Twilight Hike: Fremont Canyon

Hiking & Fitness
Twilight Hike: Fremont Canyon

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.

OC Parks invites you to lend a helping hand and join volunteers around the world for Coastal Cleanup Day. Make an impact on our coastlines as we work together to remove trash and recyclables from the marsh, waterway and beaches.

Get ready to get dirty! Please wear old clothes and closed-toed shoes or rain boots as most locations are muddy. Help reduce waste by bringing gloves and a bucket if you have them. You can also bring a reusable water bottle.

Everyone will not start at the Peter and Mary Muth Interpretive Center for this event. *NEW THIS YEAR* volunteers will meet directly at 20-25 different mini-cleanup day sites around the 11-mile bay including the Peter and Mary Muth Interpretive Center, Newport Aquatic Center, Big Canyon, Vista Point, Jamboree Bridge, etc. Commit and register to attend early to help us coordinate everyone.

Bats: Heroes of the Night

Interpretive
Bats: Heroes of the Night

As the day starts to settle into the night, bats awaken, stir and streak into the evening sky. Come hear fascinating tales of our flying mammal. We will head out towards a popular roosting location as we watch our nighttime heroes begin their nightly adventures. This program is ideal to visually observe the bats in flight, though bat detectors are available to listen for their high-frequency calls.

Be prepared to walk about 1/2 a mile. Dress warmly as it may be a chilly evening. A camping chair is welcome as we will enjoy an extended period of time listening for bats that fly about in the night.
