Hiking & Fitness
Valentine's Day Fitness Hike with Yoga at Bommer Cattle Camp

Show yourself some love this Valentine’s Day by joining us for a five-mile moderate fitness hike (averaging about 3 mph) with rolling hills before experiencing yoga the Cattle Camp. This historic old west setting connects us with the history of The Irvine Ranch and the barn’s outdoor stage is perfect for yoga. The hike is highlighted with beautiful views of the canyon and the yoga is suitable for those with little or no experience, focused on hips, legs and core. Our focus on breath calms the nervous system and has a positive effect on mental, emotional and physical health. If you have never been to the Cattle Camp before you will be surprised how connected you feel to the cowboys that worked on this land. Please bring water, a yoga mat plus a large beach towel and wear shoes appropriate for hiking.
