Caher forest is situated on the eastern foothills of the Galty Mountains in south Tipperary, adjacent to Cahir and covers a total area of 3,556 hectares. It is a large block with three small detached properties, Boolakennedy, Garryclogher and Cahir Park. The River Suir flows through the forest.

Caher forest was established by the Chartrisis/Butler estates during the nineteenth century when Scots pine, Douglas fir and oak were the main species planted. Today the main species are Sitka spruce, Japanese larch and 6% broadleaves. The main soil types are old red sandstone podsols and brown earths. Both the oak wood in Scaragh and Caher Park property are Special Areas of Conservation. Caher Park is a fine example of Irish yew woodland. This stand of yew may have survived from ancient times as a relict woodland on a limestone outcrop, and may have been protected from felling by virtue of its location in the Charteris Estate.

Caher Park is managed for recreation purposes and contains the Swiss Cottage which is managed by the OPW and is open to the public.

Walking trails within the forest include way-marked ways, St. Declan’s Way and local heritage walks. There are also fishing opportunities.
