The Smithsonian's National Zoo and Conservation Biology Institute is committed to saving species and our planet. Did you know that the Zoo recycles approximately 100 tons of materials and composts 600 tons of waste each year?

This Earth Day, make the Zoo your go-to place to participate in green-themed activities. You'll have the chance to get gardening tips from our expert horticulturists, take a tour of the Zoo's green facilities, attend special demonstrations, and more. Don't forget to ride your bike!

2016 Special Activities


Take a ride on the sustainable side, and join the Zoo in its inaugural Bike to the Zoo event this Earth Day! Choosing to ride a bicycle instead of driving is a great way to lower your carbon footprint and help protect the planet.

The first 75 bicyclists to register for this event will receive free bike valet parking at the Zoo and a free recycled notebook! Register now by filling out the form below.

Bike to the Zoo Registration Form

Registered cyclists will receive a confirmation email within three business days of submitting registration.


Discover new ways to reuse everyday household items before they head to the recycling bin at this Earth Day display! Find out how a milk jug can be turned into a scoop, how tin can lids can transform into garden signs, how a t-shirt can become a tote bag, and much more.

Zoo staff and volunteers will be on hand to offer ideas and instructions on how to turn recyclables into do-it-yourself crafts and items that can be used around the home. Visitors will also have the opportunity to create their own "lights out!" door hanger using bottle cap stamps to encourage sustainable habits at home!
