Start your weekend off by exploring the Agua Chinon wash and the Sinks through this self-guided opportunity. Designated trails will be open for self-guided trail use in OC Parks’ Irvine Ranch Open Space. Trail routes vary in distance and level of difficulty with choices ranging from easy one-hour walks to a strenuous 9.5 mile trek. Whether traveling by feet or on two wheels, this exploration day is a treasure waiting to be discovered by hikers and mountain bikers alike.

The Round Canyon Exploration opportunity is a quick out and back hike with a 2.5 mile gradual 370′ elevation climb into a small canyon oasis. Tucked into the western cismontane of Loma Ridge, this canyon is part of the Limestone Canyon Preserve and it is rich in biodiversity. After the 2007 Santiago Canyon Fire, this little canyon saw a sudden re-growth of uncommon flowers, specifically the Wild Peony. The high canyon walls create a wonderful slope effect to the local coastal sage scrub community, noting large patches of Prickly Pear Cactus, Laurel Sumac and Lemonadeberry Bush. This canyon is thick with Coast Live Oaks and offers a rich birding experience. To access Round Canyon, visitors will need to hike or bike 0.75 miles along a paved frontage road that includes a steep descent along a flood control basin before reaching the trailhead.

Visitors to the Open Space during this activity are able to hike or bike to both the West and East Sinks Viewing Decks as well as Round Canyon.

Reviewing the 1-through-5 Difficulty Ratings will help you evaluate your readiness to participate in this level-3 to 4 activity on the land.

Please note that you will be asked to adhere to the following protective measures during the activity in order to participate:

• All participants are required to have a printed copy of their confirmation form for entry to this event. Please be registered in advance, no walk-up registration is permitted and there will not be on-site registration.
• Participants are required to stay on designated trails at all times.  Reminder: The Mesa trail system has rare and sensitive habitat. Your responsible behavior helps ensure continued access. This area is characterized by certain inherent dangers including mountain lions, rattlesnakes, poisonous insects, poison oak, ticks, extremes in weather, loose rocks, and steep/rugged terrain. Your safety cannot be guaranteed.
• Arrive with all necessary equipment to keep you safe on the trail, including plenty of water, proper attire to protect you from the sun and closed-toe footwear, first aid, medications, hand sanitizer, etc. Please see Trail Tips on the Lets Go Outside website for more tips.
• Maintain proper physical distancing, a minimum of 6 feet, between yourself and participants who are not in your household.
• Bring and make use of recommended facial coverings while in the staging area and when on trail if you are unable to maintain 6′ of distance from others.
• There will be one-way directional signs on the trail system. Follow these signs for the safety of all trail users at the event.

Other Important Notes:

• Dogs are prohibited. A dog’s presence and lingering scent disturbs wildlife and disrupts vital routines long after a dog has left the area.
• You may be prevented from participating if you do not adhere to the above protocols.
