CalMac Ferries: A Guide to Scotland's Island Ferries

Few ferry networks are as woven into a place as CalMac is into the west of Scotland. Its dark-hulled ships with the red funnels and yellow lion are the lifeline to more than twenty islands — and, for visitors, the scenic, salt-sprayed way into the Hebrides. If you're planning a trip to Arran, Mull, Skye, Lewis or beyond, here's how the system works.

Who are CalMac?

Caledonian MacBrayne (CalMac) runs the ferries along Scotland's west coast and out to the islands of the Firth of Clyde and the Hebrides — over 30 routes serving more than 20 inhabited islands. It's a publicly owned lifeline service that islanders depend on year-round for everything from the weekly shop to hospital trips, which is why the boats run in almost all weathers and the timetable is treated as public infrastructure rather than a tourist attraction.

The main island crossings

The network falls into a few natural clusters:

• The Clyde — the busy commuter-and-holiday crossings closest to Glasgow: Ardrossan to Brodick for the Isle of Arran, and Wemyss Bay to Rothesay for Bute.
• Oban and the southern Hebrides — Oban is the great hub, with sailings to Mull (Craignure), Coll, Tiree, Colonsay and the long run to Barra and South Uist.
• Skye and the Small Isles — the Isle of Skye is reached by road bridge, but the Mallaig to Armadale ferry is a lovely scenic shortcut, and Mallaig also serves the Small Isles of Rum, Eigg, Muck and Canna.
• The Outer Hebrides — Ullapool to Stornoway for the Isle of Lewis, and Uig (Skye) across to Tarbert (Harris) and Lochmaddy (North Uist).

Do you need to book?

It depends on whether you're bringing a vehicle. Foot passengers can almost always turn up and go — just arrive in good time. Vehicles should be booked in advance, especially on the popular routes to Arran, Mull and the Outer Hebrides and throughout the summer, when car-deck space sells out days or weeks ahead. Booking is done online or by phone. Our guide on taking a car on a ferry covers the basics.

Fares: the Road Equivalent Tariff

Scottish island ferries are cheaper than many travellers expect, because they're priced under the Road Equivalent Tariff (RET) — fares are set roughly in line with the cost of driving the equivalent distance by road, as a way of keeping island life affordable. Foot-passenger fares in particular are modest, which makes island-hopping without a car very good value.

Weather and disruption

This is the open Atlantic coast, and weather is part of the deal. Winter gales and summer storms can delay or cancel sailings at short notice, and the anxious refresh of the service-status page is a rite of passage for island travellers. Build slack into any itinerary that depends on a single crossing, and read our guide on whether ferries are cancelled in bad weather before you go.

Island-hopping by CalMac

The network is built for stringing islands together — you can, for example, work up through the Outer Hebrides from Barra to Lewis, or combine Mull with Iona and the smaller isles. CalMac offers multi-crossing "hopscotch" tickets for set island-hopping routes, which can save money over booking each leg separately.
