Children of all ages are invited to bring their favorite adult and come to the National Junior Ranger Day celebration, 10 a.m.-2 p.m. Saturday, April 25, at the Olympic National Park Visitor Center, 3002 Mount Angeles Road, Port Angeles.

Activities are scheduled throughout the day, including an opportunity from 11 a.m.-noon to meet some of the park's pack mules and learn about their important role in maintaining Olympic's 600-plus miles of wilderness trails.

Junior Rangers can work with park botanists, repotting native plants grown in the park's greenhouse. Each year, park staff uses thousands of native plants to restore damaged areas within the park. Junior Rangers who participate in this activity will have the chance to bring home a native plant.

In addition, 40-minute ranger-guided walks are at 10:30 a.m., 11:30 a.m., 12:30 p.m. and 1:30 p.m.

Microscopes will be set up for in-depth views of insects and plants, the Children's Discovery Room will be open for play and exploration and the park's award-winning film will be shown.

"This will be a fun-filled day for kids and adults and a great way to celebrate National Park Week while learning more about Olympic National Park," said park Superintendent Karen Gustin. "We invite young people to bring their favorite adult on April 25 and enjoy becoming a Junior Ranger."

Children must be accompanied by an adult; all activities are designed to be fun and enjoyable for adults, too.

Olympic's Junior Ranger program is a year-round way for children and families to experience and enjoy the park. Children complete Junior Ranger activity booklets, attend a ranger program and explore park nature trails to earn a Junior Ranger badge and certificate.
