Port de Piriac-sur-Mer

Tucked into the charming medieval village of Piriac-sur-Mer on the Loire-Atlantique coast, this small harbour maintains a water level of around 2 meters via a sill at the entrance, with a digital depth display to keep you informed. Berths are limited to vessels with a draft under three meters, so it's an intimate spot rather than a bustling hub. The village itself is one of the best-preserved in the region, with stone streets and seafood restaurants just a short walk from the dock.
