Krokosua Hills Forest Reserve is located in southwestern Ghana, to the east of Bia National Park. The reserve was established in 1935 (UNEP-WCMC and IUCN 2019), and it consists of two forest blocks, one above and one below the Asempaneye-Kumasi road (Ernst et al. 2008). The highest peak at the site is 594 m (Ernst et al. 2008). In addition to the western chimpanzee (''Pan troglodytes verus''), other fauna found at the site include the western tree hyrax (''Dendrohyrax dorsalis''), royal antelope (''Neotragus pygmaeus'') (Oates 2006), olive colobus (''Procolobus verus''), black and white colobus (''Colobus vellerosus'') (Danquah et al. 2012), and a frog species discovered in the reserve, ''Arthroleptis krokosua'' (Ernst et al. 2008).

Traces of chimpanzees have been encountered during surveys, in 2005 (Oates 2006), 2006-2008 (Gatti 2010), and more recently in 2009 (Danquah et al. 2012), but population estimates are not available. The site has also been identified as the most likely to support a fairly large population of chimpanzees in Ghana (Caldecott & Miles 2005).

The lowlands in Krokosua Hills Forest Reserve have been heavily logged in the past, but the forest in steeper areas has been less affected (Oates 2006). Illegal farming activities have also been found inside the reserve (Oates 2006). Another major threat to chimpanzees at the site is hunting, which appears to be very high (Oates 2006, Danquah et al. 2012).
