Don’t use Google Maps
We attempted to get here based on some GPS coordinates we found online (I later noticed Google has it listed as a campground in the same spot we were were looking at). However, we arrived at a locked gate with a “private property, no trespassing” sign and didn’t see any other way to get to where we thought the campground was. We had passed by the ranger station on the way and it was closed so we had to find a different spot. The official directions do seem different than where we were, so maybe try this way or get directions from the rangers: “From Santa Maria: Highway 166 to Sierra Madre Road. Sierra Madre Road to Miranda Pines Road. Take Miranda Pines Road to Forest Road #11N04 and make a right into Brookshire Campground.” If you can find it, make sure to have a California Adventure Pass ($5/day or $30/year).
