Fort Casey State Park is offering a day of family fun Friday, Aug. 25.

Families will have the opportunity to touch a real gray whale skull, follow the journey of a salmon, learn how orcas hear sound and participate in many more activities.

Washington State Parks is hosting the family outdoor discovery event from 3-5 p.m. on Saturday at Fort Casey State Park. The free event will feature 12 activities sponsored by local organizations.

All the offerings are activity-based, said Sharon Young-Hale, program specialist for Washington State Parks.

Participants who do all the activities and turn in their completed “passport” will receive a badge and be entered into a raffle to win prizes. Adding to the day of fun, families are invited to stay past dark for an evening screening of “Lost &Found,” a movie filmed on Whidbey Island.

The movie is about brothers who spend the summer on a remote and mysterious island, embarking on a thrilling treasure hunt to restore their family’s lost fortune.

“The whole idea is to draw families in and then maybe they’ll stay for the movie,” Young-Hale said.

This is just one in a series of events Fort Casey is hosting in an effort to bring people to the park and as a way to be interactive with the community.

Aug. 25 is a state park free day, so attendees will not have to purchase a Discover Pass.
