WC300 Traveller's Note

Sea Roads & Open Horizons

Overview: Inveraray – Oban

Leaving Inveraray, the WC300 follows Loch Fyne south before turning inland to Lochgilphead and the open country of mid-Argyll. Beyond it lies Kilmartin Glen, one of Scotland’s richest concentrations of prehistoric monuments — cairns, standing stones and ancient earthworks scattered across a quietly remarkable landscape.

From Kilmartin the route turns west to meet the coast near Arduaine, then north through Kilmore towards Oban. The descent into town delivers a real sense of arrival: a working harbour framed by ferries and fishing boats, McCaig’s Tower on the hill above, and the islands of the Firth of Lorn spread out across the water — the WC300’s first proper west coast town.

Arduaine Slipway

This small slipway offers an unfiltered glimpse of Scotland’s Atlantic coast. On calm days the water stretches quietly towards the islands, but when the weather turns the sea becomes part of the spectacle. Waves crash against the rocks, the wind carries the salt spray inland, and the coastline reveals a wilder side of Argyll that fair-weather photographs rarely capture.

Route Highlights

Loch Fyne — Southern Shore

The A83 follows Loch Fyne south from Inveraray. The loch narrows as the road progresses and the hills of Cowal rise across the water. A quieter stretch than the northern shore.

Lochgilphead

The principal town of mid-Argyll, sitting at the head of Loch Gilp. A practical pause point — fuel, provisions and the last services before Kilmartin Glen.

Kilmartin Glen

One of Scotland’s most significant prehistoric landscapes. Over 350 ancient monuments within a six-mile radius — cairns, stone circles, rock art and standing stones spanning five thousand years of human activity. The landscape is open and quietly compelling.

Kilmartin Village

The natural base for exploring the glen. The parish church contains a remarkable collection of medieval grave slabs and early Christian carved stones gathered from across mid-Argyll.

Arduaine Coast

Where the route meets the Argyll coast, views open west across the Firth of Lorn toward Luing, Scarba and the distant outline of Jura. The coastline is rocky and indented, with small sea lochs cutting inland.

Kilmore

The distinctive church tower at Kilmore is an easily recognised landmark on the approach to Oban.

Oban

The principal town of the west Highland coast and the WC300’s first major arrival point. The harbour is active with CalMac ferries serving the islands. McCaig’s Tower on the hill above gives commanding views across the bay and islands.

Photography Tip

Catch the late light at Arduaine

The stretch between Arduaine and Kilmelford offers some of the finest evening light on the route. Low sun catches the islands offshore while the sea reflects the changing sky.

Photography Highlights

Photography Highlights

Kilmartin Glen — Linear Cairns

Open valley floor with ancient cairns as foreground. Overcast light works well — no harsh shadows on the stonework. Early morning before other visitors arrive.
Best time: Early morning
Best season: April–October

Photography Highlights

Dunadd Hillfort Summit

Elevated view across the Moine Mhòr wetlands and Kilmartin Glen. The carved footprint in the rock is a compelling close-up subject.
Best time: Morning
Best season: May–September

Lesser Known Stops

Lesser Known Stops

Dunadd Hillfort

Visible from the A816 as a rocky summit rising from the Moine Mhòr wetland. The short walk to the summit is straightforward and the carved inauguration stones are among the most historically significant in Scotland. Passed by most travellers without a second glance.

Lesser Known Stops

Moine Mhòr National Nature Reserve

One of the largest remaining lowland raised bogs in Britain. A boardwalk trail crosses the wetland — birdlife including hen harrier, curlew and snipe is exceptional in spring and early summer.

Wildlife & Nature

Wildlife Intelligence

  • White-tailed eagle – scan wooded hillsides above the A816; size relative to buzzards is the most reliable identifier; wingspan up to 2.4 metres
  • Otter – small sea lochs near Arduaine at low tide; approach from downwind; spraints on rocks indicate regular activity
  • Hen harrier – open moorland north of Lochgilphead; low quartering flight; most active in morning
  • Grey seal – rocky skerries off Arduaine coast; most visible at low tide haul-outs
  • Bottlenose dolphin – Firth of Lorn approaching Oban; scan from elevated coastal viewpoints in calm conditions
  • Orca – rare but memorable visitors to the west coast. Recent sightings have been recorded near Oban and in the Firth of Lorn. Sightings remain uncommon, but these waters support the marine life that occasionally attracts them.

Local Knowledge

Local Knowledge

  • Kilmartin Glen is best explored on foot between monuments — distances are manageable and the landscape makes more sense at walking pace
  • Dunadd is visible from the road but almost no one stops; the summit view and carved stones make it one of the most rewarding short walks on the entire WC300
  • Oban is busiest midday to late afternoon in summer; arriving early or in the evening makes a significant difference
  • The Arduaine coastal stretch is one of the quieter sections of the A816 — drive slowly and watch the water
  • Lochgilphead is a practical stop rather than a destination; fuel and provisions here before Kilmartin Glen
  • Mobile signal can be unreliable between Kilmartin and Arduaine; download maps before leaving Lochgilphead

Good to Know

  • Fuel – Inveraray, Lochgilphead and Oban; no fuel between Lochgilphead and Oban
  • Toilets – Inveraray, Lochgilphead, Kilmartin area, Oban
  • Mobile signal – good through main corridor; variable between Kilmartin and Arduaine
  • Kilmartin Glen – monuments are spread across several miles; a car is useful for covering the full glen efficiently
  • Oban parking – waterfront parking fills early in summer; arriving before midday recommended
  • Oban ferries – if continuing to island WC300+ Extensions, book well in advance for summer travel
  • Road type – A83 and A816 throughout; well surfaced; some narrow sections on the Arduaine coastal stretch
  • Single track – none on core route; some minor roads around Kilmartin monuments involve single track

Loch Craignish with the islands beyond – the coastline begins to open towards the Atlantic. On clear days, the western horizon hints at islands still to come.
