At the western end of the Geopark, the Crozon Peninsula exhibits many curiosities of the mineral world and offers, on its indented coasts, particularly contrasting coastal landscapes.

Naturally and geologically distinctive features of the peninsula are its approximately 400 marine caves. The opening of these caves is subject to the tides.

The western part of its coastal headlands offers rough and picturesque landscapes, bordered by a succession of cliffs and fine sand beaches. Dry stone low walls made of Armorican Sandstone are still visible today. They were erected by the farmers in the past to protect the cultivated areas next to the traditional hamlets, as seen in the Chèvre Cape.

Moorlands, coastal grasslands, cliffs, pinewoods and coves with turquoise water punctuate this landscape, sometimes with a Mediterranean atmosphere. These are the home of many birds, including the emblematic peregrine falcon and red-billed chough. Here the vegetation is subject to severe soil and climate conditions: it is the favourite place of heather and gorse.

Located between the Brest Bay, the Iroise Sea, and the Douarnenez Bay, the Crozon Peninsula is a real summary of the maritime atmospheres of Brittany. The diversity and the quality of its landscapes give it a reputation for tourism on the international scale.
