The ferry from Oban to Castlebay takes about five hours. We would have preferred to stay in the camper for the journey but maritime safety regulations don’t allow for that. So up we went to the passenger decks, which had a very familiar B.C. Ferries vibe to them. We spent most of our time on the outside decks as the designated pet areas were quite stuffy and poorly ventilated. Once we had sailed through the Sound of Mull and past the Small Isles the horizon began to blend into the low cloud and a strange feeling of being lost at sea set in.
