I had some time to kill on my way back to the airport, so I stopped by Vasquez Rocks. This park is in Agua Dulce, about an hour from LA. The rock formation is famously used in Hollywood movies, especially westerns. According to the exhibit, it is named after Tiburcio Vasquez, a bandit, who used the area as a hideout. The park claims they are the only one named after an executed criminal.
There are not many trails in the park, so you could see the entire park in a few hours. The PCT runs through here just after crossing route 14, so I was able to walk a short section.
