Please see the Zoo Hours page for up-to-date seasonal hours and last-admittance times.

The Zoo is open every day, except Dec. 25.

If you must leave the Zoo for any reason during your visit and plan to come back, you’ll need to have your hand stamped in the Visitor Center near the main Connecticut Avenue entrance or at the Harvard Street pedestrian entry tent at the bottom of the Zoo. If you intend to leave and return within the same day, you must reenter the Zoo before last admittance.

Wheelchairs (free), strollers (rental fee) and electronic convenience vehicles (rental fee) are available to rent on a first-come, first-served basis at the Visitor Center. Zoo staff follow strict cleaning and disinfecting protocols between each rental use.

Degus have brown, silky coats on their backs and white fur underneath. They have squat bodies, and their hind limbs are shorter than their fore limbs. They have five clawed toes on their hind feet and four on their fore feet. Their tails are long with a brush-like tip.

They are common throughout their range and their populations are even on the rise because the expansion of humans has provided them with increased nesting areas. While they are often considered to be pests, degus are also becoming popular as pets and are sometimes used in research.

Wheelchairs (free), strollers (rental fee) and electronic convenience vehicles (rental fee) are available to rent on a first-come, first-served basis at the Visitor Center. Zoo staff follow strict cleaning and disinfecting protocols between each rental use.
