OC Parks invites you to discover Orange County’s ancient past through rare fossil displays on National Fossil Day. An OC Parks Paleontologist will be on site with a special pop-up fossil showcase on Tuesday, October 15 at the Visitor Center at Aliso and Wood Canyons Wilderness Park. This family-friendly drop-in interpretive experience will feature rare fossils from Orange County’s collection, offering a unique opportunity to explore the region’s prehistoric past. Come see fossils of ancient sharks, whales, seals and walruses, as well as strange animals like the mysterious Desmostylus. 

The program is free and parking is $3 per vehicle.

Join OC Parks staff and volunteers to observe the sights, sounds and smells of nature during an intimate nature walk led by a certified nature and forest therapy guide. Through a series of invitations, you will be encouraged to explore in the present moment and deepen your connection with nature. 

Please note this is a slow-paced program designed for ages 14 and older. Minors must be accompanied by a guardian.
