Cheeseboro/Palo Comado Canyon is a 20 mile hiking trail in Agoura Hills, California.
Take 101 to Chesebro Rd. Yes, the road name is spelled differently than the trail name. Head north and take a right on Cheseboro Rd. You'll recognize it because this area says "Old Agoura Hills", and you'll see signs warning you to be careful of horses. Follow the very narrow street a mile, then take the first right before the Agoura Hills City Limit sign. You can park right here, but if you hit the parking lot during less crowded times, you're more likely to get something closer to the trailhead.
