Better Birding Basics: Birding by Ear in Agua Chinon

Interpretive
Better Birding Basics: Birding by Ear in Agua Chinon

Birds are often hidden from sight and yet can still be identified by their calls and songs. Knowing how to identify birds by ear is an important step in becoming a better birder. Join other birders as we search for birds by both ear and eye in the beautiful arroyo canyon of Agua Chinon, part of OCParks’ Irvine Ranch Open Space. Restoration of this sensitive habitat has recently been completed, and we are watching to see if bird populations increase over time. Please wear sturdy shoes suitable for hiking, along with sun protection such as a hat and sunscreen.

Reviewing the 1-through-5 Difficulty Ratings will help you evaluate your readiness to participate in this level-2 activity on the land. Please visit our FAQ page for answers to activity specific questions you may have prior to registering.

Morning Yoga Hike at Quail Hill

Hiking & Fitness
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 hike is highlighted with a short but steep climb at a medium pace and takes us to a 360 degree view of the Quail Hill neighborhood. 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.

Moderate Paced Mountain Bike Ride: Baker and Fremont Canyons

Enjoy riding in the wilderness on empty trails? Then join us on a docent-led mountain bike ride that loops through Fremont, Baker and Black Star Canyons. The route features expansive views, as well as the flora and fauna of the Fremont Canyon Nature Preserve and Black Star Canyon Nature Park. If you are very physically fit and in excellent cardio shape, this is a great opportunity to enjoy this seldom visited wilderness of Orange County!

This is a moderate-paced ride designed for the experienced beginner to intermediate rider who is in excellent cardio shape and is physically fit, but sometimes needs to move slower on steep ascents/descents. We will ride both fire roads and largely non-technical single track trails. The ride will regroup and rest as needed and an opportunity will be provided for a snack break.

Please note, the ride is approximately 15 miles long with 2300 feet of elevation gain. The route has climbs with some extended steep sections.  The climb to Cathedral Rock is a 3+ mile climb that gains 1500+ feet in altitude (average 9% gradient with a number of steeper pitches).
