In 1971, Swiss agronomist Dr René Haller began the unlikely experiment of rehabilitating an exhausted limestone quarry behind the Bamburi Cement factory. Starting with the hardy casuarina tree, he built up soil, planted hundreds of indigenous species, and gradually attracted insects, birds, fish, and mammals. Fifty years on, Haller Park is a 75-hectare reserve and an internationally celebrated case study in ecological restoration. It hosts giraffes, hippos, crocodiles, eland, oryx, waterbuck, monkeys, tortoises, and over 160 bird species all on land that was once a bare quarry floor. Daily highlights are the giraffe feeding sessions at 11:00 and 15:00, when visitors stand on a wooden platform and offer leaves directly to the giraffes’ purple tongues. The crocodile feeding at the reptile park is a riveting (if slightly grisly) demonstration of African crocodilian power. Walking trails wind past the famous Mzee and Owen, the rescued giant tortoise and orphaned hippo who became inseparable friends and the subject of a bestselling children’s book, through butterfly pavilions, fish farms, and palm groves. A reforestation interpretation center tells the Haller story and underpins the park’s reputation as one of the most ethical wildlife experiences on the Kenyan coast.
