Just prior to entrance of Julia Pfeiffer State Park. Not marked by signs but it is shown on a good area hiking map. A fire road goes down to the cave from a pull-off right on Route 1 at a big U-turn just prior to the park going south. The Partington family used the cove as an unloading dock for cargo prior to the road being built. To see the area used for unloading you have to cross the foot bridge and pass through the hand excavated tunnel. Really cool.
