KWPLH Balikpapan is a conservation centre focused on the Malayan sun bear, the small forest bear that has become a symbol of Balikpapan. It is not a polished zoo; the value is in seeing a local conservation project close to the city and understanding the pressure on Kalimantan's lowland forests.
The centre makes a good pairing with Wain River Protected Forest or Bukit Bangkirai if you are trying to see the greener side of Balikpapan. Go with modest expectations and treat it as an education stop rather than an animal-show attraction.
