On Aug. 25, the National Park Service turns 99 and Pinnacles National Park invites the public to celebrate the birthday on the weekend of Aug. 21, 22, and 23. A variety of special programs and activities will be available for visitors of all ages to enjoy. These will include a new Junior Ranger Cave Scientist Book, art activities, evening amphitheater programs and ranger-led hikes.

This birthday brings the National Park Service one year closer to its 100-year anniversary in 2016. Visitors can participate in events and explore a National Park that is full of natural, historic, and cultural beauty. Organizers say the event is designed to help people appreciate the past and discover ways to protect Pinnacles National Park for future generations.

In addition, the National Park Service is offering free admission to all National Parks on Founder’s Day – Tuesday, Aug. 25.
