The marina was constructed in the early 1970s as part of a major coastal development project to boost tourism in the Rhuys Peninsula.
It is categorized as a Blue Flag harbor, indicating high standards for water quality and environmental management.
The port features a unique 'floating' breakwater system designed to dampen incoming swells from the Atlantic.
During peak season, the marina manages thousands of transient boat movements, making it a critical node for French pleasure boating.
The nearby Petit Mont site overlooks the port and contains burial mounds dating back to 4500 BC.
The harbor basin is deep enough to allow for the maintenance of large sailing catamarans and ocean-going vessels.
The architecture of the surrounding commercial district follows a specific Breton seaside aesthetic influenced by 20th-century urban planning.
Port Crouesty is the largest marina in Brittany, situated at the entrance of the Gulf of Morbihan in Arzon. It functions as a deep-water port capable of accommodating over 1,400 vessels across its various basins. The site serves as a major hub for Atlantic sailing and professional yachting, featuring extensive commercial quays lined with shops and restaurants. It is adjacent to the Fogeo beach and the Petit Mont cairn, a significant Neolithic site. The marina infrastructure includes specialized dry stacking, fuel services, and boat repair facilities. The port area provides direct access to coastal footpaths including the GR34 trail, which circles the Brittany coastline. It is a central point for maritime excursions into the Morbihan archipelago and the island of Houat. The harbor's design utilizes a protected basin structure to maintain operational status during varying tidal cycles.

Walk the coastal path toward the Petit Mont cairn for an elevated view over the entire marina complex.
Check the tide charts before planning boat excursions, as the currents entering the Gulf of Morbihan can be exceptionally strong.
Visit the dedicated chandleries and maritime shops on the Quai des Voiliers if you require specialized sailing gear.
Do not attempt to swim inside the main boat basins due to heavy vessel traffic and underwater infrastructure.
Commercial activity remains year-round, though retail services have reduced staffing during the winter off-season.
Casual, but avoid walking through private marina docks without permission or a valid slip rental.
