and during the wet season rain water seeps into the rock, slowly dissolving the minerals that hold the sand grains together. As it dries, the rock crumbles and erodes, and new shapes emerge.
