Small Mammal House
📍 Northwest Washington, DC
The Small Mammal House at the Smithsonian National Zoo on Olmsted Walk is home to a diverse collection of small and unusual mammals, including nocturnal species. Free as part of the zoo's no-admission policy.
🏆 Family Action Verdict
Best for families with kids ages 4 and up who are fascinated by unusual animals. The naked mole rat exhibit alone generates reliable excitement from children. The indoor setting makes it a strong wet-weather option within the zoo.

Overview
The Small Mammal House at the Smithsonian National Zoo houses an eclectic lineup of small and often rare mammals - including the famous naked mole rat colony, golden lion tamarins, and various nocturnal species visible in low-light exhibits. Reviewers describe it as a neat, interesting stop packed with animals many visitors have never encountered before. Located along Olmsted Walk, it pairs naturally with the nearby Great Ape House and Sea Lion Pool for a connected zoo loop.
