Tollymore Forest Park was the first state forest park in Northern Ireland, established on 2 June 1955. It is located at Bryansford, near the town of Newcastle in the Mourne and Slieve Croob Area of Outstanding Natural Beauty. It covers an area of 630 hectares at the foot of the Mourne Mountains and has views of the surrounding mountains and the sea at nearby Newcastle. The Shimna River flows through the park where it is crossed by 16 bridges, the earliest dating to 1726.
