We recommend taking the short ferry crossing. This saves you the detour over the bridge to the north. This is a good option if there aren't too many cyclists waiting. The ferry only takes three bikes at a time. Payment is made on board, in cash or by debit card.

The Bégo site is a set of German fortifications, dating from the Second World War. These installations of the Atlantic Wall were dedicated to protecting the harbor of Lorient and the U. Boats of Admiral Dönitz and preventing a possible landing of allied troops. Today, the site keeps the memory alive. Tours are organized during high season.
