55°01′30″N 6°56′20″W / 55.025°N 6.939°W The Roe Valley Country Park is a forested area containing part of the River Roe, south west of Limavady, County Londonderry, Northern Ireland. It is maintained by the Northern Ireland Environment Agency, which is part of the Department of the Environment of Northern Ireland.
The park is approximately three miles (4.8 km) long and consists of mainly deciduous, riparian woodland on each side of the Roe. The terrain next to the river is mostly steep sided gorge, with some areas of flat grassland on the northwest bank. As the river has a large, freely draining catchment area, it significantly increases in volume and speed soon after heavy rain.[1] This is most visible around the visitor centre, where the river is forced through a narrow section of the gorge. The river is known for the legend of the dog who leaped the river Roe, fleeing enemies to warn the O'Cahan's of Limavady of danger via a message in its mouth.
