Rostrevor Oakwood is a area of 250-year-old oak trees within the forest. They are the remains of the oak woods that were present on the lower Mourne mountains until it was mostly felled for use in boat building in the 18th and 19th centuries. The area is protected as a Special Area of Conservation. A clearing on the southern edge of the oakwood is known as Fiddler's Green and was at one time a gathering point in the village and would have featured various forms of entertainment. Every July since 1986, the village has hosted a traditional music festival named the Fiddler's Green Festival.
