Whether you're island-hopping through the Inner Hebrides, exploring the medieval heart of Oban, or discovering ancient clan seats along the shores of Loch Fyne, Argyll and the Western Isles offer Scotland at its most ancient and atmospheric.

Getting There

Travelling to Argyll & the Western Isles

Argyll is most easily reached by car from Glasgow (2 hours to Oban via the A82 through Loch Lomond). Oban is the gateway to the islands, with CalMac ferries to Mull, Islay, Colonsay, and beyond. Glasgow Airport is the nearest major airport. For Orkney, fly from Edinburgh, Glasgow, or Inverness to Kirkwall Airport, or take the ferry from Scrabster or Aberdeen. Shetland has flights from Aberdeen, Edinburgh, and Glasgow to Sumburgh Airport, or the overnight NorthLink ferry from Aberdeen.

Within Argyll, a car is essential — distances are long, roads are single-track in places, and public transport is limited. CalMac's Hopscotch tickets offer good value for multi-island ferry trips.


Accommodation

Where to Stay in Argyll & the Western Isles

Oban is the natural hub — a lively harbour town with restaurants, pubs, and good accommodation, plus ferry access to the islands. On Mull, Tobermory (of Balamory fame) is colourful and well-supplied. Orkney's Kirkwall and Stromness have excellent B&Bs and small hotels. In mid-Argyll, Lochgilphead or Crinan are quiet bases near Kilmartin and Dunadd.

For a special experience, stay at Barcaldine Castle (B&B in a 16th-century tower house) or Glengorm Castle on Mull. Wild camping is popular across the islands — Scotland's access rights apply, and the remoteness is part of the appeal.


Planning

Best Time to Visit Argyll & the Western Isles Castles

May to August is peak season — long daylight hours, calmest seas for ferry crossings, and all sites open. June is often the driest month. Ferry schedules are fuller in summer but book ahead for car crossings to Mull, Islay, and the Outer Hebrides — they sell out.

September brings beautiful autumn light and fewer midges. Winter is dramatic but challenging — short days, rough seas can cancel ferries, and many island sites close. However, mainland Argyll castles are accessible year-round, and winter storms create spectacular coastal scenery.


Frequently Asked

Argyll & the Western Isles Castle FAQ

How many castles are in Argyll & the Western Isles?
Around 53 castles, brochs, and historic sites across Argyll and the Western Isles — from Iron Age brochs to medieval clan strongholds.
Can I visit the islands without a car?
Possible but limiting. CalMac ferries take foot passengers, and Mull has limited bus services. But a car opens up far more sites, especially on the mainland. Consider car hire on the islands.
What is the oldest castle in the region?
Castle Sween in Knapdale is one of the oldest stone castles in Scotland (12th century). But the region's fortified sites go back much further — Dun Carloway broch in the Outer Hebrides is a 2,000-year-old Iron Age tower, and Argyll's crannogs and hillforts predate written history.
Is Castle Stalker accessible?
Castle Stalker sits on a tidal island in Loch Laich and is only accessible by boat. It opens for limited tours on select dates in summer — book well in advance. It's stunning from the shore viewpoint on the A828.
Which island should I visit first?
Mull is the easiest — a short ferry from Oban with excellent castles (Duart, Torosay) and a gateway to Iona. Islay offers whisky distillery castles and a wilder feel. The Outer Hebrides (Lewis, Harris) are the most remote and rewarding, with stunning landscapes and ancient sites like Dun Carloway broch.
