This week in OC Parks’ Irvine Ranch Open Space, we’ll hike in the remote Fremont Canyon. The hike is just under 6 miles and includes a steep hill. We will hike from the mouth of Fremont Canyon, past a historic coal mine, to the Fremont Weather Station. After enjoying a spectacular view, we will hike back the same way to our starting point. Please bring water, a trail snack, sun screen, hat, and any other necessary equipment to keep you safe on the trail and wear sturdy, closed-toe hiking shoes.

Please note, advanced registration required, no walk-up registration is permitted.
