The National Zoo is home to thousands of animals of nearly 400 different species, including popular panda boy, Tai Shan. See him (along with his parents) at the Asia Trail section of the zoo (mornings visits are your best bet). This section is also home to sloth bears, playful red pandas and fishing cats. At the new Kid’s Farm exhibit, children can help tend goats and donkeys, plus play with interactive exhibits that show how pizza ingredients go from the farm to pizza. This zoo is spread out and hilly, so be sure to wear comfortable shoes and bring (or rent) a stroller. Admission: Free. The extensive website has downloadable scavenger hunt lists like “Where Are the Wild Things” or Zoo-per Bingo, plus you can print the Stroller Brigade guide for touring the zoo with young children.

The National Zoo is part of the Smithsonian museums and is free to all guests.
