CANCELLED due to Trail Conditions: Pulling Together at Quail Hill

North African Knapweed, Centaurea diluta, is a recently introduced invasive plant and we need your help to get rid of it! Invading weeds degrade habitat for wildlife, exacerbate wildfire risks, and reduce overall biodiversity. Help us keep wildlife healthy by weeding North African Knapweed from Quail Hill in Irvine.
This activity takes place on some uneven terrain, and sturdy hiking boots are highly recommended. Training and tools will be provided to ensure your safety and comfort. Rattlesnakes are occasionally seen here and generally avoid people, but protective gear will be provided.
We will meet at the Quail Hill Trailhead parking lot, then walk 15-20 minutes on a bikeway adjacent to the 405 Freeway to the work site.

Morning Yoga Hike at Quail Hill

Enjoy a 3.6 mile out and back hike to warm up your legs before experiencing a gentle flow yoga practice in nature.

The yoga is suitable for those with little or no experience; slower in pace and gentle in practice. Our focus on breath calms the nervous system and has positive effects on mental, emotional and physical health. If you have never done a yoga hike before you will be surprised how connected you feel to nature. Please bring water, your own yoga mat plus a large beach towel, and wear shoes appropriate for hiking on trails.
