Porz Alliou
Porz Alliou is an unsupervised beach on the Île-de-Batz, the small island just off Roscoff, where you anchor off and dinghy ashore to a quiet, wild stretch of Breton coastline. The island is flat and compact — easy to explore on foot along low-lying trails — and feels a world away from the bustle of the Roscoff ferry terminal visible across the water.
