Nine lemur species live within the park, seven active during the day and two nocturnal. Most arrived as confiscated pets, animals that had been kept in homes and lost the skills needed for survival in the wild. The park's staff work to rehabilitate these lemurs and gradually reintroduce captive-born animals into natural habitats. Since 2007, Lemurs' Park has successfully bred Coquerel's sifakas, one of the more charismatic and endangered species, a quiet achievement that speaks to the quality of care in a facility that could easily be dismissed as a tourist attraction. Featured feeding times occur every two hours between 10 a.m. and 4 p.m., when visitors can watch the free-ranging lemurs interact at close quarters. The park also maintains a vivarium housing chameleons, radiated tortoises, iguanas, and other reptiles.

The botanical side of Lemurs' Park is substantial. Nearly 6,000 trees and more than 70 endemic plant species fill the grounds, organized into separate climatic zones that represent Madagascar's ecological diversity. Saplings of baobabs and other endemic plants from the spiny thickets of southern Madagascar have been transported to the park and planted alongside rosewood, Terminalia, and amontana trees. This is not just landscaping. Madagascar has lost the vast majority of its original forest cover, and every surviving patch of endemic vegetation, even a small cultivated one, contributes to the genetic reservoir that reforestation depends on. The park sits between the villages of Fenoarivo and Imerintsiatosika along Route Nationale 1, positioned where the capital's urban sprawl begins to thin into the countryside.

Between December 2008 and May 2013, approximately 37,163 students and 1,270 teachers from public primary schools around Antananarivo visited Lemurs' Park to plant native trees and participate in environmental education. For many of these children, the visit was their first time seeing free-ranging lemurs. That number matters in a country where deforestation has made lemurs increasingly rare outside of protected areas, and where the urban population has limited access to the natural heritage their island is famous for. The reforestation program, supported by Colas Madagascar and Total Madagascar, has planted more than 11,000 trees as of 2013. The corporate partnership has also helped the park retain its staff during economic downturns, with over 90 percent of employees drawn from the surrounding communities. Conservation in Madagascar often depends on these kinds of pragmatic alliances between international companies, local institutions, and the communities that live closest to the forests.

Lemurs' Park is open year-round, seven days a week, and does not require advance booking for walk-in visitors. A park shuttle departs from the heart of Antananarivo at Analakely at 9 a.m. and 2 p.m., with the shuttle fare including park admission. Guided tours are mandatory, and stays are limited to 90 minutes, a constraint that keeps foot traffic manageable in a small space. The park has a restaurant, though it requires 48-hour advance booking. The accessibility is the point. Madagascar's most famous wildlife reserves, places like Andasibe-Mantadia or Ranomafana, require hours or days of travel from the capital. Lemurs' Park puts the experience of walking among free-ranging lemurs within reach of anyone with a morning to spare. That proximity to Antananarivo, home to more than two million people, makes it as much an educational institution as a conservation one.
