Celebrate our planet at Tulsa Zoo with music, green-themed activities for kids, a Green Market featuring earth-friendly vendors and more. Don’t miss the Discovery STOMPS across the zoo to learn how you can make a difference for animals across the globe, like rhinos and monkeys, by acting locally. Learn how to make your own compost and how to make recycling a cinch. Plus, the folks at Tulsa Zoo are still celebrating APE-ril, so be sure to cruise down Ape Avenue to do a little monkeying around and test your ape aptitude. Bring an old cell phone to recycle and get half off the price of admission the day of Party for the Planet (one discount per phone). Every phone donated not only saves the planet, but also benefits your Zoo. Through 5pm.
