Black Star Canyon or Canon de los Indios (http://www.irlandmarks.org/Explore/black-star-canyon.aspx) is located in the Santa Ana Mountains in Orange County. I had never heard about it until this week when they decided to have an open house for the public in celebration of this land gift from Irvine Company chairman Donald Bren.
This canyon was wild country at one time--populated with American fur traders, Mexicans, and horse-stealing Tongva Indians. There are stories of ghosts and ranchos. All I can say is that it's extraordinarily beautiful and a great place for biking and hiking and spinning a story.
The park is not easily accessible to the public. Today was one of those rare opportunities, although I believe you can get access if you participate in the docent-led activities. There are easy, moderate, and strenuous trails. Black Star Canyon Road connects to the Cleveland National Forest.
It's a beautiful, beautiful place. I will have to find out more about it--and the ghosts.
