It’s not difficult to see why Oban is referred to as the ‘gateway to the lsles’ with such a fantastic range of islands to explore. The main ferry operator is Caledonian MacBrayne and their website gives the information on all ferry crossings, timetables and prices. You can choose from full day exploring options to shorter, 2 hour trips.
The nearest island to Dungallan Country House is Kerrera. It can be reached by a short, 5 minute ferry crossing and the island website is a great source of inspiration for your trip.
