The new African Gorilla Forest was one of the most highly anticipated exhibits at the Houston Zoo. After a 10-year hiatus, the Houston Zoo is now home to seven gorillas that are broken up into two groups: the first is a family unit of three (mother, father, and child) and one single female, and the second is a group of three bachelors. The two distinct troops of gorillas will spend their days alternating between an outdoor habitat and a multi-tiered night house that includes private bedrooms, an artistic 23-foot tall climbing tree, and a behind-the-scenes outdoor yard. The forest is a state-of-the-art natural habitat with features that include a waterfall, flowing stream, natural and artificial logs, and boardwalks where visitors can get a closer look. There is also a huge, sloping berm with a dense forest and moat.
