Route Overview and Operators
The Portsmouth to St Malo ferry route is operated exclusively by Brittany Ferries, using large, well-equipped vessels such as the Pont-Aven. This overnight crossing typically departs in the evening and arrives in France early the next morning, making it ideal for travellers looking to maximise their time on the continent.
Sailings are more frequent between April and October, with up to seven crossings per week during peak summer months. In winter, the schedule reduces to 3–4 sailings per week.
