Limestone Canyon is a treasure waiting to be discovered. Join us for an early evening, moderately-paced, 5.5-mile beginning cardio hike. The hike may include a few short rest stops along the way and will be a great introduction to fitness, cardio-style hikes as well as the magnificent Irvine Ranch Open Space.  Views of Limestone Canyon, and the surrounding wilderness, from Limestone Ridge will be the highlight of our tour.

Please bring a minimum of 48 oz. water. Come prepared with a pack, sturdy closed-toed hiking shoes or boots, sunscreen, first aid, and all other supplies to keep you safe and healthy on the trail for this beginner cardio-paced (3-3.5 mph with very few stops) hike in a wilderness area. Each participant must carry his or her own pack and water.  Under-prepared participants may be denied access to this program.
