Port Ellen to Rubha Glas via Port na Luinge, Mull of Oa and Slugaide Glas

This is a long, committing coastal-and-moorland outing on Islay’s south side, linking Port Ellen with the wild cliffs of the Oa before returning by a quieter inland line toward Rubha Glas. At around 28 km / 17.4 miles with roughly 700 m / 2,300 ft of ascent, it fits a medium rating on paper, but it can feel harder in poor weather because the Oa is exposed, often wet underfoot, and very open to Atlantic wind. Expect a mix of minor road walking out of Port Ellen, rough coastal and moorland paths, clifftop sections, boggier stretches, and some indistinct ground where careful route-finding matters. HiiKER is the navigation tool to have ready before setting out.

The start is best understood as being near Port Ellen Ferry Terminal, Port Ellen, Isle of Islay, PA42, the main landmark and transport hub in the village. Port Ellen itself sits on Islay’s south coast and is the island’s main southern service centre, with shops, accommodation, and ferry access. The route then heads west and south-west toward the Oa peninsula, passing the Kilnaughton Bay side of town and continuing toward the dramatic headlands beyond. Port Ellen is also closely associated with Rubha Glas, the rocky point by the harbour that separates the bays around the village. (islayinfo.com)

The first part of the day is comparatively gentle. Leaving Port Ellen, the route trends out along the road network toward the Oa, giving broad sea views back across Kilnaughton Bay and toward the low, open landscapes that make this part of Islay feel so spacious. Although the total ascent is about 700 m / 2,300 ft, much of it is accumulated in smaller rises rather than one single climb, so the effort builds gradually. If conditions are calm, this opening section can feel straightforward; in wind or rain, it becomes a serious energy drain because there is very little shelter.

Through Port na Luinge and onto the Oa

As the route pushes farther from Port Ellen, the landscape becomes more remote and more elemental. The Oa peninsula is known for its sea cliffs, heath, moorland, freshwater lochs, and rough coastal grassland, and that variety is exactly what gives this walk its character. Ground conditions can change quickly: one stretch may be firm grassy track, the next soft peat or waterlogged path. After rain, expect boggy patches and slower progress than the distance alone suggests. (rspb.org.uk)

Port na Luinge adds a sense of old coastal settlement and working shoreline to the route. Around this side of Islay, place-names often preserve the memory of landing places, small communities, and older Gaelic connections to the sea. Even where there is little built infrastructure now, the coast often hints at former use for fishing, small boats, and local movement between scattered settlements. Hikers should be prepared for rougher footing as the route transitions away from the easier approach and into more exposed terrain.

The approach to the Mull of Oa is one of the most memorable parts of the day. This is where the peninsula narrows into a dramatic clifftop world, with steep drops, open ocean views, and a real sense of being on the edge of the Hebrides. The cliffs here rise to around 200 m / 656 ft in places near the monument area, and in strong wind this section demands caution, especially near cliff edges or on wet grass. Keep well back from the brink in gusty conditions. (islayinfo.com)

Mull of Oa, Slugaide Glas and the historical landscape

The standout landmark on the Oa is the American Monument, set above the cliffs at about 131 m / 430 ft. It commemorates the loss of life from the troopships Tuscania and Otranto, both wrecked off Islay in 1918 during the First World War. This gives the route a strong historical dimension: the scenery is spectacular, but it is also a memorial landscape tied to one of the island’s most poignant wartime stories. The monument is not just a viewpoint; it is one of the key historic sites on Islay’s coast. (portbahnislay.co.uk)

From here, the route’s passage via Slugaide Glas brings a more upland, moorland feel. This is not mountain terrain in the Highland sense, but it is open, path quality can be variable, and visibility can deteriorate quickly in mist. On a clear day, the rewards are wide-ranging views over the Atlantic and across the southern reaches of Islay; in poor weather, this can become the most navigationally demanding part of the walk. Hii
