Inishowen Peninsula Circuit

At the intersection of the R238 with the N13, to the south of the R239, stands a notable modern church dedicated to St Aengus (by MacCormick and Madden), a circular structure with a ring of windows and a curving tent roof surmounted by a glass pyramid. Its form may have been influenced by the Grianán of Aileach (National Monument), 2.5mi/4km away to the south.

At Clonmany join the R238. 2mi/3km east is Ballyliffin, near the 2mi/3km long Pollan Strand.

The Vintage Car and Carriage Museum is near Buncrana and has a collection of vintage cars, carriages and Victorian bicycles.

At Carrowmore there is a group of high crosses (National Monuments).

Near Cludaff is Clonca, which has a ruined church, a fine but badly weathered high cross with a representation of the Miracle of the Loaves and Fishes, two male figures and geometric ornaments, and a finely carved tombstone (National Monuments).

South of Glengad Head is Cludaff, a fishing center (sea trout).

In the dunes of the Doagh Peninsula are prehistoric rubbish dumps, in which highly interesting discoveries have been made. Picturesquely situated at the northern tip of the peninsula are the ruins of Carrickabrahey Castle.

The magnificent scenery of the Inishowen Peninsula is best seen when traveling from south to north. At the north end of the road Dunaff Head has magnificent cliffs (much frequented by rock climbers) and beautiful views.

From Buncrana the best plan is to take the byroad which goes northwest to Dunree Head (beautiful view from lighthouse).

3mi/5km northwest of Griánan of Aileach lies Fahan, on the shores of Lough Swilly. In the old monastic churchyard adjoining a modern church is a very ancient cross-slab (eighth century), with two crudely carved figures flanking a cross of elaborate interlace work; on one of the edges is a Greek inscription (a rarity in Ireland).

The byroad going northwest from Buncrana to Dunree Head leads over a breathtakingly steep pass (gradients of up to 30%), the Gap of Mamore.

From Malin Head a long range of cliffs up to 790ft/240m high extends southeast to Glengad Head.

2.5mi/4km northwest of Molville lies Greencastle, with the ruins of a large castle (1305: National Monument). Nearby is a Martello tower of 1810 (now a hotel).

0.75mi/1km west of Cardonagh is Hell's Hole, a narrow gaping chasm which, with an incoming tide, is awesome to behold.

From Moville the R241 goes northeast to Inishowen Head, from which another range of magnificent cliffs (with views of Northern Ireland on the far side of Lough Foyle) extends northwest. The cliff scenery and the beautiful valley of Glenagiveny attract many visitors.

3mi/5km north of Cardonagh is Malin, from which the R242 leads past a handsome 18th C. mansion, Malin Hall (1758), to Malin Head, with magnificent cliff scenery.

From Carrowmore the R238 continues southeast to Moville, a popular resort on Lough Foyle. From here there is a ferry service (only in summer; cars not carried) to Oban in Scotland.

From Inishowen Head, the circuit of the peninsula can be completed by following the R238 along the shores of Lough Foyle to Muff (border crossing to Londonderry in Northern Ireland) and continuing west on the R239 to rejoin the R238 south of Burnfoot.
Due to Muff's location, the town has experienced great growth as people from Northern Ireland move across the border. Muff is also notable for its renowned diving center on the outskirts.

Tullyarvan Mill, erected in the 19th C., stands at the edge of Buncrana on the road to Duncree Head. It has been carefully restored and now houses a community centre which includes restaurant and 52 bed hostel.
