Along River Suir, Marlfield Forest offers great walks. There are two waymarked trails in Marlfield property. The Glenbawn Loop (2.5kms, 1 hour, moderate) gives the walker a great overview of the forest including the riverside. The Fox Covert Loop (3kms, 1hr 20mins, moderate) takes in the ringfort of Dún Uí Faolain on the eastern end of the forest in addition to the wider forest.
From a biodiversity perspective, the wood is predominately broadleaved which has been planted with conifers and some other non-native species.
