Haller Park in Mombasa: From Quarry to Nature Park

Haller Park in Bamburi turned a barren limestone quarry into a living nature park. Its story, its animals and how to fit it into a coast trip.

Haller Park is one of the most unusual wildlife stops in Kenya, because the habitat itself is the story. What is now a green park was once a scarred limestone quarry.

How it began

The site in Bamburi, near Mombasa, was a set of limestone quarries from a cement works. Rehabilitation began in the late 1950s. Rene Haller was hired in 1959 and led the reforestation effort from the 1970s. Of 26 trial plants, only three survived. Casuarina trees were planted first to colonise the quarry floor, and millipedes helped build the soil.

What you can see

  • Giraffes.
  • Crocodiles, in an area that is part of the park’s aquaculture system.
  • Fish and tilapia farms and water treatment ponds, showing how the system works.

Who it suits

It suits families and anyone with a half day on the coast, especially after a safari. Read our guides to safaris with kids and teenagers.

Making the most of it

  • Go in the cooler part of the day and bring water and a hat.
  • Ask about guided visits that explain the rehabilitation story.
  • Combine it with a Mombasa city tour or a beach day. See safari and beach holidays.

Why it matters

Haller Park shows what patient ecological restoration can achieve, and that conservation is as much about repairing habitat as protecting wild places.

Fish, eland and farming experiments

Fish farming began in 1971 alongside the reforestation project, and a tilapia farm added in 1980 produced 30 to 35 tons a year. Elands were chosen for domestication trials because they give nutritious milk, resist most livestock diseases and tame easily.

An impossible task

When Bamburi Cement decided to rehabilitate the worked-out quarries, the task seemed impossible. Today the site is a working example of how a damaged landscape can be rebuilt.

Owen and Mzee

The park became widely known for the friendship between a hippo, Owen, and a tortoise, Mzee. It featured the pair up to March 2007.
