The reserve lies north of the town of Enchi, forming an approximately crescent-shaped block of forest with the contiguous Tano-Anwia and Tano-Ehuro Forest Reserves (GH020, GH021). Yoyo is also connected to the Boin River Forest Reserve (GH005) by a narrow strip of forest, the Disue Forest Reserve. The area is drained by the Yoyo river and several other streams whose valleys become swampy during the wet season. The central portion of the reserve is mostly primary forest, but there are a few farms. The reserve was formerly under two timber concessions and the eastern and western parts were logged between 1962 and 1979.
