A refuge for more than 500 drills, an extremely endangered monkey.

Founded in 1991, Drill Ranch is the region’s first primate rehab project. Illegally held drills orphaned by hunting are donated by local citizens or handed over after seizure by authorities; no animals are purchased or removed from the wild. Over 75 drills have been recovered, and rehabilitated to life with members of their own species, after thorough medical screening. Visit Website.

Interested in Visiting or Volunteering?


Drill Ranch accepts committed and skilled long-term volunteers. They are interested in a diverse set of skills not limited to animal experience or degrees. The most important qualities are a serious interest and the willingness to work as part of a team.


Drill Ranch project sites are open to the public free of charge, 365 days a year. Thousands of people, mostly local citizens who share the drill’s habitat, thus have the opportunity to see natural-sized drill family groups and chimpanzees and learn about the animals and the challenges these species face in the wild.
