If you miss the signs, the route follows the Baranailt Road (B69) then on the left you follow the Drumrane Road which will take you up one side of the Roe valley to Dungiven. Dungiven is located where three rivers merge, the Roe, Owenreagh and Owenbeg, it is on the main road from Londonderry to Belfast. From Dungiven you will follow the Ballyquinn Road (B68) back down the other side of the Roe valley to Limavady. The river has a reputation to be good for salmon and sea trout and there are a couple of great locations to stop off and enjoy it. The scenic route is also the access route for the Roe Valley Country Park which is signposted, this is a fabulous setting with walks stretching over 10km beside the river.
