We are excited to welcome you to the Upper Newport Bay for our annual Earth Day celebration! Join us for a free family-friendly day full of hands-on arts and crafts, educational activities, and science discovery. Enjoy live music as you explore our Adventure Partners’ booths, take a break for a tasty treat at one of the food trucks, and don’t forget to complete the scavenger hunt for prizes and giveaways! We hope to see you there!

On Earth Day we need you to take a stand so that together, we can show the world a new direction – to think about how we can protect our planet and preserve it for the future.

For 56 years, Earth Day has been bringing communities and organizations together to advocate for a healthier environment and a sustainable life. The first Earth Day on April 22, 1970 activated 20 million Americans from all walks of life to share their concerns about each citizen’s critical role in the environment. Their actions led to the creation of the U.S. Environmental Protection Agency and the passage of the Clean Air, Clean Water, and Endangered Species Acts. Now over one billion people in 192 countries participate in Earth Day activities, making it the largest civic observance in the world.
