Irvine Ranch Natural Landmarks

Come enjoy a scenic fast-paced  twilight hike in the remote Fremont Canyon Nature Preserve. Our hike climbs steeply from the mouth of Fremont Canyon, past an abandoned coal mine, up to the Fremont Weather Station where winds have been clocked at up to 100 mph. After enjoying the view, we’ll turnaround and hike back the same way to our starting point.

This challenging hike involves steep hills and a 1200’ elevation change but the rewards are sweeping views at the magic hour of twilight, just before and after sunset. Please arrive 15 minutes early and come prepared with a sturdy day pack, water, snacks, closed-toe hiking shoes or boots, sunscreen, first aid, and all other supplies to keep you safe and healthy on the trail.
