Castle Crags State Park 1:50,000

Castle Crags State Park is one of the great unknown wonders of California. Most people only glimpse it as they scream by on I5, but it richly rewards a day, or a week, of exploration.

Rock climbers know Castle Crags as home to The Cosmic Wall of Mt Hubris, one of the best multipitch 5.7 routes in the country.

Now you can hold its towering granite plutons in the palm of your hand.
