R251 road (Ireland)

The R251 road is a regional road in Ireland. It is located entirely in County Donegal and runs in a northerly then westerly direction from its junction with the R250 road west of Letterkenny to the N56 east of Gweedore. The route is very scenic: it passes Glenveagh, skirts around the base of Errigal and offers excellent views of the Derryveagh Mountains.
