Coedydd Maentwrog National Nature Reserve

Coedydd Maentwrog, on the north side of the Vale of Ffestiniog, is the largest wood in the Vale. The national nature reserve consists of two separate sections: Coed Llyn Mair, and a group of three forests. It offers a variety of habitats, rising from the wooded valley onto open moorland and reaching towards the foot of Moelwyn Bach mountain. A nature trail and a network of public footpaths are features of the reserve. Animals such as the rare lesser horseshoe bat and the wood warbler can be spotted here, and the gorge is noted for its liverworts and lichens. ()
