    Started by cox park in crown valley and pedal my way into the park. If you are new to his sport this is a great place to be, however if you are on the next level and what to have a bit of adrenaline go to water works trails o. Your ride side by oso pkwy bridge
    There is a lot of hidden trails

    This rating because Trabuco creek running so deep that the trail and the road in the park are not passable. Single track has lots of ruts from recent rail storms

    Riding in O'NEIL park is great for beginning and the like. Riding out of the park South towards OSO, which is best know by the locals as the "Jungle" it's not a hard ride, but it is fun. 4 small water crossings and some minor hills to clime.

    O'Neill Park has probably one of the best beginner trails I've seen. The Tijeras Creek/Arroyo Trabuco loop is a 13-mile loop that has a couple of moderate climbs combined with lots of easy singletrack and fireroad. The best part is that the trail feels amazingly remote for being right in the middle of suburbia.

    The park trails are also easily linked to pretty much every other trail system in South Orange County with connectors that will get you to the Cleveland NF, Whiting, Aliso, Caspers, El Moro and even San Clemente.

    Reviewing Live Oak Trail:

    I used this trail to loop to Whiting (Dreaded hill to 4 corners) and Luge. Turn back at Cooks Corner to complete the ride from O'Neill Regional Park. Makes for an epic ride!

  • Reviewing Live Oak Trail:

    Live Oak is a pretty short trail, but I really enjoy it. Good combination of tight turns, a few dips, roots, and pretty good speed. I like to head up Serrano Creek and then come down Live Oak. Good workout to do that loop 3 or 4 times.
