About Quail Hill Trailhead 

The 2.8-acre Quail Hill Trailhead provides a great location to connect to southern Irvine’s extensive trail network. The trailhead is located at the end of Sand Canyon Road and marks the beginning of the Quail Hill Loop Trail, an easy two-mile natural surface trail at the foot of Quail Hill that is open to the public from dawn to dusk. Irvine’s southern wilderness is also accessible via docent-led activities that begin at the trailhead. Quail Hill Loop Trail is the only wilderness trail in the Natural Landmarks that allows dogs – on leashes.

While visiting the Quail Hill Loop Trail, bring along your cell phone and experience Irvine’s self-guided cell phone audio tour. Just dial in to hear natural resource interpreters and researchers explain important features along the trail. The tour itself is free, but you will use your own cell service and minutes. Additionally, the tour can be listened to on any phone, anywhere, any time.

How to listen: Dial 949-743-5943. Listen to the greeting and then enter the number of the location you are interested in followed by the # key. The locations are numbered 1-5, and you can leave anonymous comments by pressing 0# at any time. The prompts can be listened to in any order.

The audio tour is also available in a podcast format. You can listen on your computer or cell phone. Learn more at letsgooutside.org
