CalMac Ferries
Check prices & times »CalMac — Caledonian MacBrayne — is Scotland's main ferry operator, running more than 30 routes across the west coast, the Hebrides and the Firth of Clyde. For most of Scotland's inhabited islands it's the only way to bring a car, and for many island communities it's a lifeline service carrying everything from commuters and tourists to food, fuel and freight.
Owned by the Scottish Government and instantly recognisable by its red-and-white funnels, CalMac carries millions of passengers a year to more than 20 islands. This guide covers the main routes, how fares work, the fleet, and how to book.

How much do CalMac ferries cost? Road Equivalent Tariff explained
CalMac fares are set using Road Equivalent Tariff, or RET — a Scottish Government subsidy that prices a ferry crossing roughly as if you were driving the same distance by road. In practice that keeps island travel genuinely affordable: foot passenger fares on shorter routes can be similar to a short train ticket, and taking a car across, while more expensive, is reasonable by international ferry standards.
- Fares: charged separately for passengers and vehicles
- Pets: travel free
- Overnight crossings: cabin accommodation included in the fare
Island hopping: Hopscotch tickets
If you're visiting more than one island, CalMac's Hopscotch tickets let you link a series of crossings into a single fixed-route itinerary, usually working out cheaper than buying each leg separately.
They're popular with touring visitors combining, say, Mull, the Outer Hebrides and Skye into one trip, returning to the mainland from a different port than you left. It's worth planning your route before booking, as the ticket follows a set sequence of crossings.
The CalMac fleet
CalMac operates a fleet of around 31 vessels, ranging from large cruise ferries roughly the length of a football pitch on the longer routes to small, modern hybrid vessels serving the shorter island crossings.
Larger ships have observation lounges with views over the coast, a Mariners cafeteria serving locally sourced food, and the Cub Club play areas for children.
The fleet has faced well-documented challenges in recent years, with an ageing set of vessels and delays to new ships — the new MV Glen Sannox finally entered service on the Arran route in January 2025, with its sister ship MV Glen Rosa expected to follow.
Booking with CalMac and when to travel
CalMac runs a fuller summer timetable from late March to late October and a reduced winter one, and you can book online, by phone or via the CalMac app.
- Vehicles: car deck space sells out faster than passenger space — book well ahead on popular summer routes, and several weeks out for a motorhome
- Foot passengers: far more flexible, often turn-up-and-go, though not guaranteed at peak times
- Shortest crossings: some can't be booked in advance and run first-come, first-served
- Timetables: fuller summer schedule (late March–late October), reduced in winter; book online, by phone, or via the CalMac app
