The 'Pink Granite' color results from the combination of three minerals: mica, feldspar, and quartz.
The beach is home to a specific tidal phenomenon where the water retreats far enough to allow walking to the nearby Île Renote.
Several of the large granite boulders on the beach have been given nicknames by locals due to their resemblance to animals or human objects.
The beach serves as a gateway to the Trégastel Aquarium, which is built directly into the surrounding granite rock formations.
The regional geology dates back approximately 300 million years to the Variscan orogeny period.
Plage du Coz-Pors is the primary beach in the seaside resort of Trégastel, distinguished by its massive, naturally sculpted pink granite boulders. The coastline is part of the Pink Granite Coast (Côte de Granit Rose), characterized by unique geological formations eroded by wind and salt. The beach features fine sand and is flanked by a pedestrian promenade lined with shops and restaurants. It is a family-oriented destination known for its sheltered position within the bay, which reduces heavy swells. During low tide, the receding water reveals a vast expanse of tide pools and access to nearby offshore islets. The beach is monitored by lifeguards during the peak summer season. The area is highly accessible to visitors exploring the local granite trail.
