This is a nice little loop around El Moro (now known as Crystal Cove). Some fun climbing, some fun downhill, some fun singletrack but mostly fire road. Nothing too techy.

Crystal Cove State Park is a 2,400-acre park filled with singletrack trails and double-track roads that are great for biking. Depending on what bike you're on, you might want to stick to the smoother dirt roads. A lot of people hike and run on the trails, too, so don't get too sendy on blind curves.
