Cycling the Inishowen 100: Ireland's Northern Tip
A 100-mile loop through Mamore Gap, Malin Head and Five Finger Strand, split into six sections. Mamore is the climb that catches people out.
Introduction
The Inishowen Peninsula, jutting out at the north-west of County Donegal, is Ireland’s most northerly mainland point. The cliffs are high, the beaches are long and mostly empty, and the hills keep arriving. The Inishowen 100, a roughly 100-mile (160 km) coastal loop, runs from flat seafront at Buncrana to the Mamore Gap, which is the hardest climb on the peninsula by some margin. Fit riders take it on in a day. Most people give it two or three.
Why Cycle Inishowen?
| Feature | Benefit for Cyclists |
|---|---|
| Coastal scenery | Panoramic Atlantic vistas, sandy beaches and rugged cliffs along the Wild Atlantic Way. |
| Varied terrain | Flat seafront sections (Buncrana, Malin Head) contrast with challenging climbs (Mamore Gap, Urris Hills). |
| Cultural highlights | Ancient forts (Grianán of Aileach), Doagh Famine Village, and traditional villages. |
| Low traffic | Many B-class roads have light motor traffic, especially outside peak tourist season. |
| Bike-friendly services | Several B&Bs, hostels and hotels offer secure bike storage; bike-hire shops in Buncrana and Ballyliffin. |
| Year-round accessibility | Mild maritime climate means the loop is rideable most of the year, with each season offering a different charm. |
The Inishowen 100: Route Overview
The Inishowen 100 is not a single, officially signposted route; rather, it is a circuit that can be started at any convenient point. Most cyclists begin at Grianán of Aileach (the historic stone fort near the centre of the peninsula) and travel clockwise to finish back at the start. The loop can be broken into six logical sections, each with its own character and key stops.
1. Grianán of Aileach → Lisfannon Beach (≈ 12 km)
- Highlights: Panoramic views from the 6th-century ring fort; quick descent to the coastal road.
- Terrain: Short, steady climb up to the fort (≈ 80 m gain) then a gentle roll to the sea.
- Stop: Grab a coffee at Tank & Skinny’s in Buncrana before heading out.
2. Lisfannon → Fort Dunree & Mamore Gap (≈ 30 km)
- Highlights: Lisfannon Beach’s boomerang-shaped sands, historic Fort Dunree museum, and the dramatic Mamore Gap ascent.
- Mamore Gap: Roughly 6 km of twisty road, climbing ~600 m (average gradient 10 %). The surface is rough in places, which is why a road bike feels out of its depth here.
- Detour: Optional short drive to Glenevin Waterfall (40 ft waterfall, 30-minute walk each way).
3. Mamore Gap → Tullagh Strand → Ballyliffin (≈ 20 km)
- Highlights: Sweeping views over the Urris Hills, the horseshoe-shaped Tullagh Strand, and the surf-friendly Ballyliffin Beach.
- Food: Stop for a bite at Nancy’s Barn (Ballyliffin), famous for hearty Irish fare.
4. Ballyliffin → Doagh Famine Village → Five Finger Strand (≈ 15 km)
- Highlights: Insightful visit to Doagh Famine Village (interactive 35-45 min tour), then a walk on the remote Five Finger Strand.
- Viewpoint: Knockamany looks out over the whole run of coastline.
5. Five Finger Strand → Malin Head → Culdaff (≈ 25 km)
- Highlights: Reaching Malin Head, Ireland’s most northerly point (the “Banba’s Crown”), and the EIRE 80 sign.
- Walks: A short 50-minute coastal walk from the headland showcases cliffs, sea stacks and seabird colonies.
- Break: Refuel at Cúl a’ Tí (Culdaff), a cosy café with bike-rack facilities.
6. Culdaff → Kinnagoe Bay → Magilligan Point → Stroove Beach (≈ 18 km)
- Highlights: The secluded Kinnagoe Bay (site of the 1588 Spanish Armada wreck), Magilligan Point viewpoint, and the final stretch to Stroove Beach and the historic Inishowen Lighthouse.
- Finale: Celebrate the loop with a sunset walk along Stroove Beach; the Inishowen Head Walk begins here for those wanting a longer hike.
Total distance
- Road distance: ~ 100 miles (160 km)
- Estimated ride time: 5–6 hours for fit cyclists on the full loop; most riders split the journey over 2-3 days to enjoy stops and reduce fatigue.
Practical Considerations
Bike Choice & Gear
| Bike type | Suitability on Inishowen 100 |
|---|---|
| Road bike | Fast on flat sections; may struggle on Mamore Gap’s rough surface. |
| Gravel bike | Ideal, wide tyres handle mixed tarmac and occasional gravel; comfortable on climbs. |
| Hybrid/Commuter | Acceptable for the coastal flats; avoid if you plan to push the Mamore Gap hard. |
| Mountain bike | Overkill for most of the route; useful only for off-road detours (e.g., Glenevin Waterfall). |
Essential gear: waterproof jacket, layered clothing, spare tubes, puncture-repair kit, bike lock, map or GPS device (offline maps recommended), and a basic first-aid kit.
Navigation
- Offline maps: Download the Inishowen 100 GPX from the Irish Road Trip site or use Komoot’s “Inishowen Loop” guide (downloadable for free).
- Signage: The route is not signposted; rely on turn-by-turn directions from the GPX file and the printed itinerary below.
- Mobile coverage: Generally good along the main road, but can be spotty in remote sections (e.g., Kinnagoe Bay). Keep a paper map as backup.

Weather & Best Time to Ride
| Season | Typical Conditions | Pros | Cons |
|---|---|---|---|
| Late Spring (May-June) | Mild temps (12-17 °C), longer daylight (≈ 17 h) | Blooming flora, fewer crowds | Occasional rain showers |
| Summer (July-August) | Warmest (15-20 °C), up to 20 h daylight | Best for beach stops | Higher traffic, possible wind gusts |
| Early Autumn (Sept-Oct) | Comfortable temps (13-18 °C), autumn colours | Quieter roads, crisp air | Shorter days, more rain |
| Winter (Nov-Feb) | Cold (5-10 °C), strong Atlantic winds | Very quiet, dramatic sea-scapes | Limited services, daylight < 8 h |
Tip: The Atlantic can generate strong cross-winds, especially on exposed sections like Malin Head. Carry a wind-breaker and check marine forecasts before setting out.
Safety & Etiquette
- Wear a helmet: legally required for riders under 18 and strongly recommended for all.
- Stay visible: bright clothing, front and rear lights, especially in winter or on misty mornings.
- Share the road: many sections are narrow two-lane roads. Signal well, keep to the left, and give motor-vehicles ample passing space.
- Respect private land: some farm tracks intersect the loop; ask permission before using them.
- Leave no trace: carry out all litter, stick to designated car parks, and avoid trampling sensitive dune vegetation.
Seasonal Highlights & Stops Worth Making
- Birdwatching at Malin Head: a hotspot for puffins, guillemots and razorbills during spring and early summer.
- Sunset at Stroove Beach: the lighthouse in silhouette, with the Inishowen Head Walk starting from the same spot.
- Historical immersion at Doagh Famine Village: interactive exhibits on 19th-century life, and the tour runs 35 to 45 minutes.
- Surf culture at Tullagh Strand: watch local surfers ride the Atlantic swells; the beach also hosts occasional surf festivals.
- Armada relics at Kinnagoe Bay: a chance to spot the remains of the Spanish Armada shipwreck (subject to tide).

Final Thoughts
The loop is harder than the distance suggests, and the wind is the reason. Coming off the Atlantic on exposed sections like Malin Head, a cross-wind will cost you more time than Mamore Gap does. Services are scarce between villages, so carry food, a spare tube and enough water to get you to the next café rather than the next town.
Take the gravel bike if you have one. Check the marine forecast the night before, start early, and if the wind is up, take the extra day rather than fighting it.
