Maryland Zoo in Baltimore (Druid Hill Park)

The Maryland Zoo in Baltimore occupies 135 acres of Druid Hill Park in northwest Baltimore, Maryland, and has operated continuously since 1876, making it one of the three oldest zoos in the United States. The collection houses approximately 1,500 animals representing more than 200 species across themed habitats. The African Journey section is the zoo's flagship area, presenting black rhinoceroses, African elephants, Grant's zebras, lions, and meerkats in expansive naturalistic enclosures that allow animals substantial freedom of movement. Penguin Coast is home to the largest colony of African penguins at any North American zoo, with above-water and below-water viewing windows and daily keeper feeding demonstrations. The Maryland Wilderness section features native mid-Atlantic species — river otters in a creek habitat, bald eagles with permanent wing injuries, and great horned owls — displayed in reconstructed Maryland wetlands, forests, and meadow environments. The Children's Zoo within the main zoo grounds offers contact experiences with domesticated animals, a goat feeding station, and a carousel, providing a gentler animal experience for very young visitors. The zoo operates an active conservation program for the endangered African penguin, funding breeding research in coordination with South African wildlife organizations. A 1.5-mile walking loop connects the primary exhibit areas; weekend tram service assists visitors who cannot walk the full circuit. Admission prices are competitive compared to major urban zoos, and Maryland residents may access discounted tickets through the zoo's library card partnership program. The surrounding Druid Hill Park offers free recreational space with reservoir views and walking paths that can extend a visit after zoo closing time.
