Donard Bridge built in 1835 sits astride the Glen River. Upstream of the bridge are an array of picturesque cascades and waterfalls fringed by broadleaved woodland. The trail encompasses woodland of Scots and Corsican pine, planted in 1927 and designatedas a Heritage Stand. There are four waymarked trails within the forest which follow a circular route and return to Donard Bridge (apart from the Glen River Trail which takes you to open mountain). All trails involve sections of steep uphill climbs and descents over rough and uneven ground should be attempted only by the physically active with appropriate walking boots.
