The Inishowen 100 | One of Ireland’s best-kept road trip secrets

The Inishowen Peninsula of Ireland is one of the most dramatic destinations along the Atlantic Coast, where raw ocean energy contrasts beautifully with ancient Irish history. To experience this natural beauty first-hand, the Inishowen 100 is the route to take. This scenic route, located in the county of Donegal, is a spectacular highlight of the wider Wild Atlantic Way network.

You’ll discover deeply historic stops, secluded sandy beaches, hair-raising passes and towering cliffs along this trail. The total length of the route is about 100 miles (160km). It can be done in one long day, but spending 2-3 days gives you the opportunity to take it all in.

Planning a trip here can leave travellers unsure of the duration of their stopovers and how to manage their travel time. Featuring the best places to stop, off-the-beaten-path tips, driving directions, maps and local knowledge, this is your road trip guide to making the most of Inishowen.

What is the Inishowen 100

The Inishowen 100 is a well-known circular scenic driving route in the north of Co. Donegal, Ireland. This walk is a 100-mile (160 km) walk around the outside of the Inishowen Peninsula. It is an integral part of the iconic and breathtaking Wild Atlantic Way route.

The road offers a remarkable variety of landscapes: huge sea cliffs, pristine beaches, traditional villages and high mountain roads. It normally starts and finishes close to Buncrana or Bridgend and is very accessible. It is regarded as one of the best road trips in Ireland, whether you are driving, taking your camper van, motorbike or touring bike.

Where does the Inishowen 100 start and end?

As it is a continuous circle, there is no official starting line for this Inishowen route. The majority of visitors starting their trip find it easiest to start at the largest town on the peninsula, Buncrana, or at the border with Northern Ireland at Bridgend.

The Donegal road trip can be done clockwise or anti-clockwise! It is strongly suggested that driving clockwise is advisable, as it will put the car to the left of the road, nearer the ocean, and provide the most dramatic coastal exposures.

The driving time of the loop, without a stop, is about 4 hours. Realistically, a full day is the minimum time needed, especially if sightseeing is involved.

Local Tip: Refuel early. As you move north and further away from the main road, petrol stations are less frequent.

Best stops along the Inishowen 100

Here are a few of the main loop’s essential Inishowen attractions you need to see to help you plan your trip.

1. Buncrana

Buncrana is the biggest town on the peninsula and is the ideal base for your adventure! It has a vibrant and colourful high street, with good accommodation and old-fashioned pubs. Go for a morning walk through Swan Park, a beautifully restored wooded stroll over the Crana River and down to the sea.

Why visit: Wonderful ambience and facilities.

Insider Tip: Before heading out, grab a cup of coffee at The Oughterlin Café. 

2. Fort Dundee

Located on a prominent promontory overhanging Lough Swilly, Fort Dunree combines military history with stunning views of the coast. This historic fort served as an important defence point during World War I and II. Its on-site museum is now dedicated to interesting military memorabilia today.

Why visit: Excellent wildlife viewing and photo opportunities.

Insider Tip: Get here early in the morning. This will provide the best lighting and avoid the midday crowds. 

3. Mamore Gap

The Mamore Gap is one of the most spectacular passes through the mountains in Ireland. The road leads steeply up through a narrow glaciated U-shaped valley before dropping down towards the Atlantic. The vastness of the surrounding hills is intimidating, and the views from the top are unforgettable.

Why visit: Driving through the pass will be thrilling and the panoramic views will be the reward

Inside Tip: This road is very narrow with extremely sharp hairpin turns. Drivers should drive slowly, particularly when it is cloudy, foggy or raining. 

4. Doagh Famine Village

This open-air heritage museum is a must-visit for anyone wishing to delve deeply into Irish history. Doagh Famine Village presents a deeply moving, interactive experience focused on the Great Famine of the 1840s, rural life and the harsh realities of mass emigration.

Why visit: One of the most immersive and educational attractions on the way.

Insider tip: The guided tours here are great and fun for the whole family. 

5. Malin Head

Malin Head is the most northerly point on the mainland of Ireland and is essential to the drive. This dramatic and rugged landscape is well-known for its wild Atlantic coastlines and was also used as a filming location for Star Wars: The Last Jedi.

Why visit: To stand at the edge of the country at the Banba’s Crown lookout tower.

Insider tip: High winds and unexpected rain are a year-round occurrence. Dress in layers and wear a good waterproof jacket. 

6. Five Finger Strand

Located just south of Milan Head, Five Finger Strand boasts some of the largest and most impressive sand dunes in Europe. The clifftop overlook provides a vast panorama of Trawbreaga Bay.

Why visit: To see one of Donegal’s most photogenic and wild beaches.

Warning: The currents here are well known to be very hazardous. This is an excellent place to go for a sunset stroll, but swimming is not allowed. 

7. Kinnagoe Bay

Kinnagoe Bay is a beautiful secluded horseshoe bay, nestled at the base of a steep hillside. The water turns a stunning turquoise on sunny days, giving it a somewhat tropical feel. It’s also the ancient site where the Spanish Armada ship La Trinidad Valencera sank in 1588.

Why visit: For complete peace and breathtaking coastal views.

Inside Tip: The descent road is very steep and narrow. Don’t rush, and use the designated passing places. 

8. Greencastle

This is the most historic maritime town on the eastern leg of the loop, featuring a charming fishing village. Watch the fishing trawlers as they come home to the harbour, or look across the water to the Magilligan ferry that runs between Donegal and Northern Ireland.

Why visit: A tranquil destination with a great food scene.

Insider Tip: Always stop for a bowl of local seafood chowder or fresh fish and chips right on the pier.
